* Excluding jackson-jaxrs dependency from ranger-plugin-common to address CVE regression introduced by ranger-upgrade: CVE-2019-10202, CVE-2019-10172
* remove the reference to outdated ranger 2.0 from the docs

Recent upgrade of ranger introduced CVE regressions due to outdated elasticsearch components.
Druid-ranger-plugin does not elasticsearch components , and they have been explicitly removed.
Update woodstox-core to 6.4.0 to address GHSA-3f7h-mf4q-vrm4
This PR revives #14978 with a few more bells and whistles. Instead of an unconditional cross-join, we will now split the join condition such that some conditions are now evaluated post-join. To decide what sub-condition goes where, I have refactored DruidJoinRule class to extract unsupported sub-conditions. We build a postJoinFilter out of these unsupported sub-conditions and push to the join.
* update confluent's dependencies to common, supported version
Update io.confluent.* dependencies to common, updated version 6.2.12
currently used versions are EOL
* move version definition to the top level pom
Changes:
- Fix log `Got end of partition marker for partition [%s] from task [%s] in discoverTasks`
by fixing order of args
- Simplify in-line classes by using lambda
- Update kill task message from `Task [%s] failed to respond to [set end offsets]
in a timely manner, killing task` to `Failed to set end offsets, killing task`
- Clean up tests
There is a problem with Quantiles sketches and KLL Quantiles sketches.
Queries using the histogram post-aggregator fail if:
- the sketch contains at least one value, and
- the values in the sketch are all equal, and
- the splitPoints argument is not passed to the post-aggregator, and
- the numBins argument is greater than 2 (or not specified, which
leads to the default of 10 being used)
In that case, the query fails and returns this error:
{
"error": "Unknown exception",
"errorClass": "org.apache.datasketches.common.SketchesArgumentException",
"host": null,
"errorCode": "legacyQueryException",
"persona": "OPERATOR",
"category": "RUNTIME_FAILURE",
"errorMessage": "Values must be unique, monotonically increasing and not NaN.",
"context": {
"host": null,
"errorClass": "org.apache.datasketches.common.SketchesArgumentException",
"legacyErrorCode": "Unknown exception"
}
}
This behaviour is undesirable, since the caller doesn't necessarily
know in advance whether the sketch has values that are diverse
enough. With this change, the post-aggregators return [N, 0, 0...]
instead of crashing, where N is the number of values in the sketch,
and the length of the list is equal to numBins. That is what they
already returned for numBins = 2.
Here is an example of a query that would fail:
{"queryType":"timeseries",
"dataSource": {
"type": "inline",
"columnNames": ["foo", "bar"],
"rows": [
["abc", 42.0],
["def", 42.0]
]
},
"intervals":["0000/3000"],
"granularity":"all",
"aggregations":[
{"name":"the_sketch", "fieldName":"bar", "type":"quantilesDoublesSketch"}],
"postAggregations":[
{"name":"the_histogram",
"type":"quantilesDoublesSketchToHistogram",
"field":{"type":"fieldAccess","fieldName":"the_sketch"},
"numBins": 3}]}
I believe this also fixes issue #10585.
* Fix capacity response in mm-less ingestion (#14888)
Changes:
- Fix capacity response in mm-less ingestion.
- Add field usedClusterCapacity to the GET /totalWorkerCapacity response.
This API should be used to get the total ingestion capacity on the overlord.
- Remove method `isK8sTaskRunner` from interface `TaskRunner`
* Using Map to perform comparison
* Minor Change

Saw bug where MSQ controller task would continue to hold the task slot even after cancel was issued.
This was due to a deadlock created on work launch. The main thread was waiting for tasks to spawn and the cancel thread was waiting for tasks to finish.
The fix was to instruct the MSQWorkerTaskLauncher thread to stop creating new tasks which would enable the main thread to unblock and release the slot.
Also short circuited the taskRetriable condition. Now the check is run in the MSQWorkerTaskLauncher thread as opposed to the main event thread loop. This will result in faster task failure in case the task is deemed to be non retriable.
