Add IS [NOT] TRUE, IS [NOT] FALSE native functions. (#14977)
They are not quite the same as "x == true", "x != true", etc. These
functions never return null, even when "x" itself is null.

Fix the uncaught exceptions when materializing results as frames (#14970)
When materializing the results as frames, we defer the creation of the frames in ScanQueryQueryToolChest, which passes through the catch-all block reserved for catching cases when we don't have the complete row signature in the query (and falls back to the old code).
This PR aims to resolve it by adding the frame generation code to the try-catch block we have at the outer level.

longer compatibility window for nested column format v4 (#14955)
changes:
* add back nested column v4 serializers
* 'json' schema by default still uses the newer 'nested common format' used by 'auto', but now has an optional 'formatVersion' property which can be specified to override format versions on native ingest jobs
* add system config to specify default column format stuff, 'druid.indexing.formats', and property 'druid.indexing.formats.nestedColumnFormatVersion' to specify system level preferred nested column format for friendly rolling upgrades from versions which do not support the newer 'nested common format' used by 'auto'

Calcite upgrade 1.35 (#14510)
* 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

fix nested field virtual column array column element vector object selector (#14729)
Fixes a case I missed in #14688 when the return type is STRING but its coming from a top level array typed column instead of a nested array column while making a vector object selector.

Also while here I noticed that the internal JSON_VALUE functions for array types were named inconsistently with the non-array functions, so I renamed them. These are not documented so it should not be disruptive in any way, since they are only used internally for rewrites while planning to make the correctly virtual column.

JSON_VALUE_RETURNING_ARRAY_VARCHAR -> JSON_VALUE_ARRAY_VARCHAR
JSON_VALUE_RETURNING_ARRAY_BIGINT -> JSON_VALUE_ARRAY_BIGINT
JSON_VALUE_RETURNING_ARRAY_DOUBLE -> JSON_VALUE_ARRAY_DOUBLE
The internal non-array functions are JSON_VALUE_VARCHAR, JSON_VALUE_BIGINT, and JSON_VALUE_DOUBLE.

Use OverlordClient for all Overlord RPCs. (#14581)
* Use OverlordClient for all Overlord RPCs.

Continuing the work from #12696, this patch removes HttpIndexingServiceClient
and the IndexingService flavor of DruidLeaderClient completely. All remaining
usages are migrated to OverlordClient.

Supporting changes include:

1) Add a variety of methods to OverlordClient.

2) Update MetadataTaskStorage to skip the complete-task lookup when
   the caller requests zero completed tasks. This helps performance of
   the "get active tasks" APIs, which don't want to see complete ones.

* Use less forbidden APIs.

* Fixes from CI.

* Add test coverage.

* Two more tests.

* Fix test.

* Updates from CR.

* Remove unthrown exceptions.

* Refactor to improve testability and test coverage.

* Add isNil tests.

* Remove unnecessary "deserialize" methods.

Simplify bounds/range vs selectors/equality logic in SQL planning. (#14619)
* Simplify bounds/range vs selectors/equality logic in SQL planning.

1) Consolidate duplicate code related to Expressions#buildTimeFloorFilter.

2) Cleaner logic in Expressions#toSimpleLeafFilter: choose bounds vs range
   filter based solely on plannerContext.isUseBoundsAndSelectors, not also
   considering rhs kind. Use parsed rhs in both paths (except for numerics
   in the bound path).

3) Fix ArrayContains, ArrayOverlap to avoid equality filters when there is
   an extractionFn present. Fixes a bug introduced in #14612.

* Avoid sending nonprimitives down the bound path.

Add `aggregatorMergeStrategy` property in SegmentMetadata queries (#14560)
* Add aggregatorMergeStrategy property to SegmentMetadaQuery.

- Adds a new property aggregatorMergeStrategy to segmentMetadata query.
aggregatorMergeStrategy currently supports three types of merge strategies -
the legacy strict and lenient strategies, and the new latest strategy.
- The latest strategy considers the latest aggregator from the latest segment
by time order when there's a conflict when merging aggregators from different
segments.
- Deprecate lenientAggregatorMerge property; The API validates that both the new
and old properties are not set, and returns an exception.
- When merging segments as part of segmentMetadata query, the segments have a more
elaborate id -- <datasource>_<interval>_merged_<partition_number> format, similar to
the name format that segments usually contain. Previously it was simply "merged".
- Adjust unit tests to test the latest strategy, to assert the returned complete
SegmentAnalysis object instead of just the aggregators for completeness.

* Don't explicitly set strict strategy in tests

* Apply suggestions from code review

Co-authored-by: Katya Macedo  <38017980+ektravel@users.noreply.github.com>

Fix ColumnSignature error message and jdk17 test issue. (#14538)
* Fix ColumnSignature error message and jdk17 test issue.

