Fix Flakiness in KafkaEmitterTest (#15907)
* thrust of the fix to allow for the json values to be out of order

The existing problem is that toMap doesn't turn some values into json primitive
values, for example segmentMetadata just has DateTime objects for it's time in
the EventMap, but Alert event converts those into strings when calling toMap.
This creates an issue because when we check the emitted events the mapper
deserializing the string value for dateTime leaves it as a string in the
EventMap. So the question is do we alter the events toMap() to return string/map
version of objects or to make the expected events do a round trip of
eventMap -> string -> eventMap to turn everything into json primitives

* fix issue by making toMap events convert Objects into strings, or maps

* fix linting errors

* use method of using mapper to round trip expected data to make it have same type
as those of the events emitted

* remove unnecessary comment

Clean up kafka emitter tests, add more validations and code coverage. (#15878)
* Clean up kafka emitter tests a bit and add more validations.

The test wasn't validating what events were sent, but simply the dropped counters, which
aren't that useful.
Additionally, this module has fewer tests, so folks often run into code coverage issue
in this extension. Hopefully this change helps with that too.

* Change things to feed-based rather than topic-based.

* Another test for shared topic

* Switch to DruidException, add test dependencies and sad path config tests.

* missing test dependency

* minor renames.

* Add more tests - to test unknown events and drop when queue is full

Parallelize storage of incremental segments (#13982)
During ingestion, incremental segments are created in memory for the different time chunks and persisted to disk when certain thresholds are reached (max number of rows, max memory, incremental persist period etc). In the case where there are a lot of dimension and metrics (1000+) it was observed that the creation/serialization of incremental segment file format for persistence and persisting the file took a while and it was blocking ingestion of new data. This affected the real-time ingestion. This serialization and persistence can be parallelized across the different time chunks. This update aims to do that.

The patch adds a simple configuration parameter to the ingestion tuning configuration to specify number of persistence threads. The default value is 1 if it not specified which makes it the same as it is today.

Kinesis adaptive memory management (#15360)
### Description

Our Kinesis consumer works by using the [GetRecords API](https://docs.aws.amazon.com/kinesis/latest/APIReference/API_GetRecords.html) in some number of `fetchThreads`, each fetching some number of records (`recordsPerFetch`) and each inserting into a shared buffer that can hold a `recordBufferSize` number of records. The logic is described in our documentation at: https://druid.apache.org/docs/27.0.0/development/extensions-core/kinesis-ingestion/#determine-fetch-settings 

There is a problem with the logic that this pr fixes: the memory limits rely on a hard-coded “estimated record size” that is `10 KB` if `deaggregate: false` and `1 MB` if `deaggregate: true`. There have been cases where a supervisor had `deaggregate: true` set even though it wasn’t needed, leading to under-utilization of memory and poor ingestion performance.

Users don’t always know if their records are aggregated or not. Also, even if they could figure it out, it’s better to not have to. So we’d like to eliminate the `deaggregate` parameter, which means we need to do memory management more adaptively based on the actual record sizes.

We take advantage of the fact that GetRecords doesn’t return more than 10MB (https://docs.aws.amazon.com/streams/latest/dev/service-sizes-and-limits.html ):

This pr: 

eliminates `recordsPerFetch`, always use the max limit of 10000 records (the default limit if not set)

eliminate `deaggregate`, always have it true

cap `fetchThreads` to ensure that if each fetch returns the max (`10MB`) then we don't exceed our budget (`100MB` or `5% of heap`). In practice this means `fetchThreads` will never be more than `10`. Tasks usually don't have that many processors available to them anyway, so in practice I don't think this will change the number of threads for too many deployments

add `recordBufferSizeBytes` as a bytes-based limit rather than records-based limit for the shared queue. We do know the byte size of kinesis records by at this point. Default should be `100MB` or `10% of heap`, whichever is smaller.

add `maxBytesPerPoll` as a bytes-based limit for how much data we poll from shared buffer at a time. Default is `1000000` bytes.

deprecate `recordBufferSize`, use `recordBufferSizeBytes` instead. Warning is logged if `recordBufferSize` is specified

deprecate `maxRecordsPerPoll`, use `maxBytesPerPoll` instead. Warning is logged if maxRecordsPerPoll` is specified

Fixed issue that when the record buffer is full, the fetchRecords logic throws away the rest of the GetRecords result after `recordBufferOfferTimeout` and starts a new shard iterator. This seems excessively churny. Instead,  wait an unbounded amount of time for queue to stop being full. If the queue remains full, we’ll end up right back waiting for it after the restarted fetch.

There was also a call to `newQ::offer` without check in `filterBufferAndResetBackgroundFetch`, which seemed like it could cause data loss. Now checking return value here, and failing if false.