* MSQ generates tombstones honoring the query's granularity.
This change tweaks to only account for the infinite-interval tombstones.
For finite-interval tombstones, the MSQ query granualrity will be used
which is consistent with how MSQ works.

* Fixed flaky test in S3DataSegmentPusherConfigTest.testSerializationValidatingMaxListingLength
* Minor Changes
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.
* Use filters for pruning properly for hash-joins.
Native used them too aggressively: it might use filters for the RHS
to prune the LHS. MSQ used them not at all. Now, both use them properly,
pruning based on base (LHS) columns only.
* Fix tests.
* Fix style.
* Clear filterFields too.
* Update.
* 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.
* better documentation for the differences between arrays and mvds
* add outputType to ExpressionPostAggregator to make docs true
* add output coercion if outputType is defined on ExpressionPostAgg
* updated post-aggregations.md to be consistent with aggregations.md and filters.md and use tables
While running queries on real time tasks using MSQ, there is an issue with queries with certain order by columns.
If the query specifies a non time column, the query is planned as it is supported by MSQ. However, this throws an exception when passed to real time tasks once as the native query stack does not support it. This PR resolves this by removing the ordering from the query before contacting real time tasks.
Fixes a bug with MSQ while reading data from real time tasks with non time ordering
ServiceClientImpl logs the cause of every retry, even though we are retrying the connection attempt. This leads to slight pollution in the logs because a lot of the time, the reason for retrying is the same. This is seen primarily in MSQ, when the worker task hasn't launched yet however controller attempts to connect to the worker task, which can lead to scary-looking messages (with INFO log level), even though they are normal.
This PR changes the logging logic to log every 10 (arbitrary number) retries instead of every retry, to reduce the pollution of the logs.
Note: If there are no retries left, the client returns an exception, which would get thrown up by the caller, and therefore this change doesn't hide any important information.
Functions that accept literals also allow casted literals. This shouldn't have an impact on the queries that the user writes. It enables the SQL functions to accept explicit cast, which is required with JDBC.
* Update S3 retry logic based on the underlying cause in case of IOException.
4xx and other errors wrapped in IOException for instance aren't retriable.
* Fix CI

Patch adds an undocumented parameter taskLockType to MSQ so that we can start enabling this feature for users who are interested in testing the new lock types.
This PR addresses a bug with waiting for segments to be loaded. In the case of append, segments would be created with the same version. This caused the number of segments returned to be incorrect.
This PR changes this to keep track of the range of partition numbers as well for each version, which lets the task wait for the correct set of segments. The partition numbers are expected to be continuous since the task obtains the lock for the segment while running.
Adding the ability to limit the pages sizes of select queries.
We piggyback on the same machinery that is used to control the numRowsPerSegment.
This patch introduces a new context parameter rowsPerPage for which the default value is set to 100000 rows.
This patch also optimizes adding the last selectResults stage only when the previous stages have sorted outputs. Currently for each select query with selectDestination=durableStorage, we used to add this extra selectResults stage.

MSQ uses the string dimension schema for ARRAY<STRING> typed columns, which creates MVDs instead of string arrays as required. Therefore someone trying to ingest columns of type ARRAY<STRING> from an external data source or another data source would get STRING columns in the newly generated segments.
This patch changes the following:
- Use auto dimension schema to ingest the ARRAY<STRING> columns, which will create columns with the desired type.
- Add an undocumented flag ingestStringArraysAsMVDs to preserve the legacy behavior. Legacy behaviour is turned on by default.
- Create MSQArraysInsertTest and refactor some of the tests in MSQInsertTest.
* add a bunch of tests with array typed columns to CalciteArraysQueryTest
* fix a bug with unnest filter pushdown when filtering on unnested array columns
This PR aims to add the capabilities to:
1. Fetch the realtime segment metadata from the coordinator server view,
2. Adds the ability for workers to query indexers, similar to how brokers do the same for native queries.
Instead of passing the constants around in a new parameter; InputAccessor was introduced to take care of transparently handling the constants - this new class started picking up some copy-paste debris around field accesses; and made them a little bit more readble.
