This parameter has been removed for awhile now as of Druid 0.23.0
https://github.com/apache/druid/pull/12187.
The code was only used in tests to verify that serialization works.
Now remove all references to avoid any confusion.
* Add native filter conversion for SCALAR_IN_ARRAY.
Main changes:
1) Add an implementation of "toDruidFilter" in ScalarInArrayOperatorConversion.
2) Split up Expressions.literalToDruidExpression into two functions, so the first
half (literalToExprEval) can be used by ScalarInArrayOperatorConversion to more
efficiently create the list of match values.
* Fix type in time arithmetic conversion.
* Test updates.
* Update test cases to use null instead of '' in default-value mode.
* Switch test from msqIncompatible to compatible with a different result.
* Update one more test.
* Fix test.
* Update tests.
* Use ExprEvalWrapper to differentiate between empty string and null.
* Fix tests some more.
* Fix test.
* Additional comment.
* Style adjustment.
* Fix tests.
* trueValue -> actualValue.
* Use different approach, DruidLiteral instead of ExprEvalWrapper.
* Revert changes in ArrayOfDoublesSketchSqlAggregatorTest.
* QueryableIndex: Close columns after failed vector cursor setup.
If anything fails while setting up a vector cursor, the prior code in
QueryableIndex would not close its ColumnCache and would therefore leak
columns. Columns often contain references to buffers that must be closed.
* Fix style.
* * add another catalog clustering columns unit test
* * dissallow clusterKeys with descending order
* * make more clear that clustering is re-written into ingest node
whether a catalog table or not
* * when partitionedBy is stored in catalog, user shouldnt need to specify
it in order to specify clustering
* * fix intellij inspection failure

Description:
All the streaming ingestion tasks for a given datasource share the same lock for a given interval.
Changing lock types in the supervisor can lead to segment allocation errors due to lock conflicts
for the new tasks while the older tasks are still running.
Fix:
Allow locks of different types (EXCLUSIVE, SHARED, APPEND, REPLACE) to co-exist if they have
the same interval and the same task group.
Changes:
- Rename `DataSegmentChangeRequestAndStatus` to `DataSegmentChangeResponse`
- Rename `SegmentLoadDropHandler.Status` to `SegmentChangeStatus`
- Remove method `CoordinatorRunStats.getSnapshotAndReset()` as it was used only in
load queue peon implementations. Using an atomic reference is much simpler.
- Remove `ServerTestHelper.MAPPER`. Use existing `TestHelper.makeJsonMapper()` instead.
* test scoped jdbc driver for druidtest:/// backed DruidAvaticaTestDriver
** DecoupledTestConfig is used inside the URI - this will make it possible to attach to existing things more easily
* DruidQuidemTestBase can be used to create module level set of quidem tests
* added quidem commands: !convertedPlan, !logicalPlan, !druidPlan, !nativePlan
** for these I've used some values of the Hook which was there in calcite
* there are some shortcuts with proxies(they are only used during testing) - we can probably remove those later
* MSQ controller: Support in-memory shuffles; towards JVM reuse.
This patch contains two controller changes that make progress towards a
lower-latency MSQ.
First, support for in-memory shuffles. The main feature of in-memory shuffles,
as far as the controller is concerned, is that they are not fully buffered. That
means that whenever a producer stage uses in-memory output, its consumer must run
concurrently. The controller determines which stages run concurrently, and when
they start and stop.
"Leapfrogging" allows any chain of sort-based stages to use in-memory shuffles
even if we can only run two stages at once. For example, in a linear chain of
stages 0 -> 1 -> 2 where all do sort-based shuffles, we can use in-memory shuffling
for each one while only running two at once. (When stage 1 is done reading input
and about to start writing its output, we can stop 0 and start 2.)
1) New OutputChannelMode enum attached to WorkOrders that tells workers
whether stage output should be in memory (MEMORY), or use local or durable
storage.
2) New logic in the ControllerQueryKernel to determine which stages can use
in-memory shuffling (ControllerUtils#computeStageGroups) and to launch them
at the appropriate time (ControllerQueryKernel#createNewKernels).
3) New "doneReadingInput" method on Controller (passed down to the stage kernels)
which allows stages to transition to POST_READING even if they are not
gathering statistics. This is important because it enables "leapfrogging"
for HASH_LOCAL_SORT shuffles, and for GLOBAL_SORT shuffles with 1 partition.
4) Moved result-reading from ControllerContext#writeReports to new QueryListener
interface, which ControllerImpl feeds results to row-by-row while the query
is still running. Important so we can read query results from the final
stage using an in-memory channel.
5) New class ControllerQueryKernelConfig holds configs that control kernel
behavior (such as whether to pipeline, maximum number of concurrent stages,
etc). Generated by the ControllerContext.
Second, a refactor towards running workers in persistent JVMs that are able to
cache data across queries. This is helpful because I believe we'll want to reuse
JVMs and cached data for latency reasons.
1) Move creation of WorkerManager and TableInputSpecSlicer to the
ControllerContext, rather than ControllerImpl. This allows managing workers and
work assignment differently when JVMs are reusable.
2) Lift the Controller Jersey resource out from ControllerChatHandler to a
reusable resource.
3) Move memory introspection to a MemoryIntrospector interface, and introduce
ControllerMemoryParameters that uses it. This makes it easier to run MSQ in
process types other than Indexer and Peon.
Both of these areas will have follow-ups that make similar changes on the
worker side.

