* Update execution-submit-dialog for file input support
Modified the execution-submit-dialog to support file inputs instead of text inputs for better usability. Users can now submit their queries by selecting a JSON file directly or dragging the file into the dialog. Made appropriate UI adjustments to accommodate this change in execution-submit-dialog styles file.

I was looking into adding a rule to do this, and found that it was already
happening as part of Calcite's RexSimplify. So this patch simply adds some
tests to ensure that it continues to happen.
Add class PasswordHashGenerator. Move hashing logic from BasicAuthUtils to this new class.
Add cache in the hash generator to contain the computed hash of passwords and boost validator performance
Cache has max size 1000 and expiry 1 hour
Key of the cache is an SHA-256 hash of the (password + random salt generated on service startup)
This PR fixes a bug with the long string pair serde where null and empty strings are treated equivalently, and the return value is always null. When 'useDefaultValueForNull' was set to true by default, this wasn't a commonly seen issue, because nulls were equivalent to empty strings. However, since the default has changed to false, this can create incorrect results when the long string pairs are serded, where the empty strings are incorrectly converted to nulls.
Currently, If 2 tasks are consuming from the same partitions, try to publish the segment and update the metadata, the second task can fail because the end offset stored in the metadata store doesn't match with the start offset of the second task. We can fix this by retrying instead of failing.
AFAIK apart from the above issue, the metadata mismatch can happen in 2 scenarios:
- when we update the input topic name for the data source
- when we run 2 replicas of ingestion tasks(1 replica will publish and 1 will fail as the first replica has already updated the metadata).
Implemented the comparable function to compare the last committed end offset and new Sequence start offset. And return a specific error msg for this.
Add retry logic on indexers to retry for this specific error msg.
Updated the existing test case.
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.
Added support for Azure Government storage in Druid Azure-Extensions. This enhancement allows the Azure-Extensions to be compatible with different Azure storage types by updating the endpoint suffix from a hardcoded value to a configurable one.
This PR enables the flag by default to queue excess query requests in the jetty queue. Still keeping the flag so that it can be turned off if necessary. But the flag will be removed in the future.
changes:
* ColumnIndexSelector now extends ColumnSelector. The only real implementation of ColumnIndexSelector, ColumnSelectorColumnIndexSelector, already has a ColumnSelector, so this isn't very disruptive
* removed getColumnNames from ColumnSelector since it was not used
* VirtualColumns and VirtualColumn getIndexSupplier method now needs argument of ColumnIndexSelector instead of ColumnSelector, which allows expression virtual columns to correctly recognize other virtual columns, fixing an issue which would incorrectly handle other virtual columns as non-existent columns instead
* fixed a bug with sql planner incorrectly not using expression filter for equality filters on columns with extractionFn and no virtual column registry
Changes
- Audit create or update of a supervisor spec. The purpose of the audit is
to track which user made change to a supervisor and when.
- The audit entry does not contain the entire spec or even a diff of the changes
as this is already captured in the `druid_supervisors` metadata table.
* 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
This logic error causes sarg expansion to happen twice for IN or NOT IN points.
It doesn't affect the final generated native query, because the
redundant expansions gets combined. But it slows down planning, especially
for large NOT IN.