The sql standard is not very restrictive regarding this:
If AVG is specified and DT is exact numeric, then the declared type of the result is an implemen-
tation-defined exact numeric type with precision not less than the precision of DT and scale not
less than the scale of DT.
so; using the same type is also ok (without patch);
however the avg of 0 and 1 is 0 right now because of the retention of the integer typ
Postgres,MySql and Oracle and Drill seem to increase precision ; mssql returns 0
http://sqlfiddle.com/#!9/6f7248/1
I think we should also increase precision as its already calculated more precisely
Add segmentLoadWait as a query context parameter. If this is true, the controller queries the broker and waits till the segments created (if any) have been loaded by the load rules. The controller also provides this information in the live reports and task reports. If this is false, the controller exits immediately after finishing the query.
Row-based frames, and by extension, MSQ now supports numeric array types. This means that all queries consuming or producing arrays would also work with MSQ. Numeric arrays can also be ingested via MSQ. Post this patch, queries like, SELECT [1, 2] would work with MSQ since they consume a numeric array, instead of failing with an unsupported column type exception.
This patch introduces "processor managers" to processor factories, as a replacement for the sequence of processors. Processor managers can use the results of earlier processors to influence the creation of later processors, which provides us with the building block we need to ensure that broadcast join data is only read once.
In particular, when broadcast join is happening, the BaseFrameProcessorFactory now uses a ChainedProcessorManager to first run BroadcastJoinSegmentMapFnProcessor (in a single thread), and then run all of the regular processors (possibly multithreaded).
This change updates dependencies as needed and fixes tests to remove code incompatible with Java 21
As a result all unit tests now pass with Java 21.
* update maven-shade-plugin to 3.5.0 and follow-up to #15042
* explain why we need to override configuration when specifying outputFile
* remove configuration from dependency management in favor of explicit overrides in each module.
* update to mockito to 5.5.0 for Java 21 support when running with Java 11+
* continue using latest mockito 4.x (4.11.0) when running with Java 8
* remove need to mock private fields
* exclude incorrectly declared mockito dependency from pac4j-oidc
* remove mocking of ByteBuffer, since sealed classes can no longer be mocked in Java 21
* add JVM options workaround for system-rules junit plugin not supporting Java 18+
* exclude older versions of byte-buddy from assertj-core
* fix for Java 19 changes in floating point string representation
* fix missing InitializedNullHandlingTest
* update easymock to 5.2.0 for Java 21 compatibility
* update animal-sniffer-plugin to 1.23
* update nl.jqno.equalsverifier to 3.15.1
* update exec-maven-plugin to 3.1.0
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 maven shade plugin to try to fix build failures
Sometimes we get maven shade errors in our integ tests becasue we don't run clean in between runs to clear the cache in order to speed them up. This can lead to the below error.
Error: Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:3.2.4:shade (opentelemetry-extension) on project opentelemetry-emitter: Error creating shaded jar: duplicate entry: META-INF/services/org.apache.druid.opentelemetry.shaded.io.grpc.NameResolverProvider
See: https://issues.apache.org/jira/projects/MSHADE/issues/MSHADE-425?filter=allissues
An example run that failed: https://github.com/apache/druid/actions/runs/6301662092/job/17117142375?pr=14887
According to the ticket this is fixed by updating shade to 3.4.1.
When I updated to 3.4.1 I kept running into a different issue during static checks. (Caused by: java.lang.NoClassDefFoundError: com/github/rvesse/airline/parser/errors/ParseException)
I had to add the createDependencyReducedPom: false to get the build to pass.
The dependency reduced pom feature was added in 3.3.0 which we were not using before so setting it explicitly to false should not be a issue. https://issues.apache.org/jira/browse/MSHADE-36)
The aggregators had incorrect types for getResultType when shouldFinalze
is false. They had the finalized type, but they should have had the
intermediate type.
