add NumericRangeIndex interface and BoundFilter support
changes:
* NumericRangeIndex interface, like LexicographicalRangeIndex but for numbers
* BoundFilter now uses NumericRangeIndex if comparator is numeric and there is no extractionFn
* NestedFieldLiteralColumnIndexSupplier.java now supports supplying NumericRangeIndex for single typed numeric nested literal columns
* better faster stronger and (ever so slightly) more understandable
* more tests, fix bug
* fix style
* Druid planner now makes only one pass through Calcite planner
Resolves the issue that required two parse/plan cycles: one
for validate, another for plan. Creates a clone of the Calcite
planner and validator to resolve the conflict that prevented
the merger.
* Fixes for the Avatica JDBC driver
Correctly implement regular and prepared statements
Correctly implement result sets
Fix race condition with contexts
Clarify when parameters are used
Prepare for single-pass through the planner
* Addressed review comments
* Addressed review comment
Some queries like `REPLACE INTO ... SELECT TIME_PARSE("__time") AS __time FROM ...`
fail at the Calcite layer because any column with name `__time` is considered to be of
type `SqlTypeName.TIMESTAMP`.
Changes:
- Modify `RowSignatures.toRelDataType()` so that the type of `__time` column
is determined by the RowSignature's type.
* Automatic sizing for GroupBy dictionary sizes.
Merging and selector dictionary sizes currently both default to 100MB.
This is not optimal, because it can lead to OOM on small servers and
insufficient resource utilization on larger servers. It also invites
end users to try to tune it when queries run out of dictionary space,
which can make things worse if the end user sets it to too high.
So, this patch:
- Adds automatic tuning for selector and merge dictionaries. Selectors
use up to 15% of the heap and merge buffers use up to 30% of the heap
(aggregate across all queries).
- Updates out-of-memory error messages to emphasize enabling disk
spilling vs. increasing memory parameters. With the memory parameters
automatically sized, it is more likely that an end user will get
benefit from enabling disk spilling.
- Removes the query context parameters that allow lowering of configured
dictionary sizes. These complicate the calculation, and I don't see a
reasonable use case for them.
* Adjust tests.
* Review adjustments.
* Additional comment.
* Remove unused import.
* Preserve column order in DruidSchema, SegmentMetadataQuery.
Instead of putting columns in alphabetical order. This is helpful
because it makes query order better match ingestion order. It also
allows tools, like the reindexing flow in the web console, to more
easily do follow-on ingestions using a column order that matches the
pre-existing column order.
We prefer the order from the latest segments. The logic takes all
columns from the latest segments in the order they appear, then adds
on columns from older segments after those.
* Additional test adjustments.
* Adjust imports.
* Frame format for data transfer and short-term storage.
As we move towards query execution plans that involve more transfer
of data between servers, it's important to have a data format that
provides for doing this more efficiently than the options available to
us today.
This patch adds:
- Columnar frames, which support fast querying.
- Row-based frames, which support fast sorting via memory comparison
and fast whole-row copies via memory copying.
- Frame files, a container format that can be stored on disk or
transferred between servers.
The idea is we should use row-based frames when data is expected to
be sorted, and columnar frames when data is expected to be queried.
The code in this patch is not used in production yet. Therefore, the
patch involves minimal changes outside of the org.apache.druid.frame
package. The main ones are adjustments to SqlBenchmark to add benchmarks
for queries on frames, and the addition of a "forEach" method to Sequence.
* Fixes based on tests, static analysis.
* Additional fixes.
* Skip DS mapping tests on JDK 14+
* Better JDK checking in tests.
* Fix imports.
* Additional comment.
* Adjustments from code review.
* Update test case.
* Add EIGHT_HOUR into possible list of Granularities.
* Add the missing definition.
* fix test.
* Fix another test.
* Stylecheck finally passed.

