MSQ: Improve TooManyBuckets error message, improve error docs. (#13525)
1) Edited the TooManyBuckets error message to mention PARTITIONED BY
   instead of segmentGranularity.

2) Added error-code-specific anchors in the docs.

3) Add information to various error codes in the docs about common
   causes and solutions.

Limit max batch size for segment allocation, add docs (#13503)
Changes:
- Limit max batch size in `SegmentAllocationQueue` to 500
- Rename `batchAllocationMaxWaitTime` to `batchAllocationWaitTime` since the actual
wait time may exceed this configured value.
- Replace usage of `SegmentInsertAction` in `TaskToolbox` with `SegmentTransactionalInsertAction`

Async task client for SeekableStreamSupervisors. (#13354)
Main changes:
1) Convert SeekableStreamIndexTaskClient to an interface, move old code
   to SeekableStreamIndexTaskClientSyncImpl, and add new implementation
   SeekableStreamIndexTaskClientAsyncImpl that uses ServiceClient.
2) Add "chatAsync" parameter to seekable stream supervisors that causes
   the supervisor to use an async task client.
3) In SeekableStreamSupervisor.discoverTasks, adjust logic to avoid making
   blocking RPC calls in workerExec threads.
4) In SeekableStreamSupervisor generally, switch from Futures.successfulAsList
   to FutureUtils.coalesce, so we can better capture the errors that occurred
   with contacting individual tasks.

Other, related changes:
1) Add ServiceRetryPolicy.retryNotAvailable, which controls whether
   ServiceClient retries unavailable services. Useful since we do not
   want to retry calls unavailable tasks within the service client. (The
   supervisor does its own higher-level retries.)
2) Add FutureUtils.transformAsync, a more lambda friendly version of
   Futures.transform(f, AsyncFunction).
3) Add FutureUtils.coalesce. Similar to Futures.successfulAsList, but
   returns Either instead of using null on error.
4) Add JacksonUtils.readValue overloads for JavaType and TypeReference.

Fix issues with caching cost strategy (#13321)
`cachingCost` strategy has some discrepancies when compared to cost strategy.
This commit addresses two of these by retaining the same behaviour as the `cost` strategy
when computing the cost of moving a segment to a server:
- subtract the self cost of a segment if it is being served by the target server
- subtract the cost of segments that are marked to be dropped

Other changes:
- Add tests to verify fixed strategy. These tests would fail without the fixes made to `CachingCostStrategy.computeCost()`
- Fix the definition of the segment related metrics in the docs.
- Fix some docs issues introduced in #13181

MSQ: Fix task lock checking during publish, fix lock priority. (#13282)
* MSQ: Fix task lock checking during publish, fix lock priority.

Fixes two issues:

1) ControllerImpl did not properly check the return value of
   SegmentTransactionalInsertAction when doing a REPLACE. This could cause
   it to not realize that its locks were preempted.

2) Task lock priority was the default of 0. It should be the higher
   batch default of 50. The low priority made it possible for MSQ tasks
   to be preempted by compaction tasks, which is not desired.

* Restructuring, add docs.

* Add performSegmentPublish tests.

* Fix tests.

Skip ALL granularity compaction (#13304)

Compaction: Fetch segments one at a time on main task; skip when possible. (#13280)
* Compaction: Fetch segments one at a time on main task; skip when possible.

Compact tasks include the ability to fetch existing segments and determine
reasonable defaults for granularitySpec, dimensionsSpec, and metricsSpec.
This is a useful feature that makes compact tasks work well even when the
user running the compaction does not have a clear idea of what they want
the compacted segments to be like.

However, this comes at a cost: it takes time, and disk space, to do all
of these fetches. This patch improves the situation in two ways:

1) When segments do need to be fetched, download them one at a time and
   delete them when we're done. This still takes time, but minimizes the
   required disk space.

2) Don't fetch segments on the main compact task when they aren't needed.
   If the user provides a full granularitySpec, dimensionsSpec, and
   metricsSpec, we can skip it.

* Adjustments.

* Changes from code review.

* Fix logic for determining rollup.

Always return sketches from DS_HLL, DS_THETA, DS_QUANTILES_SKETCH. (#13247)
* Always return sketches from DS_HLL, DS_THETA, DS_QUANTILES_SKETCH.

These aggregation functions are documented as creating sketches. However,
they are planned into native aggregators that include finalization logic
to convert the sketch to a number of some sort. This creates an
inconsistency: the functions sometimes return sketches, and sometimes
return numbers, depending on where they lie in the native query plan.

This patch changes these SQL aggregators to _never_ finalize, by using
the "shouldFinalize" feature of the native aggregators. It already
existed for theta sketches. This patch adds the feature for hll and
quantiles sketches.