Also includes a refactor of how ExprMacroTable is handled in tests, to make
it easier to add tests for this to the MSQ module. The bug was originally
noticed because the incorrect result types caused MSQ queries with DS_HLL
to behave erratically.
* Remove stale comment since we're on avro version 1.11.1
* Update exception blocks. With 1.11.1, read() only throws IOException.
* Unit tests
* Cleanup and add more tests.
This entails:
Removing the enableUnnest flag and additional machinery
Updating the datasource plan and frame processors to support unnest
Adding support in MSQ for UnnestDataSource and FilteredDataSource
CalciteArrayTest now has a MSQ test component
Additional tests for Unnest on MSQ
With PR #14322 , MSQ insert/Replace q's will wait for segment to be loaded on the historical's before finishing.
The patch introduces a bug where in the main thread had a thread.sleep() which could not be interrupted via the cancel calls from the overlord.
This new patch addressed that problem by moving the thread.sleep inside a thread of its own. Thus the main thread is now waiting on the future object of this execution.
The cancel call can now shutdown the executor service via another method thus unblocking the main thread to proceed.
This commit pulls out some changes from #14407 to simplify that PR.
Changes:
- Rename `IndexerMetadataStorageCoordinator.announceHistoricalSegments` to `commitSegments`
- Rename the overloaded method to `commitSegmentsAndMetadata`
- Fix some typos
Currently, only the user who has submitted the async query has permission to interact with the status APIs for that async query. However, often we want an administrator to interact with these resources as well.
Druid handles these with the STATE resource traditionally, and if the requesting user has necessary permissions on it as well, alternatively, they should be allowed to interact with the status APIs, irrespective of whether they are the submitter of the query.
* Add IS [NOT] DISTINCT FROM to SQL and join matchers.
Changes:
1) Add "isdistinctfrom" and "notdistinctfrom" native expressions.
2) Add "IS [NOT] DISTINCT FROM" to SQL. It uses the new native expressions
when generating expressions, and is treated the same as equals and
not-equals when generating native filters on literals.
3) Update join matchers to have an "includeNull" parameter that determines
whether we are operating in "equals" mode or "is not distinct from"
mode.
* Main changes:
- Add ARRAY handling to "notdistinctfrom" and "isdistinctfrom".
- Include null in pushed-down filters when using "notdistinctfrom" in a join.
Other changes:
- Adjust join filter analyzer to more explicitly use InDimFilter's ValuesSets,
relying less on remembering to get it right to avoid copies.
* Remove unused "wrap" method.
* Fixes.
* Remove methods we do not need.
* Fix bug with INPUT_REF.
* SQL: Plan non-equijoin conditions as cross join followed by filter.
Druid has previously refused to execute joins with non-equality-based
conditions. This was well-intentioned: the idea was to push people to
write their queries in a different, hopefully more performant way.
But as we're moving towards fuller SQL support, it makes more sense to
allow these conditions to go through with the best plan we can come up
with: a cross join followed by a filter. In some cases this will allow
the query to run, and people will be happy with that. In other cases,
it will run into resource limits during execution. But we should at
least give the query a chance.
This patch also updates the documentation to explain how people can
tell whether their queries are being planned this way.
* cartesian is a word.
* Adjust tests.
* Update docs/querying/datasource.md

Currently, after an MSQ query, the web console is responsible for waiting for the segments to load. It does so by checking if there are any segments loading into the datasource ingested into, which can cause some issues, like in cases where the segments would never be loaded, or would end up waiting for other ingests as well.
This PR shifts this responsibility to the controller, which would have the list of segments created.
Changes:
- Make ServiceMetricEvent.Builder extend ServiceEventBuilder<ServiceMetricEvent>
and thus convert it to a plain builder rather than a builder of builder.
- Add methods setCreatedTime , setMetricAndValue to the builder
There is a current issue due to inconsistent metadata between worker and controller in MSQ. A controller can receive one set of segments, which are then marked as unused by, say, a compaction job. The worker would be unable to get the segment information as MetadataResource.