On jdk17, the "problem" part of the error message could change from
NullPointerException to:

  Cannot invoke "String.length()" because "s" is null

Due to the new more-helpful NPEs in Java 17. This broke the expectation
and led to test failures on this case.

This patch fixes the problem by improving the error message so it isn't
a generic NullPointerException.

Main changes:

1) Cache parsed and analyzed expressions within PlannerContext for a

This speeds up SQL planning, because SQL planning involves parsing
analyzing the same expression strings over and over again.

SQL OperatorConversions: Introduce.aggregatorBuilder, allow CAST-as-literal. (#14249)
* SQL OperatorConversions: Introduce.aggregatorBuilder, allow CAST-as-literal.

Four main changes:

1) Provide aggregatorBuilder, a more consistent way of defining the
   SqlAggFunction we need for all of our SQL aggregators. The mechanism
   is analogous to the one we already use for SQL functions
   (OperatorConversions.operatorBuilder).

2) Allow CASTs of constants to be considered as "literalOperands". This
   fixes an issue where various of our operators are defined with
   OperandTypes.LITERAL as part of their checkers, which doesn't allow
   casts. However, in these cases we generally _do_ want to allow casts.
   The important piece is that the value must be reducible to a constant,
   not that the SQL text is literally a literal.

3) Update DataSketches SQL aggregators to use the new aggregatorBuilder
   functionality. The main user-visible effect here is [2]: the aggregators
   would now accept, for example, "CAST(0.99 AS DOUBLE)" as a literal
   argument. Other aggregators could be updated in a future patch.

4) Rename "requiredOperands" to "requiredOperandCount", because the
   old name was confusing. (It rhymes with "literalOperands" but the
   arguments mean different things.)

* Adjust method calls.

Decouple logical planning and native query generation in SQL planning (#14232)
Add a new planning strategy that explicitly decouples the DAG from building the native query.

With this mode, it is Calcite's job to generate a "logical DAG" which is all of the various
DruidProject, DruidFilter, etc. nodes.  We then take those nodes and use them to build a native
query.  The current commit doesn't pass all tests, but it does work for some things and is a
decent starting baseline.

Errors take 3 (#14004)
Introduce DruidException, an exception whose goal in life is to be delivered to a user.

DruidException itself has javadoc on it to describe how it should be used.  This commit both introduces the Exception and adjusts some of the places that are generating exceptions to generate DruidException objects instead, as a way to show how the Exception should be used.

This work was a 3rd iteration on top of work that was started by Paul Rogers.  I don't know if his name will survive the squash-and-merge, so I'm calling it out here and thanking him for starting on this.

Add column replication_factor column to sys.segments table (#14403)
Description:
Druid allows a configuration of load rules that may cause a used segment to not be loaded
on any historical. This status is not tracked in the sys.segments table on the broker, which
makes it difficult to determine if the unavailability of a segment is expected and if we should
not wait for it to be loaded on a server after ingestion has finished.

Changes:
- Track replication factor in `SegmentReplicantLookup` during evaluation of load rules
- Update API `/druid/coordinator/v1metadata/segments` to return replication factor
- Add column `replication_factor` to the sys.segments virtual table and populate it in
`MetadataSegmentView`
- If this column is 0, the segment is not assigned to any historical and will not be loaded.

add configurable ColumnTypeMergePolicy to SegmentMetadataCache (#14319)
This PR adds a new interface to control how SegmentMetadataCache chooses ColumnType when faced with differences between segments for SQL schemas which are computed, exposed as druid.sql.planner.metadataColumnTypeMergePolicy and adds a new 'least restrictive type' mode to allow choosing the type that data across all segments can best be coerced into and sets this as the default behavior.

This is a behavior change around when segment driven schema migrations take effect for the SQL schema. With latestInterval, the SQL schema will be updated as soon as the first job with the new schema has published segments, while using leastRestrictive, the schema will only be updated once all segments are reindexed to the new type. The benefit of leastRestrictive is that it eliminates a bunch of type coercion errors that can happen in SQL when types are varied across segments with latestInterval because the newest type is not able to correctly represent older data, such as if the segments have a mix of ARRAY and number types, or any other combinations that lead to odd query plans.

MSQ: Subclass CalciteJoinQueryTest, other supporting changes. (#14105)
* MSQ: Subclass CalciteJoinQueryTest, other supporting changes.

The main change is the new tests: we now subclass CalciteJoinQueryTest
in CalciteSelectJoinQueryMSQTest twice, once for Broadcast and once for
SortMerge.

Two supporting production changes for default-value mode:

1) InputNumberDataSource is marked as concrete, to allow leftFilter to
   be pushed down to it.

2) In default-value mode, numeric frame field readers can now return nulls.
   This is necessary when stacking joins on top of joins: nulls must be
   preserved for semantics that match broadcast joins and native queries.

3) In default-value mode, StringFieldReader.isNull returns true on empty
   strings in addition to nulls. This is more consistent with the behavior
   of the selectors, which map empty strings to null as well in that mode.