Description
When batchAllocationWaitTime is set to 0, the segment allocation queue is polled continuously even when it is empty. This would take up cpu cycles unnecessarily.
Some existing race conditions would also become more frequent when the batchAllocationWaitTime is 0. This PR tries to better address those race conditions as well.
Changes
Do not reschedule a poll if queue is empty
When a new batch is added to queue, schedule a poll
Simplify keyToBatch map
Handle race conditions better
As soon as a batch starts getting processed, do not add any more requests to it
FILTER_INTO_JOIN is mainly run along with the other rules with the Volcano planner; however if the query starts highly underdefined (join conditions in the where clauses) that generic query could give a lot of room for the other rules to play around with only enabled it for when the join uses subqueries for its inputs.
PROJECT_FILTER rule is not that useful. and could increase planning times by providing new plans. This problem worsened after we started supporting inner joins with arbitrary join conditions in https://github.com/apache/druid/pull/15302
- Rename ExprType to BaseType in CollectComparisons, since ExprType is a thing
that exists elsewhere.
- Remove unused "notInRexNodes" from SearchOperatorConversion.
* 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.
* New handling for COALESCE, SEARCH, and filter optimization.
COALESCE is converted by Calcite's parser to CASE, which is largely
counterproductive for us, because it ends up duplicating expressions.
In the current code we end up un-doing it in our CaseOperatorConversion.
This patch has a different approach:
1) Add CaseToCoalesceRule to convert CASE back to COALESCE earlier, before
the Volcano planner runs, using CaseToCoalesceRule.
2) Add FilterDecomposeCoalesceRule to decompose calls like
"f(COALESCE(x, y))" into "(x IS NOT NULL AND f(x)) OR (x IS NULL AND f(y))".
This helps use indexes when available on x and y.
3) Add CoalesceLookupRule to push COALESCE into the third arg of LOOKUP.
4) Add a native "coalesce" function so we can convert 3+ arg COALESCE.
The advantage of this approach is that by un-doing the CASE to COALESCE
conversion earlier, we have flexibility to do more stuff with
COALESCE (like decomposition and pushing into LOOKUP).
SEARCH is an operator used internally by Calcite to represent matching
an argument against some set of ranges. This patch improves our handling
of SEARCH in two ways:
1) Expand NOT points (point "holes" in the range set) from SEARCH as
`!(a || b)` rather than `!a && !b`, which makes it possible to convert
them to a "not" of "in" filter later.
2) Generate those nice conversions for NOT points even if the SEARCH
is not composed of 100% NOT points. Without this change, a SEARCH
for "x NOT IN ('a', 'b') AND x < 'm'" would get converted like
"x < 'a' OR (x > 'a' AND x < 'b') OR (x > 'b' AND x < 'm')".
One of the steps we take when generating Druid queries from Calcite
plans is to optimize native filters. This patch improves this step:
1) Extract common ANDed predicates in ConvertSelectorsToIns, so we can
convert "(a && x = 'b') || (a && x = 'c')" into "a && x IN ('b', 'c')".
2) Speed up CombineAndSimplifyBounds and ConvertSelectorsToIns on
ORs with lots of children by adjusting the logic to avoid calling
"indexOf" and "remove" on an ArrayList.
3) Refactor ConvertSelectorsToIns to reduce duplicated code between the
handling for "selector" and "equals" filters.
* Not so final.
* Fixes.
* Fix test.
* Fix test.
* Fix ColumnSelectorColumnIndexSelector#getColumnCapabilities.
It was using virtualColumns.getColumnCapabilities, which only returns
capabilities for virtual columns, not regular columns. The effect of this
is that expression filters (and in some cases, arrayContainsElement filters)
would build value matchers rather than use indexes.
I think this has been like this since #12315, which added the
getColumnCapabilities method to BitmapIndexSelector, and included the same
implementation as exists in the code today.
This error is easy to make due to the design of virtualColumns.getColumnCapabilities,
so to help avoid it in the future, this patch renames the method to
getColumnCapabilitiesWithoutFallback to emphasize that it does not return
capabilities for regular columns.
* Make getColumnCapabilitiesWithoutFallback package-private.
* Fix expression filter bitmap usage.
* Minor fixes
* Update docs/development/extensions-contrib/prometheus.md

* Allow empty inserts and replace.
- Introduce a new query context failOnEmptyInsert which defaults to false.
- When this context is false (default), MSQE will now allow empty inserts and replaces.
- When this context is true, MSQE will throw the existing InsertCannotBeEmpty MSQ fault.
- For REPLACE ALL over an ALL grain segment, the query will generate a tombstone spanning eternity
which will be removed eventually be the coordinator.
- Add unit tests in MSQInsertTest, MSQReplaceTest to test the new default behavior (i.e., when failOnEmptyInsert = false)
- Update unit tests in MSQFaultsTest to test the non-default behavior (i.e., when failOnEmptyInsert = true)
* Ignore test to see if it's the culprit for OOM
* Add heap dump config
* Bump up -Xmx from 1500 MB to 2048 MB
* Add steps to tarball and collect hprof dump to GHA action
* put back mx to 1500MB to trigger the failure
* add the step to reusable unit test workflow as well
* Revert the temp heap dump & @Ignore changes since max heap size is increased
* Minor updates
* Review comments
1. Doc suggestions
2. Add tests for empty insert and replace queries with ALL grain and limit in the
default failOnEmptyInsert mode (=false). Add similar tests to MSQFaultsTest with
failOnEmptyInsert = true, so the query does fail with an InsertCannotBeEmpty fault.
3. Nullable annotation and javadocs
* Add comment
replace_limit.patch
The PR: #13947 introduced a function evalDimension() in the interface RowFunction.
There was no default implementation added for this interface which causes all the implementations and custom transforms to fail and require to implement their own version of evalDimension method. This PR adds a default implementation in the interface which allows the evalDimension to return value as a Singleton array of eval result.
Currently in the realtime ingestion (Kafka/Kinesis) case, after publishing the segments, upon acknowledgement from the coordinator that the segments are already placed in some historicals, the peon would unannounce the segments (basically saying the segments are not in this peon anymore to the whole cluster) and drop the segments from cache and sink timeline in one shot.
The in transit queries from the brokers that still thinks the segments are in the peon can get a NullPointer exception when the peon is unsetting the hydrants in the sinks.
The fix would let the peon to wait for a configurable delay period before dropping segments, remove segments from cache etc after the peon unannounce the segments.
This delayed approach is similar to how the historicals handle segments moving out.
Database slowness while doing audits seems to be causing flakiness in auth ITs.
The failing test is almost always
`ITBasicAuthConfigurationTest.test_avaticaQuery_datasourceAndContextParamsUser`
but in some rare cases, other tests fail too. Alternately, this failing test has been seen to pass too.
It is most likely because the auth changes are not able to propagate in time from
the coordinator to other services.
Fix: Just log the audits rather than persisting them to database.
Most audits have been newly added and it is okay to not have them persisted.
Moreover, logging audits can also be more beneficial while debugging an IT.
Fixes#15072
Before this modification , the third parameter (timezone) require to be a Literal, it will throw a error when this parameter is column Identifier.