As to impact, Druid finalizes aggregators in two cases:

- When they appear in the outer level of a query (not a subquery).
- When they are used as input to an expression or finalizing-field-access
  post-aggregator (not any other kind of post-aggregator).

With this patch, the functions will no longer be finalized in these cases.

The second item is not likely to matter much. The SQL functions all declare
return type OTHER, which would be usable as an input to any other function
that makes sense and that would be planned into an expression.

So, the main effect of this patch is the first item. To provide backwards
compatibility with anyone that was depending on the old behavior, the
patch adds a "sqlFinalizeOuterSketches" query context parameter that
restores the old behavior.

Other changes:

1) Move various argument-checking logic from runtime to planning time in
   DoublesSketchListArgBaseOperatorConversion, by adding an OperandTypeChecker.

2) Add various JsonIgnores to the sketches to simplify their JSON representations.

3) Allow chaining of ExpressionPostAggregators and other PostAggregators
   in the SQL layer.

4) Avoid unnecessary FieldAccessPostAggregator wrapping in the SQL layer,
   now that expressions can operate on complex inputs.

5) Adjust return type to thetaSketch (instead of OTHER) in
   ThetaSketchSetBaseOperatorConversion.

* Fix benchmark class.

* Fix compilation error.

* Fix ThetaSketchSqlAggregatorTest.

* Hopefully fix ITAutoCompactionTest.

* Adjustment to ITAutoCompactionTest.

Two main changes:

1) Add estimateHeapFootprint to LookupExtractor.

2) Use this in MSQ's IndexerWorkerContext when determining the total

This prevents MSQ tasks from running out of memory when there are lookups
defined in the cluster.

Async reads for JDBC (#13196)
Async reads for JDBC:
Prevents JDBC timeouts on long queries by returning empty batches
when a batch fetch takes too long. Uses an async model to run the
result fetch concurrently with JDBC requests.

Fixed race condition in Druid's Avatica server-side handler

Various documentation updates. (#13107)
* Various documentation updates.

1) Split out "data management" from "ingestion". Break it into thematic pages.

2) Move "SQL-based ingestion" into the Ingestion category. Adjust content so
   all conceptual content is in concepts.md and all syntax content is in reference.md.
   Shorten the known issues page to the most interesting ones.

3) Add SQL-based ingestion to the ingestion method comparison page. Remove the
   index task, since index_parallel is just as good when maxNumConcurrentSubTasks: 1.

4) Rename various mentions of "Druid console" to "web console".

5) Add additional information to ingestion/partitioning.md.

6) Remove a mention of Tranquility.

7) Remove a note about upgrading to Druid 0.10.1.

8) Remove no-longer-relevant task types from ingestion/tasks.md.

9) Move ingestion/native-batch-firehose.md to the hidden section. It was previously deprecated.

10) Move ingestion/native-batch-simple-task.md to the hidden section. It is still linked in some
    places, but it isn't very useful compared to index_parallel, so it shouldn't take up space
    in the sidebar.

11) Make all br tags self-closing.

12) Certain other cosmetic changes.

13) Update to node-sass 7.

compressed big decimal - module (#10705)
Compressed Big Decimal is an extension which provides support for 
Mutable big decimal value that can be used to accumulate values 
without losing precision or reallocating memory. This type helps in 
absolute precision arithmetic on large numbers in applications, 
where greater level of accuracy is required, such as financial 
applications, currency based transactions. This helps avoid rounding 
issues where in potentially large amount of money can be lost.

Accumulation requires that the two numbers have the same scale, 
but does not require that they are of the same size. If the value 
being accumulated has a larger underlying array than this value 
(the result), then the higher order bits are dropped, similar to what 
happens when adding a long to an int and storing the result in an 
int. A compressed big decimal that holds its data with an embedded 
array.

Compressed big decimal is an absolute number based complex type 
based on big decimal in Java. This supports all the functionalities 
supported by Java Big Decimal. Java Big Decimal is not mutable in 
order to avoid big garbage collection issues. Compressed big decimal 
is needed to mutate the value in the accumulator.

which was rewritten in #12481 to use MXBeans instead.

* json_value adjustments
changes:
* native json_value expression now has optional 3rd argument to specify type, which will cast all values to the specified type
* rework how JSON_VALUE is wired up in SQL. Now we are using a custom convertlet to translate JSON_VALUE(... RETURNING type) into dedicated JSON_VALUE_BIGINT, JSON_VALUE_DOUBLE, JSON_VALUE_VARCHAR, JSON_VALUE_ANY instead of using the calcite StandardConvertletTable that wraps JSON_VALUE_ANY in a CAST, so that we preserve the typing of JSON_VALUE to pass down to the native expression as the 3rd argument

* fix json_value_any to be usable by humans too, coverage

* fix bug

* checkstyle

* validate that options to json_value are the supported options rather than ignore them

Change Kafka Lookup Extractor to not register consumer group (#12842)
* change kafka lookups module to not commit offsets

The current behaviour of the Kafka lookup extractor is to not commit
offsets by assigning a unique ID to the consumer group and setting
auto.offset.reset to earliest. This does the job but also pollutes the
Kafka broker with a bunch of "ghost" consumer groups that will never again be
used.