This commit contains the cleanup needed for the new integration test framework.
Changes:
- Fix log lines, misspellings, docs, etc.
- Allow the use of some of Druid's "JSON config" objects in tests
- Fix minor bug in `BaseNodeRoleWatcher`
SQL expressions such as those containing `MV_FILTER_ONLY` and `MV_FILTER_NONE`
are planned as specialized virtual columns instead of the default `expression`-type virtual columns.
This commit adds a new context parameter to force the `expression`-type virtual columns.
Changes
- Add query context param `forceExpressionVirtualColumns`
- Use context param to determine if specialized virtual columns should be used or not
- Moved some tests into `CalciteExplainQueryTest`
* Add TIME_IN_INTERVAL SQL operator.
The operator is implemented as a convertlet rather than an
OperatorConversion, because this allows it to be equivalent to using
the >= and < operators directly.
* SqlParserPos cannot be null here.
* Remove unused import.
* Doc updates.
* Add words to dictionary.
True, false, and null have different meanings: true/false mean "legacy"
and "not legacy"; null means use the default set by ScanQueryConfig.
So, we need to respect this in the JsonIgnore setup.
* Remove null and empty fields from native queries
* Test fixes
* Attempted IT fix.
* Revisions from review comments
* Build fixes resulting from changes suggested by reviews
* IT fix for changed segment size
Fixes an issue where sql query request logs do not include the default query context
values set via `druid.query.default.context.xyz` runtime properties.
# Change summary
* Inject `DefaultQueryConfig` into `SqlLifecycleFactory`
* Add params from `DefaultQueryConfig` to the query context in `SqlLifecycle`
# Description
- This change does not affect query execution. This is because the
`DefaultQueryConfig` was already being used in `QueryLifecycle`,
which is initialized when the SQL is translated to a native query.
- This also handles any potential use case where a context parameter should be
handled at the SQL stage itself.
RowBasedColumnSelectorFactory inherited strange behavior from
Rows.objectToStrings for nulls that appear in lists: instead of being
left as a null, it is replaced with the string "null". Some callers may
need compatibility with this strange behavior, but it should be opt-in.
Query-time call sites are changed to opt-out of this behavior, since it
is not consistent with query-time expectations. The IncrementalIndex
ingestion-time call site retains the old behavior, as this is traditionally
when Rows.objectToStrings would be used.
Description
Fixes a bug when running q's like
SELECT cntarray,
Count(*)
FROM (SELECT dim1,
dim2,
Array_agg(cnt) AS cntarray
FROM (SELECT dim1,
dim2,
dim3,
Count(*) AS cnt
FROM foo
GROUP BY 1,
2,
3)
GROUP BY 1,
2)
GROUP BY 1
This generates an error:
org.apache.druid.java.util.common.ISE: Unable to convert type [Ljava.lang.Object; to org.apache.druid.segment.data.ComparableList
at org.apache.druid.segment.DimensionHandlerUtils.convertToList(DimensionHandlerUtils.java:405) ~[druid-xx]
Because it's an array of numbers it looks like it does the convertToList call, which looks like:
@Nullable
public static ComparableList convertToList(Object obj)
{
if (obj == null) {
return null;
}
if (obj instanceof List) {
return new ComparableList((List) obj);
}
if (obj instanceof ComparableList) {
return (ComparableList) obj;
}
throw new ISE("Unable to convert type %s to %s", obj.getClass().getName(), ComparableList.class.getName());
}
I.e. it doesn't know about arrays. Added the array handling as part of this PR.
In the case that the clustered by is before the partitioned by for an sql query, the error message is a bit confusing.
insert into foo select * from bar clustered by dim1 partitioned by all
Error: SQL parse failed
Encountered "PARTITIONED" at line 1, column 88.