This PR fixes the first and last vector aggregators and improves their readability. Following changes are introduced
The folding is broken in the vectorized versions. We consider time before checking the folded object.
If the numerical aggregator gets passed any other object type for some other reason (like String), then the aggregator considers it to be folded, even though it shouldn’t be. We should convert these objects to the desired type, and aggregate them properly.
The aggregators must properly use generics. This would minimize the ClassCastException issues that can happen with mixed segment types. We are unifying the string first/last aggregators with numeric versions as well.
The aggregators must aggregate null values (https://github.com/apache/druid/blob/master/processing/src/main/java/org/apache/druid/query/aggregation/first/StringFirstLastUtils.java#L55-L56 ). The aggregator should only ignore pairs with time == null, and not value == null
Time nullity is ignored when trying to vectorize the data.
String versions initialized with DateTimes.MIN that is equal to Long.MIN / 2. This can cause incorrect results in case the user enters a custom time column. NOTE: This is still present because it would require a larger refactor in all of the versions.
There is a difference in what users might expect from the results because the code flow is changed (for example, the direction of the for loops, etc), however, this will only change the results, and not the contract set by first/last aggregators, which is that if multiple values have the same timestamp, then any of them can get picked.
If the column is non-existent, the users might expect a change in the timestamp from DateTime.MAX to Long.MAX, because the code incorrectly used DateTime.MAX to initialize the aggregator, however, in case of a custom timestamp column, this might not be the case. The SQL query might be prohibited from using any Long since it requires a cast to the timestamp function that can fail, but AFAICT native queries don't have such limitations.
#16068 modified DimensionHandlerUtils to accept complex types to be dimensions. This had an unintended side effect of allowing complex types to be joined upon (which wasn't guarded explicitly, it doesn't work).
This PR modifies the IndexedTable to reject building the index on the complex types to prevent joining on complex types. The PR adds back the check in the same place, explicitly.

Changes:
- Add new config `lagAggregate` to `LagBasedAutoScalerConfig`
- Add field `aggregateForScaling` to `LagStats`
- Use the new field/config to determine which aggregate to use to compute lag
- Remove method `Supervisor.computeLagForAutoScaler()`
Changes:
- Add `LookupLoadingSpec` to support 3 modes of lookup loading: ALL, NONE, ONLY_REQUIRED
- Add method `Task.getLookupLoadingSpec()`
- Do not load any lookups for `KillUnusedSegmentsTask`
* Four changes to scalar_in_array as follow-ups to #16306:
1) Align behavior for `null` scalars to the behavior of the native `in` and `inType` filters: return `true` if the array itself contains null, else return `null`.
2) Rename the class to more closely match the function name.
3) Add a specialization for constant arrays, where we build a `HashSet`.
4) Use `castForEqualityComparison` to properly handle cross-type comparisons.
Additional tests verify comparisons between LONG and DOUBLE are now
handled properly.
* Fix spelling.
* Adjustments from review.
JSON parsing has this function "charsetFix" that fixes up strings
so they can round-trip through UTF-8 encoding without loss of
fidelity. It was originally introduced to fix a bug where strings
could be sorted, encoded, then decoded, and the resulting decoded
strings could end up no longer in sorted order (due to character
swaps during the encode operation).
The code has been in place for some time, and only applies to JSON.
I am not sure if it needs to apply to other formats; it's certainly
more difficult to get broken strings from other formats. It's easy
in JSON because you can write a JSON string like "foo\uD900".
At any rate, this patch does not revisit whether charsetFix should
be applied to all formats. It merely optimizes it for the JSON case.
The function works by using CharsetEncoder.canEncode, which is
a relatively slow method (just as expensive as actually encoding).
This patch adds a short-circuit to skip canEncode if all chars in
a string are in the basic multilingual plane (i.e. if no chars are
surrogates).
Changes:
1) Check for handoff of upgraded realtime segments.
2) Drop sink only when all associated realtime segments have been abandoned.
3) Delete pending segments upon commit to prevent unnecessary upgrades and
partition space exhaustion when a concurrent replace happens. This also prevents
potential data duplication.
4) Register pending segment upgrade only on those tasks to which the segment is associated.
I'm adding OIDC context to the AuthenticationResult returned by pac4j extension. I wanted to use this context as input in OpenPolicyAgent authorization. Since AuthenticationResult already accepts context as a parameter it felt okay to pass the profile attributes there.
Fixes a bug introduced in #16296, where the sketch might not be
initialized if get() is called without calling aggregate(). Also adds
a test for this case.
Issue: #14989
The initial step in optimizing segment metadata was to centralize the construction of datasource schema in the Coordinator (#14985). Thereafter, we addressed the problem of publishing schema for realtime segments (#15475). Subsequently, our goal is to eliminate the requirement for regularly executing queries to obtain segment schema information.
This is the final change which involves publishing segment schema for finalized segments from task and periodically polling them in the Coordinator.