To fix this, we now set enable.auto.commit to false, which prevents the
ghost consumer groups being created in the first place.

* update docs to include new enable.auto.commit setting behaviour

* update kafka-lookup-extractor documentation

Provide some additional detail on functionality and configuration.
Hopefully this will make it clearer how the extractor works for
developers who aren't so familiar with Kafka.

* add comments better explaining the logic of the code

* add spelling exceptions for kafka lookup docs

Adjust "in" filter null behavior to match "selector". (#12863)
* Adjust "in" filter null behavior to match "selector".

Now, both of them match numeric nulls if constructed with a "null" value.

This is consistent as far as native execution goes, but doesn't match
the behavior of SQL = and IN. So, to address that, this patch also
updates the docs to clarify that the native filters do match nulls.

This patch also updates the SQL docs to describe how Boolean logic is
handled in addition to how NULL values are handled.

Fixes #12856.

* Fix test.

Kinesis ingestion with empty shards (#12792)
Kinesis ingestion requires all shards to have at least 1 record at the required position in druid.
Even if this is satisified initially, resharding the stream can lead to empty intermediate shards. A significant delay in writing to newly created shards was also problematic.

Kinesis shard sequence numbers are big integers. Introduce two more custom sequence tokens UNREAD_TRIM_HORIZON and UNREAD_LATEST to indicate that a shard has not been read from and that it needs to be read from the start or the end respectively.
These values can be used to avoid the need to read at least one record to obtain a sequence number for ingesting a newly discovered shard.

If a record cannot be obtained immediately, use a marker to obtain the relevant shardIterator and use this shardIterator to obtain a valid sequence number. As long as a valid sequence number is not obtained, continue storing the token as the offset.

These tokens (UNREAD_TRIM_HORIZON and UNREAD_LATEST) are logically ordered to be earlier than any valid sequence number.

However, the ordering requires a few subtle changes to the existing mechanism for record sequence validation:

The sequence availability check ensures that the current offset is before the earliest available sequence in the shard. However, current token being an UNREAD token indicates that any sequence number in the shard is valid (despite the ordering)

Kinesis sequence numbers are inclusive i.e if current sequence == end sequence, there are more records left to read.
However, the equality check is exclusive when dealing with UNREAD tokens.

Improved Java 17 support and Java runtime docs. (#12839)
* Improved Java 17 support and Java runtime docs.

1) Add a "Java runtime" doc page with information about supported
   Java versions, garbage collection, and strong encapsulation..

2) Update asm and equalsverifier to versions that support Java 17.

3) Add additional "--add-opens" lines to surefire configuration, so
   tests can pass successfully under Java 17.

4) Switch openjdk15 tests to openjdk17.

5) Update FrameFile to specifically mention Java runtime incompatibility
   as the cause of not being able to use Memory.map.

6) Update SegmentLoadDropHandler to log an error for Errors too, not
   just Exceptions. This is important because an IllegalAccessError is
   encountered when the correct "--add-opens" line is not provided,
   which would otherwise be silently ignored.

7) Update example configs to use druid.indexer.runner.javaOptsArray
   instead of druid.indexer.runner.javaOpts. (The latter is deprecated.)

* Adjustments.

* Use run-java in more places.

* Add run-java.

* Update .gitignore.

* Exclude hadoop-client-api.

Brought in when building on Java 17.

* Swap one more usage of java.

* Fix the run-java script.

* Fix flag.

* Include link to Temurin.

* Spelling.

* Update examples/bin/run-java

Use nonzero default value of maxQueuedBytes. (#12840)
* Use nonzero default value of maxQueuedBytes.

The purpose of this parameter is to prevent the Broker from running out
of memory. The prior default is unlimited; this patch changes it to a
relatively conservative 25MB.

This may be too low for larger clusters. The risk is that throughput
can decrease for queries with large resultsets or large amounts of intermediate
data. However, I think this is better than the risk of the prior default, which
is that these queries can cause the Broker to go OOM.

* Alter calculation.

Automatic sizing for GroupBy dictionaries. (#12763)
* Automatic sizing for GroupBy dictionary sizes.

Merging and selector dictionary sizes currently both default to 100MB.
This is not optimal, because it can lead to OOM on small servers and
insufficient resource utilization on larger servers. It also invites
end users to try to tune it when queries run out of dictionary space,
which can make things worse if the end user sets it to too high.