### Release Note

Kinesis ingestion memory tuning config has been greatly simplified, and a more adaptive approach is now taken for the configuration. Here is a summary of the changes made:

eliminates `recordsPerFetch`, always use the max limit of 10000 records (the default limit if not set)

eliminate `deaggregate`, always have it true

cap `fetchThreads` to ensure that if each fetch returns the max (`10MB`) then we don't exceed our budget (`100MB` or `5% of heap`). In practice this means `fetchThreads` will never be more than `10`. Tasks usually don't have that many processors available to them anyway, so in practice I don't think this will change the number of threads for too many deployments

add `recordBufferSizeBytes` as a bytes-based limit rather than records-based limit for the shared queue. We do know the byte size of kinesis records by at this point. Default should be `100MB` or `10% of heap`, whichever is smaller.

add `maxBytesPerPoll` as a bytes-based limit for how much data we poll from shared buffer at a time. Default is `1000000` bytes.

deprecate `recordBufferSize`, use `recordBufferSizeBytes` instead. Warning is logged if `recordBufferSize` is specified

deprecate `maxRecordsPerPoll`, use `maxBytesPerPoll` instead. Warning is logged if maxRecordsPerPoll` is specified

Kafka emitter wasn't given the correct number of threads. It should be 1 thread per scheduled task. (#15719)
This change intelligently provisions the correct number of threads per scheduled task. 1 for each event type, and 1 for logging the lost events.
This is a change to make this work. But in the future it would be worthwhile to make each task not be greedy and share threads so there isn't a need of a thread per task.

Eliminate Periodic Realtime Segment Metadata Queries: Task Now Publish Schema for Seamless Coordinator Updates (#15475)
The initial step in optimizing segment metadata was to centralize the construction of datasource schema in the Coordinator (#14985). Subsequently, our goal is to eliminate the requirement for regularly executing queries to obtain segment schema information. This task encompasses addressing both realtime and finalized segments.

This modification specifically addresses the issue with realtime segments. Tasks will now routinely communicate the schema for realtime segments during the segment announcement process. The Coordinator will identify the schema alongside the segment announcement and subsequently update the schema for realtime segments in the metadata cache.

overhaul DruidPredicateFactory to better handle 3VL (#15629)
* overhaul DruidPredicateFactory to better handle 3VL

fixes some bugs caused by some limitations of the original design of how DruidPredicateFactory interacts with 3-value logic. The primary impacted area was with how filters on values transformed with expressions or extractionFn which turn non-null values into nulls, which were not possible to be modelled with the 'isNullInputUnknown' method

changes:
* adds DruidObjectPredicate to specialize string, array, and object based predicates instead of using guava Predicate
* DruidPredicateFactory now uses DruidObjectPredicate
* introduces DruidPredicateMatch enum, which all predicates returned from DruidPredicateFactory now use instead of booleans to indicate match. This means DruidLongPredicate, DruidFloatPredicate, DruidDoublePredicate, and the newly added DruidObjectPredicate apply methods all now return DruidPredicateMatch. This allows matchers and indexes
* isNullInputUnknown has been removed from DruidPredicateFactory

* rename, fix test

* adjust

* style

* npe

* more test

* fix default value mode to not match new test

Reverse lookup fixes and enhancements. (#15611)
* Reverse lookup fixes and enhancements.

1) Add a "mayIncludeUnknown" parameter to DimFilter#optimize. This is important
   because otherwise the reverse-lookup optimization is done improperly when
   the "in" filter appears under a "not", and the lookup extractionFn may return
   null for some possible values of the filtered column. The "includeUnknown" test
   cases in InDimFilterTest illustrate the difference in behavior.

2) Enhance InDimFilter#optimizeLookup to handle "mayIncludeUnknown", and to be able
   to do a reverse lookup in a wider variety of cases.

3) Make "unapply" protected in LookupExtractor, and move callers to "unapplyAll".
   The main reason is that MapLookupExtractor, a common implementation, lacks a
   reverse mapping and therefore does a scan of the map for each call to "unapply".
   For performance sake these calls need to be batched.

* Remove optimize call from BloomDimFilter.

* Follow the law.

* Fix tests.

* Fix imports.

* Switch function.

* Fix tests.

* More tests.

unpin snakeyaml, add suppressions and licenses (#15549)
* unpin snakeyaml globally, add suppressions and licenses
* pin snakeyaml in the specific modules that require version 1.x, update licenses and owasp suppression

This removes the pin of the Snakeyaml introduced in:  https://github.com/apache/druid/pull/14519
After the updates of io.kubernetes.java-client and io.confluent.kafka-clients, the only uses of the Snakeyaml 1.x are:
- in test scope, transitive dependency of jackson-dataformat-yaml🫙2.12.7
- in compile scope in contrib extension druid-cassandra-storage
- in compile scope in it-tests. 