org.apache.calcite.sql.parser.SqlParseException
This is a bit confusing and adding a check could be added to throw a more user friendly message stating that the order should be reversed.
Add error message for incorrectly ordered clause in sql.
* Direct UTF-8 access for "in" filters.
Directly related:
1) InDimFilter: Store stored Strings (in ValuesSet) plus sorted UTF-8
ByteBuffers (in valuesUtf8). Use valuesUtf8 whenever possible. If
necessary, the input set is copied into a ValuesSet. Much logic is
simplified, because we always know what type the values set will be.
I think that there won't even be an efficiency loss in most cases.
InDimFilter is most frequently created by deserialization, and this
patch updates the JsonCreator constructor to deserialize
directly into a ValuesSet.
2) Add Utf8ValueSetIndex, which InDimFilter uses to avoid UTF-8 decodes
during index lookups.
3) Add unsigned comparator to ByteBufferUtils and use it in
GenericIndexed.BYTE_BUFFER_STRATEGY. This is important because UTF-8
bytes can be compared as bytes if, and only if, the comparison
is unsigned.
4) Add specialization to GenericIndexed.singleThreaded().indexOf that
avoids needless ByteBuffer allocations.
5) Clarify that objects returned by ColumnIndexSupplier.as are not
thread-safe. DictionaryEncodedStringIndexSupplier now calls
singleThreaded() on all relevant GenericIndexed objects, saving
a ByteBuffer allocation per access.
Also:
1) Fix performance regression in LikeFilter: since #12315, it applied
the suffix matcher to all values in range even for type MATCH_ALL.
2) Add ObjectStrategy.canCompare() method. This fixes LikeFilterBenchmark,
which was broken due to calls to strategy.compare in
GenericIndexed.fromIterable.
* Add like-filter implementation tests.
* Add in-filter implementation tests.
* Add tests, fix issues.
* Fix style.
* Adjustments from review.
* SQL: Add is_active to sys.segments, update examples and docs.
is_active is short for:
(is_published = 1 AND is_overshadowed = 0) OR is_realtime = 1
It's important because this represents "all the segments that should
be queryable, whether or not they actually are right now". Most of the
time, this is the set of segments that people will want to look at.
The web console already adds this filter to a lot of its queries,
proving its usefulness.
This patch also reworks the caveat at the bottom of the sys.segments
section, so its information is mixed into the description of each result
field. This should make it more likely for people to see the information.
* Wording updates.
* Adjustments for spellcheck.
* Adjust IT.
- Add user friendly error messages for missing or incorrect OVERWRITE clause for REPLACE SQL query
- Move validation of missing OVERWRITE clause at code level instead of parser for custom error message
Relevant Issue: #11929
- Add custom replace statement to Druid SQL parser.
- Edit DruidPlanner to convert relevant fields to Query Context.
- Refactor common code with INSERT statements to reuse them for REPLACE where possible.
Following up on #12315, which pushed most of the logic of building ImmutableBitmap into BitmapIndex in order to hide the details of how column indexes are implemented from the Filter implementations, this PR totally refashions how Filter consume indexes. The end result, while a rather dramatic reshuffling of the existing code, should be extraordinarily flexible, eventually allowing us to model any type of index we can imagine, and providing the machinery to build the filters that use them, while also allowing for other column implementations to implement the built-in index types to provide adapters to make use indexing in the current set filters that Druid provides.

* Vectorized version of string last aggregator
* Updating string last and adding testcases
* Updating code and adding testcases for serializable pairs

* Reduce allocations due to Jackson serialization.
This patch attacks two sources of allocations during Jackson
serialization:
1) ObjectMapper.writeValue and JsonGenerator.writeObject create a new
DefaultSerializerProvider instance for each call. It has lots of
fields and creates pressure on the garbage collector. So, this patch
adds helper functions in JacksonUtils that enable reuse of
SerializerProvider objects and updates various call sites to make
use of this.
2) GroupByQueryToolChest copies the ObjectMapper for every query to
install a special module that supports backwards compatibility with
map-based rows. This isn't needed if resultAsArray is set and
all servers are running Druid 0.16.0 or later. This release was a
while ago. So, this patch disables backwards compatibility by default,
which eliminates the need to copy the heavyweight ObjectMapper. The
patch also introduces a configuration option that allows admins to
explicitly enable backwards compatibility.