So, this patch:

- Adds automatic tuning for selector and merge dictionaries. Selectors
  use up to 15% of the heap and merge buffers use up to 30% of the heap
  (aggregate across all queries).

- Updates out-of-memory error messages to emphasize enabling disk
  spilling vs. increasing memory parameters. With the memory parameters
  automatically sized, it is more likely that an end user will get
  benefit from enabling disk spilling.

- Removes the query context parameters that allow lowering of configured
  dictionary sizes. These complicate the calculation, and I don't see a
  reasonable use case for them.

* Adjust tests.

* Review adjustments.

* Additional comment.

* Remove unused import.

Able to filter Cloud objects with glob notation. (#12659)
In a heterogeneous environment, sometimes you don't have control over the input folder. Upstream can put any folder they want. In this situation the S3InputSource.java is unusable.

Most people like me solved it by using Airflow to fetch the full list of parquet files and pass it over to Druid. But doing this explodes the JSON spec. We had a situation where 1 of the JSON spec is 16MB and that's simply too much for Overlord.

This patch allows users to pass {"filter": "*.parquet"} and let Druid performs the filtering of the input files.

I am using the glob notation to be consistent with the LocalFirehose syntax.

Two changes that make log behavior cleaner:

2) Use log/ instead of bin/log/ for the default log directory. Makes them

ConcurrentGrouper: Add mergeThreadLocal option, fix bug around the switch to spilling. (#12513)
* ConcurrentGrouper: Add option to always slice up merge buffers thread-locally.

Normally, the ConcurrentGrouper shares merge buffers across processing
threads until spilling starts, and then switches to a thread-local model.
This minimizes memory use and reduces likelihood of spilling, which is
good, but it creates thread contention. The new mergeThreadLocal option
causes a query to start in thread-local mode immediately, and allows us
to experiment with the relative performance of the two modes.

* Fix grammar in docs.

SQL: Add is_active to sys.segments, update examples and docs. (#11550)
* SQL: Add is_active to sys.segments, update examples and docs.

is_active is short for:

  (is_published = 1 AND is_overshadowed = 0) OR is_realtime = 1

It's important because this represents "all the segments that should
be queryable, whether or not they actually are right now". Most of the
time, this is the set of segments that people will want to look at.

The web console already adds this filter to a lot of its queries,
proving its usefulness.

This patch also reworks the caveat at the bottom of the sys.segments
section, so its information is mixed into the description of each result
field. This should make it more likely for people to see the information.

Enable vectorized virtual column processing by default. (#12520)
In the majority of cases, this improves performance.

There's only one case I'm aware of where this may be a net negative: for time_floor(__time, <period>) where there are many repeated __time values. In nonvectorized processing, SingleLongInputCachingExpressionColumnValueSelector implements an optimization to avoid computing the time_floor function on every row. There is no such optimization in vectorized processing.

IMO, we shouldn't mention this in the docs. Rationale: It's too fiddly of a thing: it's not guaranteed that nonvectorized processing will be faster due to the optimization, because it would have to overcome the inherent speed advantage of vectorization. So it'd always require testing to determine the best setting for a specific dataset. It would be bad if users disabled vectorization thinking it would speed up their queries, and it actually slowed them down. And even if users do their own testing, at some point in the future we'll implement the optimization for vectorized processing too, and it's likely that users that explicitly disabled vectorization will continue to have it disabled. I'd like to avoid this outcome by encouraging all users to enable vectorization at all times. Really advanced users would be following development activity anyway, and can read this issue

Enforce console logging for peon process (#12067)
Currently all Druid processes share the same log4j2 configuration file located in _common directory. Since peon processes are spawned by middle manager process, they derivate the environment variables from the middle manager. These variables include those in the log4j2.xml controlling to which file the logger writes the log.

But current task logging mechanism requires the peon processes to output the log to console so that the middle manager can redirect the console output to a file and upload this file to task log storage.

So, this PR imposes this requirement to peon processes, whatever the configuration is in the shared log4j2.xml, peon processes always write the log to console.

Add setProcessingThreadNames context parameter. (#12514)
setting thread names takes a measurable amount of time in the case where segment scans are very quick. In high-QPS testing we found a slight performance boost from turning off processing thread renaming. This option makes that possible.

Allow coordinator to be configured to kill segments in future (#10877)
Allow a Druid cluster to kill segments whose interval_end is a date in the future. This can be done by setting druid.coordinator.kill.durationToRetain to a negative period. For example PT-24H would allow segments to be killed if their interval_end date was 24 hours or less into the future at the time that the kill task is generated by the system.