As an effect of change (2), the InsertTimeNull change from #14020 (to
replace null timestamps with default timestamps) is reverted. IMO, this
is fine, as either behavior is defensible, and the change from #14020
hasn't been released yet.

* Adjust tests.

* Style fix.

* Additional tests.

SQL planning: Consider subqueries in fewer scenarios. (#14123)
* SQL planning: Consider subqueries in fewer scenarios.

Further adjusts logic in DruidRules that was previously adjusted in #13902.
The reason for the original change was that the comment "Subquery must be
a groupBy, so stage must be >= AGGREGATE" was no longer accurate. Subqueries
do not need to be groupBy anymore; they can really be any type of query.
If I recall correctly, the change was needed for certain window queries
to be able to plan on top of Scan queries.

However, this impacts performance negatively, because it causes many
additional outer-query scenarios to be considered, which is expensive.

So, this patch updates the matching logic to consider fewer scenarios. The
skipped scenarios are ones where we expect that, for one reason or another,
it isn't necessary to consider a subquery.

* Remove unnecessary escaping.

KillTask should return empty inputSource resources (#14106)
### Description

This pr fixes a few bugs found with the inputSource security feature.

1. `KillUnusedSegmentsTask` previously had no definition for the `getInputSourceResources`, which caused an unsupportedOperationException to be thrown when this task type was submitted with the inputSource security feature enabled. This task type should not require any input source specific resources, so returning an empty set for this task type now.

2. Fixed a bug where when the input source type security feature is enabled, all of the input source type specific resources used where authenticated against:

`{"resource": {"name": "EXTERNAL", "type": "{INPUT_SOURCE_TYPE}"}, "action": "READ"}`

When they should be instead authenticated against:

`{"resource": {"name": "{INPUT_SOURCE_TYPE}", "type": "EXTERNAL"}, "action": "READ"}`

3. fixed bug where supervisor tasks were not authenticated against the specific input source types used, if input source security feature was enabled.

Main changes:

2) Add InlineInputSpec, and modify of DataSourcePlan.forInline to use

   data to act as the right-hand side of a join, if needed.

Supporting changes:

1) Modify JoinDataSource's leftFilter validation to be a little less
   strict: it's now OK with leftFilter being attached to any concrete
   leaf (no children) datasource, rather than requiring it be a table.
   This allows MSQ to create JoinDataSource with InputNumberDataSource
   as the base.

   query lookups and inline data directly.

Fixes a bug where LongFieldWriter didn't write a properly transformed
zero when writing out a null. This had no meaningful effect in SQL-compatible
null handling mode, because the field would get treated as a null anyway.
But it does have an effect in default-value mode: it would cause Long.MIN_VALUE
to get read out instead of zero.

allowing reading of nullable frames by servers in default-value mode.

Allow for Input source security in native task layer (#14003)
Fixes #13837.

### Description

This change allows for input source type security in the native task layer.

To enable this feature, the user must set the following property to true:

`druid.auth.enableInputSourceSecurity=true`

The default value for this property is false, which will continue the existing functionality of needing authorization to write to the respective datasource.

When this config is enabled, the users will be required to be authorized for the following resource action, in addition to write permission on the respective datasource.

`new ResourceAction(new Resource(ResourceType.EXTERNAL, {INPUT_SOURCE_TYPE}, Action.READ`

where `{INPUT_SOURCE_TYPE}` is the type of the input source being used;, http, inline, s3, etc..

Only tasks that provide a non-default implementation of the `getInputSourceResources` method can be submitted when config `druid.auth.enableInputSourceSecurity=true` is set. Otherwise, a 400 error will be thrown.

Always use file sizes when determining batch ingest splits (#13955)
* Always use file sizes when determining batch ingest splits.

Main changes:

1) Update CloudObjectInputSource and its subclasses (S3, GCS,
   Azure, Aliyun OSS) to use SplitHintSpecs in all cases. Previously, they
   were only used for prefixes, not uris or objects.

2) Update ExternalInputSpecSlicer (MSQ) to consider file size. Previously,
   file size was ignored; all files were treated as equal weight when
   determining splits.

A side effect of these changes is that we'll make additional network
calls to find the sizes of objects when users specify URIs or objects
as opposed to prefixes. IMO, this is worth it because it's the only way
to respect the user's split hint and task assignment settings.

Secondary changes:

1) S3, Aliyun OSS: Use getObjectMetadata instead of listObjects to get
   metadata for a single object. This is a simpler call that is also
   expected to be less expensive.

2) Azure: Fix a bug where getBlobLength did not populate blob
   reference attributes, and therefore would not actually retrieve the
   blob length.

3) MSQ: Align dynamic slicing logic between ExternalInputSpecSlicer and
   TableInputSpecSlicer.

4) MSQ: Adjust WorkerInputs to ensure there is always at least one
   worker, even if it has a nil slice.