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.
Latest version of google-client-api is incompatible with the existing Guava version. This PR unblocks Update google client apis to latest version #14414
This PR adds a way to store the topic name in a column. Such a column can be used to distinguish messages coming from different topics in multi-topic ingestion.
Motivation:
- There is no usage of the `SegmentTransactionInsertAction` which passes a
non-null non-empty value of `segmentsToBeDropped`.
- This is not really needed either as overshadowed segments are marked as unused
by the Coordinator and need not be done in the same transaction as committing segments.
- It will also help simplify the changes being made in #14407
Changes:
- Remove `segmentsToBeDropped` from the task action and all intermediate methods
- Remove related tests which are not needed anymore
* Add supervisor /resetOffsets API.
- Add a new endpoint /druid/indexer/v1/supervisor/<supervisorId>/resetOffsets
which accepts DataSourceMetadata as a body parameter.
- Update logs, unit tests and docs.
* Add a new interface method for backwards compatibility.
* Rename
* Adjust tests and javadocs.
* Use CoreInjectorBuilder instead of deprecated makeInjectorWithModules
* UT fix
* Doc updates.
* remove extraneous debugging logs.
* Remove the boolean setting; only ResetHandle() and resetInternal()
* Relax constraints and add a new ResetOffsetsNotice; cleanup old logic.
* A separate ResetOffsetsNotice and some cleanup.
* Minor cleanup
* Add a check & test to verify that sequence numbers are only of type SeekableStreamEndSequenceNumbers
* Add unit tests for the no op implementations for test coverage
* CodeQL fix
* checkstyle from merge conflict
* Doc changes
* DOCUSAURUS code tabs fix. Thanks, Brian!
In this PR, I have gotten rid of multiTopic parameter and instead added a topicPattern parameter. Kafka supervisor will pass topicPattern or topic as the stream name to the core ingestion engine. There is validation to ensure that only one of topic or topicPattern will be set. This new setting is easier to understand than overloading the topic field that earlier could be interpreted differently depending on the value of some other field.
This PR adds support to read from multiple Kafka topics in the same supervisor. A multi-topic ingestion can be useful in scenarios where a cluster admin has no control over input streams. Different teams in an org may create different input topics that they can write the data to. However, the cluster admin wants all this data to be queryable in one data source.
* Update to Calcite 1.35.0
* Update from.ftl for Calcite 1.35.0.
* Fixed tests in Calcite upgrade by doing the following:
1. Added a new rule, CoreRules.PROJECT_FILTER_TRANSPOSE_WHOLE_PROJECT_EXPRESSIONS, to Base rules
2. Refactored the CorrelateUnnestRule
3. Updated CorrelateUnnestRel accordingly
4. Fixed a case with selector filters on the left where Calcite was eliding the virtual column
5. Additional test cases for fixes in 2,3,4
6. Update to StringListAggregator to fail a query if separators are not propagated appropriately
* Refactored for testcases to pass after the upgrade, introduced 2 new data sources for handling filters and select projects
* Added a literalSqlAggregator as the upgraded Calcite involved changes to subquery remove rule. This corrected plans for 2 queries with joins and subqueries by replacing an useless literal dimension with a post agg. Additionally a test with COUNT DISTINCT and FILTER which was failing with Calcite 1.21 is added here which passes with 1.35
* Updated to latest avatica and updated code as SqlUnknownTimeStamp is now used in Calcite which needs to be resolved to a timestamp literal
* Added a wrapper segment ref to use for unnest and filter segment reference
The Azure connector is introduced and MSQ's fault tolerance and durable storage can now be used with Microsoft Azure's blob storage. Also, the results of newly introduced queries from deep storage can now store and fetch the results from Azure's blob storage.
* Rolling supervior task publishing
* add an option for number of task groups to roll over
* better
* remove docs
* oops
* checkstyle
* wip test
* undo partial test change
* remove incomplete test
* 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.