A cluster operator can also disregard the druid.coordinator.kill.durationToRetain entirely by setting a new configuration, druid.coordinator.kill.ignoreDurationToRetain=true. This ignores interval_end date when looking for segments to kill, and instead is capable of killing any segment marked unused. This new configuration is off by default, and a cluster operator should fully understand and accept the risks if they enable it.

Add a metric for task duration in the pending queue (#12492)
This PR is to measure how long a task stays in the pending queue and emits the value with the metric task/pending/time. The metric is measured in RemoteTaskRunner and HttpRemoteTaskRunner.

An example of the metric:

```
2022-04-26T21:59:09,488 INFO [rtr-pending-tasks-runner-0] org.apache.druid.java.util.emitter.core.LoggingEmitter - {"feed":"metrics","timestamp":"2022-04-26T21:59:09.487Z","service":"druid/coordinator","host":"localhost:8081","version":"2022.02.0-iap-SNAPSHOT","metric":"task/pending/time","value":8,"dataSource":"wikipedia","taskId":"index_parallel_wikipedia_gecpcglg_2022-04-26T21:59:09.432Z","taskType":"index_parallel"}
```

------------------------------------------
Key changed/added classes in this PR

    Emit metric task/pending/time in classes RemoteTaskRunner and HttpRemoteTaskRunner.
    Update related factory classes and tests.

Reduce allocations due to Jackson serialization. (#12468)
* Reduce allocations due to Jackson serialization.

This patch attacks two sources of allocations during Jackson
serialization:

1) ObjectMapper.writeValue and JsonGenerator.writeObject create a new
   DefaultSerializerProvider instance for each call. It has lots of
   fields and creates pressure on the garbage collector. So, this patch
   adds helper functions in JacksonUtils that enable reuse of
   SerializerProvider objects and updates various call sites to make
   use of this.

2) GroupByQueryToolChest copies the ObjectMapper for every query to
   install a special module that supports backwards compatibility with
   map-based rows. This isn't needed if resultAsArray is set and
   all servers are running Druid 0.16.0 or later. This release was a
   while ago. So, this patch disables backwards compatibility by default,
   which eliminates the need to copy the heavyweight ObjectMapper. The
   patch also introduces a configuration option that allows admins to
   explicitly enable backwards compatibility.

* Add test.

* Update additional call sites and add to forbidden APIs.

Add feature flag for Kinesis listShards API usage (#12383)
listShards API was used to get all the shards for kinesis ingestion to improve its resiliency as part of #12161.

However, this may require additional permissions in the IAM policy where the stream is present. (Please refer to: https://docs.aws.amazon.com/kinesis/latest/APIReference/API_ListShards.html).

A dynamic configuration useListShards has been added to KinesisSupervisorTuningConfig to control the usage of this API and prevent issues upon upgrade. It can be safely turned on (and is recommended when using kinesis ingestion) by setting this configuration to true.

Facilitate lazy initialization of connections to mitigate overwhelming of Coordinator (#12298)
Add config for eager / lazy connection initialization in ResourcePool

Description
Currently, when multiple tasks are launched, each of them eagerly initializes a full pool's worth of connections to the coordinator.

While this is acceptable when the parameter for number of eagerConnections (== maxSize) is small, this can be problematic in environments where it's a large value (say 1000) and multiple tasks are launched simultaneously, which can cause a large number of connections to be created to the coordinator, thereby overwhelming it.

Patch
Nodes like the broker may require eager initialization of resources and do not create connections with the Coordinator.
It is unnecessary to do this with other types of nodes.

A config parameter eagerInitialization is added, which when set to true, initializes the max permissible connections when ResourcePool is initialized.

If set to false, lazy initialization of connection resources takes place.

NOTE: All nodes except the broker have this new parameter set to false in the quickstart as part of this PR

Algorithm
The current implementation relies on the creation of maxSize resources eagerly.

The new implementation's behaviour is as follows:

If a resource has been previously created and is available, lend it.
Else if the number of created resources is less than the allowed parameter, create and lend it.
Else, wait for one of the lent resources to be returned.

Batch ingestion replace (#12137)
* Tombstone support for replace functionality

* A used segment interval is the interval of a current used segment that overlaps any of the input intervals for the spec

* Update compaction test to match replace behavior

* Adapt ITAutoCompactionTest to work with tombstones rather than dropping segments. Add support for tombstones in the broker.

* Style plus simple queriableindex test

* Add segment cache loader tombstone test

* Add more tests

* Add a method to the LogicalSegment to test whether it has any data

* Test filter with some empty logical segments

* Refactor more compaction/dropexisting tests

* Code coverage

* Support for all empty segments

* Skip tombstones when looking-up broker's timeline. Discard changes made to tool chest to avoid empty segments since they will no longer have empty segments after lookup because we are skipping over them.