With the dependency version un-pinned, io.kubernetes.java-client and io.confluent.kafka-clients bring Snakeyaml versions 2.0 and 2.2, consequently allowing to build a Druid distribution without the contrib-extension and free of vulnerable Snakeyaml versions.

Bump Jedis version to 5.0.2 (#15344)
Currently, the redis-cache extension uses Jedis 2.9.0, which was released over seven years ago and is no longer listed in the official support matrix. This patch upgrades it to ensure the compatibility with the recent version of Redis and make future upgrades easier, including:

Upgrade Jedis to v5.0.2, the latest version at this writing, and address the API changes and dependency version mismatch.

Replace mock-jedis with jedis-mock, since the former has not been actively maintained any longer and not compatible with recent versions of Jedis.

Relocating Table Schema Building: Shifting from Brokers to Coordinator for Improved Efficiency (#14985)
In the current design, brokers query both data nodes and tasks to fetch the schema of the segments they serve. The table schema is then constructed by combining the schemas of all segments within a datasource. However, this approach leads to a high number of segment metadata queries during broker startup, resulting in slow startup times and various issues outlined in the design proposal.

To address these challenges, we propose centralizing the table schema management process within the coordinator. This change is the first step in that direction. In the new arrangement, the coordinator will take on the responsibility of querying both data nodes and tasks to fetch segment schema and subsequently building the table schema. Brokers will now simply query the Coordinator to fetch table schema. Importantly, brokers will still retain the capability to build table schemas if the need arises, ensuring both flexibility and resilience.

Allow casted literal values in SQL functions accepting literals (Part 2) (#15316) 2023-11-03 21:22:19 +05:30
Gian Merlino d87d92bc43
Add system fields to input sources. (#15276)
* Add system fields to input sources.

Main changes:

1) The SystemField enum defines system fields "__file_uri", "__file_path",
   and "__file_bucket". They are associated with each input entity.

2) The SystemFieldInputSource interface can be added to any InputSource
   to make it system-field-capable. It sets up serialization of a list
   of configured "systemFields" in the JSON form of the input source, and
   provides a method getSystemFieldValue for computing the value of each
   system field. Cloud object, HDFS, HTTP, and Local now have this.

* Fix various LocalInputSource calls.

* Fix style stuff.

* Fixups.

* Fix tests and coverage.

Use min of scheduler threads and server threads for subquery guardrails. (#15295)
* Use min of scheduler threads and server threads for subquery guardrails.

This allows more memory to be used for subqueries when the query scheduler
is configured to limit queries below the number of server threads. The patch
also refactors the code so SubqueryGuardrailHelper is provided by a Guice
Provider rather than being created by ClientQuerySegmentWalker, to achieve
better separation of concerns.

* Exclude provider from coverage.

Allow users to pass task payload via deep storage instead of environment variable (#14887)
This change is meant to fix a issue where passing too large of a task payload to the mm-less task runner will cause the peon to fail to startup because the payload is passed (compressed) as a environment variable (TASK_JSON). In linux systems the limit for a environment variable is commonly 128KB, for windows systems less than this. Setting a env variable longer than this results in a bunch of "Argument list too long" errors.

Upgrade guava version to 31.1-jre (#14767)
Currently, Druid is using Guava 16.0.1 version. This upgrade to 31.1-jre fixes the following issues.

CVE-2018-10237 (Unbounded memory allocation in Google Guava 11.0 through 24.x before 24.1.1 allows remote attackers to conduct denial of service attacks against servers that depend on this library and deserialize attacker-provided data because the AtomicDoubleArray class (when serialized with Java serialization) and the CompoundOrdering class (when serialized with GWT serialization) perform eager allocation without appropriate checks on what a client has sent and whether the data size is reasonable). We don't use Java or GWT serializations. Despite being false positive they're causing red security scans on Druid distribution.

Add sampling factor for DeterminePartitionsJob (#13840)
There are two type of DeterminePartitionsJob:
-  When the input data is not assume grouped, there may be duplicate rows.
In this case, two MR jobs are launched. The first one do group job to remove duplicate rows.
And a second one to perform global sorting to find lower and upper bound for target segments.
- When the input data is assume grouped, we only need to launch the global sorting
MR job to find lower and upper bound for segments.

Sampling strategy:
- If the input data is assume grouped, sample by random at the mapper side of the global sort mr job.
- If the input data is not assume grouped, sample at the mapper of the group job. Use hash on time
and all dimensions and mod by sampling factor to sample, don't use random method because there
may be duplicate rows.

Minimize PostAggregator computations (#14708)
* Minimize PostAggregator computations

Since a change back in 2014, the topN query has been computing
all PostAggregators on all intermediate responses from leaf nodes
to brokers.  This generates significant slow downs for queries
with relatively expensive PostAggregators.  This change rewrites
the query that is pushed down to only have the minimal set of
PostAggregators such that it is impossible for downstream
processing to do too much work.  The final PostAggregators are
applied at the very end.
