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.

* make travis use node12 for docs

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.

Service stdout log files, move logs to log/. (#12570)
* Service stdout log files, move logs to log/.

Two changes that make log behavior cleaner:

1) Redirect messages from the Java runtime to their own log files.
   Otherwise, they would get jumbled up in the output of the all-in-one
   start command.

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

Additionally, add documentation about how to avoid the reflective
access warnings in Java 11.

* Spelling.

* See if code formatting affects spelling.

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.

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.

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

* Test filter with some empty logical segments

* Refactor more compaction/dropexisting tests

* 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

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.

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`

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

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. (#11181)
* 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
switch the default HLL implementation to DataSketches.

For example, an admin can set:

  druid.sql.approxCountDistinct.function = APPROX_COUNT_DISTINCT_DS_HLL

* Fixes

* Fix tests.

* Remove erroneous cannotVectorize.

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"]

Enable routing of SQL queries at Router (#11566)
This PR adds a new property druid.router.sql.enable which allows the
Router to handle SQL queries when set to true.

This change does not affect Avatica JDBC requests and they are still routed
by hashing the Connection ID.

To allow parsing of the request object as a SqlQuery (contained in module druid-sql),
some classes have been moved from druid-server to druid-services with
the same package name.

Update the default maxSegmentsInNodeLoadingQueue from 0 (unbounded) to 100.

An unbounded maxSegmentsInNodeLoadingQueue can cause cluster instability.
Since this is the default druid operators need to run into this instability
and then look through the docs to see that the recommended value for a large
cluster is 1000. This change makes it so the default will prevent clusters
from falling over as they grow over time.

DruidInputSource: Fix issues in column projection, timestamp handling. (#10267)
* DruidInputSource: Fix issues in column projection, timestamp handling.

DruidInputSource, DruidSegmentReader changes:

1) Remove "dimensions" and "metrics". They are not necessary, because we
   can compute which columns we need to read based on what is going to
   be used by the timestamp, transform, dimensions, and metrics.
2) Start using ColumnsFilter (see below) to decide which columns we need
   to read.
3) Actually respect the "timestampSpec". Previously, it was ignored, and
   the timestamp of the returned InputRows was set to the `__time` column
   of the input datasource.

(1) and (2) together fix a bug in which the DruidInputSource would not
properly read columns that are used as inputs to a transformSpec.

(3) fixes a bug where the timestampSpec would be ignored if you attempted
to set the column to something other than `__time`.

(1) and (3) are breaking changes.

Web console changes:

1) Remove "Dimensions" and "Metrics" from the Druid input source.
2) Set timestampSpec to `{"column": "__time", "format": "millis"}` for
   compatibility with the new behavior.

Other changes:

1) Add ColumnsFilter, a new class that allows input readers to determine
   which columns they need to read. Currently, it's only used by the
   DruidInputSource, but it could be used by other columnar input sources
   in the future.
2) Add a ColumnsFilter to InputRowSchema.
3) Remove the metric names from InputRowSchema (they were unused).
4) Add InputRowSchemas.fromDataSchema method that computes the proper
   ColumnsFilter for given timestamp, dimensions, transform, and metrics.
5) Add "getRequiredColumns" method to TransformSpec to support the above.

* Various fixups.

* Uncomment incorrectly commented lines.

* Move TransformSpecTest to the proper module.

* Add druid.indexer.task.ignoreTimestampSpecForDruidInputSource setting.

* Fix.

* Fix build.

* Checkstyle.

Add dynamic coordinator config that allows control over how many segments are considered when picking a segment to move. (#10284)
* dynamic coord config adding more balancing control

add new dynamic coordinator config, maxSegmentsToConsiderPerMove. This
config caps the number of segments that are iterated over when selecting
a segment to move. The default value combined with current balancing
strategies will still iterate over all provided segments. However,
setting this value to something > 0 will cap the number of segments
visited. This could make sense in cases where a cluster has a very large
number of segments and the admins prefer less iterations vs a thorough
consideration of all segments provided.

* fix checkstyle failure

Filter http requests by http method (#10085)
* Filter http requests by http method

Add a config that allows a user which http methods to allow against their
Druid server.

Druid will only accept http requests with the method: GET, PUT, POST, DELETE
and OPTIONS.
If a Druid admin wants to allow other methods, they can do so by using the
ServerConfig#allowedHttpMethods config.

If a Druid user would like to disallow OPTIONS, this can be done by changing
the AuthConfig#allowUnauthenticatedHttpOptions config

* Exclude OPTIONS from always supported HTTP methods

datasources you can use, and has examples for both SQL and native.
- New doc: querying/query-execution.md describes how native queries
are executed at a high level. It doesn't go into the details of specific
query engines or how queries run at a per-segment level. But I think it
would be good to add or link that content here in the future.
- Refreshed doc: querying/sql.md updated to refer to joins, reformatted
a bit, added a new "Query translation" section that explains how
queries are translated from SQL to native, and removed configuration
details (moved to configuration/index.md).
- Refreshed doc: querying/joins.md updated to refer to join datasources.

Smaller changes:

- Add helpful banners to the top of query documentation pages telling
people whether a given page describes SQL, native, or both.
- Add SQL metrics to operations/metrics.md.
- Add some color and cross-links in various places.
- Add native query component docs to the sidebar, and renamed them so
they look nicer.
- Remove Select query from the sidebar.
- Fix Broker SQL configs in configuration/index.md. Remove them from
querying/sql.md.
- Combined querying/searchquery.md and querying/searchqueryspec.md.

SQL support for joins on subqueries. (#9545)
* SQL support for joins on subqueries.

Changes to SQL module:

- DruidJoinRule: Allow joins on subqueries (left/right are no longer
  required to be scans or mappings).
- DruidJoinRel: Add cost estimation code for joins on subqueries.
- DruidSemiJoinRule, DruidSemiJoinRel: Removed, since DruidJoinRule can
  handle this case now.
- DruidRel: Remove Nullable annotation from toDruidQuery, because
  it is no longer needed (it was used by DruidSemiJoinRel).
- Update Rules constants to reflect new rules available in our current
  version of Calcite. Some of these are useful for optimizing joins on
  subqueries.
- Rework cost estimation to be in terms of cost per row, and place all
  relevant constants in CostEstimates.

Other changes:

- RowBasedColumnSelectorFactory: Don't set hasMultipleValues. The lack
  of isComplete is enough to let callers know that columns might have
  multiple values, and explicitly setting it to true causes
  ExpressionSelectors to think it definitely has multiple values, and
  treat the inputs as arrays. This behavior interfered with some of the
  new tests that involved queries on lookups.
- QueryContexts: Add maxSubqueryRows parameter, and use it in druid-sql
  tests.