* Fix null ptr when segment does not have a queriable index

* Add support for empty replace interval (all input data has been filtered out)

* Fixed coverage & style

* Find tombstone versions from lock versions

* Test failures & style

* Interner was making this fail since the two segments were consider equal due to their id's being equal

* Cleanup tombstone version code

* Force timeChunkLock whenever replace (i.e. dropExisting=true) is being used

* Reject replace spec when input intervals are empty

* Documentation

* Style and unit test

* Restore test code deleted by mistake

* Allocate forces TIME_CHUNK locking and uses lock versions. TombstoneShardSpec added.

* Unused imports. Dead code. Test coverage.

* Coverage.

* Prevent killer from throwing an exception for tombstones. This is the killer used in the peon for killing segments.

* Fix OmniKiller + more test coverage.

* Tombstones are now marked using a shard spec

* Drop a segment factory.json in the segment cache for tombstones

* Style

* Style + coverage

* style

* Add TombstoneLoadSpec.class to mapper in test

* Update core/src/main/java/org/apache/druid/segment/loading/TombstoneLoadSpec.java

GroupBy: Cap dictionary-building selector memory usage. (#12309)
* GroupBy: Cap dictionary-building selector memory usage.

New context parameter "maxSelectorDictionarySize" controls when the
per-segment processing code should return early and trigger a trip
to the merge buffer.

Includes:

- Vectorized and nonvectorized implementations.
- Adjustments to GroupByQueryRunnerTest to exercise this code in
  the v2SmallDictionary suite. (Both the selector dictionary and
  the merging dictionary will be small in that suite.)
- Tests for the new config parameter.

* Fix issues from tests.

* Add "pre-existing" to dictionary.

* Simplify GroupByColumnSelectorStrategy interface by removing one of the writeToKeyBuffer methods.

* Adjustments from review comments.

Officially support Java 11. (#12232)
There aren't any changes in this patch that improve Java 11
compatibility; these changes have already been done separately. This
patch merely updates documentation and explicit Java version checks.

The log message adjustments in DruidProcessingConfig are there to make
things a little nicer when running in Java 11, where we can't measure
direct memory _directly_, and so we may auto-size processing buffers
incorrectly.

Adding new config for disabling group by on multiValue column (#12253)
As part of #12078 one of the followup's was to have a specific config which does not allow accidental unnesting of multi value columns if such columns become part of the grouping key.
Added a config groupByEnableMultiValueUnnesting which can be set in the query context.

The default value of groupByEnableMultiValueUnnesting is true, therefore it does not change the current engine behavior.
If groupByEnableMultiValueUnnesting is set to false, the query will fail if it encounters a multi-value column in the grouping key.

Add config to limit task slots for parallel indexing tasks (#12221)
In extreme cases where many parallel indexing jobs are submitted together, it is possible
that the `ParallelIndexSupervisorTasks` take up all slots leaving no slot to schedule
their own sub-tasks thus stalling progress of all the indexing jobs.

Key changes:
- Add config `druid.indexer.runner.parallelIndexTaskSlotRatio` to limit the task slots
  for `ParallelIndexSupervisorTasks` per worker
- `ratio = 1` implies supervisor tasks can use all slots on a worker if needed (default behavior)
- `ratio = 0` implies supervisor tasks can not use any slot on a worker
   (actually, at least 1 slot is always available to ensure progress of parallel indexing jobs)
- `ImmutableWorkerInfo.canRunTask()`
- `WorkerHolder`, `ZkWorker`, `WorkerSelectUtils`

under "Aggregators", about the lgK setting, it said "Must be a power of 2 from 4 to 21 inclusively."  21 is not a power of 2, nor is 12, the given default.  I think there may have been confusion because lgK represents log2 of K.  We could say "K must be a power of 2...", or just say lgK must be between 4 and 21.

Improve the output of SQL explain message (#11908)
Currently, when we try to do EXPLAIN PLAN FOR, it returns the structure of the SQL parsed (via Calcite's internal planner util), which is verbose (since it tries to explain about the nodes in the SQL, instead of the Druid Query), and not representative of the native Druid query which will get executed on the broker side.

This PR aims to change the format when user tries to EXPLAIN PLAN FOR for queries which are executed by converting them into Druid's native queries (i.e. not sys schemas).

Use a simple class to sanitize JDBC exceptions and also log them (#11843)
* Use a simple class to sanitize sanitizable errors and log them

The purpose of this is to sanitize JDBC errors, but can sanitize other errors
if they implement SanitizableError Interface

add a class to log errors and sanitize them
added a simple test that tests out that the error gets sanitized
add @NonNull annotation to serverconfig's ErrorResponseTransfromStrategy

* return less information as part of too many connections, and instead only log specific details

This is so an end user gets relevant information but not too much info since they might now how
many brokers they have

* return only runtime exceptions

added new error types that need to be sanitized
also sanitize deprecated and unsupported exceptions.

* dont reqrewite exceptions unless necessary for checked exceptions

add docs
avoid blanket turning all exceptions into runtime exceptions

* address comments, to fix up docs.

add more javadocs
add support UOE sanitization

* use try catch instead and sanitize at public methods

* checkstyle fixes

* throw noSuchStatement and NoSuchConnection as Avatica is affected by those

* address comments. move log error back to druid meta

clean up bad formatting and commented code. add missed catch for NoSuchStatementException
clean up comments for error handler and add comment explainging not wanting to santize avatica exceptions

* alter test to reflect new error message

Warn if cache size of lookup is beyond max size (#11863)
Enhanced the ExtractionNamespace interface in lookups-cached-global core extension with the ability to set a maxHeapPercentage for the cache of the respective namespace. The reason for adding this functionality, is make it easier to detect when a lookup table grows to a size that the underlying service cannot handle, because it does not have enough memory. The default value of maxHeap for the interface is -1, which indicates that no maxHeapPercentage has been set. For the JdbcExtractionNamespace and UriExtractionNamespace implementations, the default value is null, which will cause the respective service that the lookup is loaded in, to warn when its cache is beyond mxHeapPercentage of the service's configured max heap size. If a positive non-null value is set for the namespace's maxHeapPercentage config, this value will be honored for all services that the respective lookup is loaded onto, and consequently log warning messages when the cache of the respective lookup grows beyond this respective percentage of the services configured max heap size. Warnings are logged every time that either Uri based or Jdbc based lookups are regenerated, if the maxHeapPercentage constraint is violated. No other implementations will log warnings at this time. No error is thrown when the size exceeds the maxHeapPercentage at this time, as doing so could break functionality for existing users. Previously the JdbcCacheGenerator generated its cache by materializing all rows of the underling table in memory at once; this made it difficult to log warning messages in the case that the results from the jdbc query were very large and caused the service to run out of memory. To help with this, this pr makes it so that the jdbc query results are instead streamed through an iterator.

Add Broker config `druid.broker.segment.watchRealtimeNodes` (#11732)
The new config is an extension of the concept of "watchedTiers" where

Similarly, with this config, Broker can choose to skip the realtime nodes and
thus it would query only Historical processes for any given segment.

Remove OffheapIncrementalIndex and clarify aggregator thread-safety needs. (#11124)
* Remove OffheapIncrementalIndex and clarify aggregator thread-safety needs.

This patch does the following:

- Removes OffheapIncrementalIndex.
- Clarifies that Aggregators are required to be thread safe.
- Clarifies that BufferAggregators and VectorAggregators are not
  required to be thread safe.
- Removes thread safety code from some DataSketches aggregators that
  had it. (Not all of them did, and that's OK, because it wasn't necessary
  anyway.)
- Makes enabling "useOffheap" with groupBy v1 an error.

Rationale for removing the offheap incremental index:

- It is only used in one rare scenario: groupBy v1 (which is non-default)
  in "useOffheap" mode (also non-default). So you have to go pretty deep
  into the wilderness to get this code to activate in production. It is
  never used during ingestion.
- Its existence complicates developer efforts to reason about how
  aggregators get used, because the way it uses buffer aggregators is so
  different from how every other query engine uses them.
- It doesn't have meaningful testing.

By the way, I do believe that the given way the offheap incremental index
works, it actually didn't require buffer aggregators to be thread-safe.
It synchronizes on "aggregate" and doesn't call "get" until it has
stopped calling "aggregate". Nevertheless, this is a bother to think about,
and for the above reasons I think it makes sense to remove the code anyway.

* Remove things that are now unused.

* Revert removal of getFloat, getLong, getDouble from BufferAggregator.

* OAK-related warnings, suppressions.

* Unused item suppressions.

* Add druid.sql.approxCountDistinct.function property.

The new property allows admins to configure the implementation for
APPROX_COUNT_DISTINCT and COUNT(DISTINCT expr) in approximate mode.

The motivation for adding this setting is to enable site admins to

For example, an admin can set:

  druid.sql.approxCountDistinct.function = APPROX_COUNT_DISTINCT_DS_HLL

Require Datasource WRITE authorization for Supervisor and Task access (#11718)
Follow up PR for #11680

Description
Supervisor and Task APIs are related to ingestion and must always require Datasource WRITE
authorization even if they are purely informative.

Changes
Check Datasource WRITE in SystemSchema for tables "supervisors" and "tasks"
Check Datasource WRITE for APIs /supervisor/history and /supervisor/{id}/history
Check Datasource for all Indexing Task APIs

Kafka Input Format for headers, key and payload parsing (#11630)
### Description

Today we ingest a number of high cardinality metrics into Druid across dimensions. These metrics are rolled up on a per minute basis, and are very useful when looking at metrics on a partition or client basis. Events is another class of data that provides useful information about a particular incident/scenario inside a Kafka cluster. Events themselves are carried inside kafka payload, but nonetheless there are some very useful metadata that is carried in kafka headers that can serve as useful dimension for aggregation and in turn bringing better insights.

PR(https://github.com/apache/druid/pull/10730) introduced support of Kafka headers in InputFormats.

We still need an input format to parse out the headers and translate those into relevant columns in Druid. Until that’s implemented, none of the information available in the Kafka message headers would be exposed. So first there is a need to write an input format that can parse headers in any given format(provided we support the format) like we parse payloads today. Apart from headers there is also some useful information present in the key portion of the kafka record. We also need a way to expose the data present in the key as druid columns. We need a generic way to express at configuration time what attributes from headers, key and payload need to be ingested into druid. We need to keep the design generic enough so that users can specify different parsers for headers, key and payload.

This PR is designed to solve the above by providing wrapper around any existing input formats and merging the data into a single unified Druid row.

Lets look at a sample input format from the above discussion

"inputFormat":
{
    "type": "kafka",     // New input format type
    "headerLabelPrefix": "kafka.header.",   // Label prefix for header columns, this will avoid collusions while merging columns
    "recordTimestampLabelPrefix": "kafka.",  // Kafka record's timestamp is made available in case payload does not carry timestamp
    "headerFormat":  // Header parser specifying that values are of type string
    {
        "type": "string"
    },
    "valueFormat": // Value parser from json parsing
    {
        "type": "json",
        "flattenSpec": {
          "useFieldDiscovery": true,
          "fields": [...]
        }
    },
    "keyFormat":  // Key parser also from json parsing
    {
        "type": "json"
    }
}

Since we have independent sections for header, key and payload, it will enable parsing each section with its own parser, eg., headers coming in as string and payload as json. 

KafkaInputFormat will be the uber class extending inputFormat interface and will be responsible for creating individual parsers for header, key and payload, blend the data resolving conflicts in columns and generating a single unified InputRow for Druid ingestion. 

"headerFormat" will allow users to plug parser type for the header values and will add default header prefix as "kafka.header."(can be overridden) for attributes to avoid collision while merging attributes with payload.

Kafka payload parser will be responsible for parsing the Value portion of the Kafka record. This is where most of the data will come from and we should be able to plugin existing parser. One thing to note here is that if batching is performed, then the code is augmenting header and key values to every record in the batch.

Kafka key parser will handle parsing Key portion of the Kafka record and will ingest the Key with dimension name as "kafka.key".

## KafkaInputFormat Class: 
This is the class that orchestrates sending the consumerRecord to each parser, retrieve rows, merge the columns into one final row for Druid consumption. KafkaInputformat should make sure to release the resources that gets allocated as a part of reader in CloseableIterator<InputRow> during normal and exception cases.

During conflicts in dimension/metrics names, the code will prefer dimension names from payload and ignore the dimension either from headers/key. This is done so that existing input formats can be easily migrated to this new format without worrying about losing information.

Add Broker config `druid.broker.segment.ignoredTiers` (#11766)
The new config is an extension of the concept of "watchedTiers" where
the Broker can choose to add the info of only the specified tiers to its timeline.
Similarly, with this config, Broker can choose to ignore the segments being served
by the specified historical tiers. By default, no tier is ignored.

This config is useful when you want a completely isolated tier amongst many other tiers.

Say there are several tiers of historicals Tier T1, Tier T2 ... Tier Tn
and there are several brokers Broker B1, Broker B2 .... Broker Bm

If we want only Broker B1 to query Tier T1, instead of setting a long list of watchedTiers
on each of the other Brokers B2 ... Bm, we could just set druid.broker.segment.ignoredTiers=["T1"]
for these Brokers, while Broker B1 could have druid.broker.segment.watchedTiers=["T1"]

Update kinesis-ingestion.md (#11767)
* Update kinesis-ingestion.md

It seems that we are declaring (a final int) recordsPerFetch as 400 and fetchDelayMillis as 0 in https://github.com/implydata/druid/blob/imply-2021.09/extensions-core/kinesis-indexing-service/src/main/java/org/apache/druid/indexing/kinesis/KinesisIndexTaskIOConfig.java#L36

```
public static final int DEFAULT_RECORDS_PER_FETCH = 4000;
public static final int DEFAULT_FETCH_DELAY_MILLIS = 0;
```

updating `recordsPerFetch` and `fetchDelayMillis` to actual default values as hardcoded above .