The query context is a way that the user gives a hint to the Druid query engine, so that they enforce a certain behavior or at least let the query engine prefer a certain plan during query planning. Today, there are 3 types of query context params as below.
Default context params. They are set via druid.query.default.context in runtime properties. Any user context params can be default params.
User context params. They are set in the user query request. See https://druid.apache.org/docs/latest/querying/query-context.html for parameters.
System context params. They are set by the Druid query engine during query processing. These params override other context params.
Today, any context params are allowed to users. This can cause
1) a bad UX if the context param is not matured yet or
2) even query failure or system fault in the worst case if a sensitive param is abused, ex) maxSubqueryRows.
This PR adds an ability to limit context params per user role. That means, a query will fail if you have a context param set in the query that is not allowed to you. To do that, this PR adds a new built-in resource type, QUERY_CONTEXT. The resource to authorize has a name of the context param (such as maxSubqueryRows) and the type of QUERY_CONTEXT. To allow a certain context param for a user, the user should be granted WRITE permission on the context param resource. Here is an example of the permission.
{
"resourceAction" : {
"resource" : {
"name" : "maxSubqueryRows",
"type" : "QUERY_CONTEXT"
},
"action" : "WRITE"
},
"resourceNamePattern" : "maxSubqueryRows"
}
Each role can have multiple permissions for context params. Each permission should be set for different context params.
When a query is issued with a query context X, the query will fail if the user who issued the query does not have WRITE permission on the query context X. In this case,
HTTP endpoints will return 403 response code.
JDBC will throw ForbiddenException.
Note: there is a context param called brokerService that is used only by the router. This param is used to pin your query to run it in a specific broker. Because the authorization is done not in the router, but in the broker, if you have brokerService set in your query without a proper permission, your query will fail in the broker after routing is done. Technically, this is not right because the authorization is checked after the context param takes effect. However, this should not cause any user-facing issue and thus should be OK. The query will still fail if the user doesn’t have permission for brokerService.
The context param authorization can be enabled using druid.auth.authorizeQueryContextParams. This is disabled by default to avoid any hassle when someone upgrades his cluster blindly without reading release notes.
For a query like
INSERT INTO tablename SELECT channel, added as count FROM wikipedia the error message is Encountered "as count". However, for the insert statement
INSERT INTO t SELECT channel, added as count FROM wikipedia PARTITIONED BY ALL
returns INSERT statements must specify PARTITIONED BY clause explictly (incorrectly). This PR corrects this.
Add EOF to end of Druid SQL Insert statements
Rename SQL Insert statements in the parser to reflect the behaviour change
Added Calcites InQueryThreshold as a query context parameter. Setting this parameter appropriately reduces the time taken for queries with large number of values in their IN conditions.
* Fix error message for groupByEnableMultiValueUnnesting.
It referred to the incorrect context parameter.
Also, create a dedicated exception class, to allow easier detection of this
specific error.
* Fix other test.
* More better error messages.
* Test getDimensionName method.
* upgrade Airline to Airline 2
https://github.com/airlift/airline is no longer maintained, updating to
https://github.com/rvesse/airline (Airline 2) to use an actively
maintained version, while minimizing breaking changes.
Note, this is a backwards incompatible change, and extensions relying on
the CliCommandCreator extension point will also need to be updated.
* fix dependency checks where jakarta.inject is now resolved first instead
of javax.inject, due to Airline 2 using jakarta
As part of #12078 one of the followup's was to have a specific config which does not allow accidental unnesting of multi value columns if such columns become part of the grouping key.
Added a config groupByEnableMultiValueUnnesting which can be set in the query context.
The default value of groupByEnableMultiValueUnnesting is true, therefore it does not change the current engine behavior.
If groupByEnableMultiValueUnnesting is set to false, the query will fail if it encounters a multi-value column in the grouping key.

#12163 makes PARTITIONED BY a required clause in INSERT queries. While this is required, if a user accidentally omits the clause, it emits a JavaCC/Calcite error, since it's syntactically incorrect. The error message is cryptic. Since it's a custom clause, this PR aims to make the clause optional on the syntactic side, but move the validation to DruidSqlInsert where we can surface a friendlier error.

Fixes a bug because of which some SQL queries cannot be parsed using druid convention. Specifically, these queries translate to an inline datasource and have some null values. Calcite internally uses NULL as SQL type for these literals and that is not supported by the druid.
I am now allowing null column types to be returned while building RowSignature in org.apache.druid.sql.calcite.table.RowSignatures#fromRelDataType. RowSignature already allows null column type for any column. Doing so should also fix bindable queries such as select (1,2). When such queries are run with headers set to true, we get an exception in org.apache.druid.sql.http.ArrayWriter#writeHeader. This is again a similar exception to the one addressed in this PR. Because SQL type for the result column is RECORD and that doesn't have a corresponding columnType.

This PR changes the value of the property `druid.sql.planner.useGroupingSetForExactDistinct` from `false` to `true` in the runtime.properties files, so that newer installations have this property as `true`, while the default still remains as `false`.
The flag determines how queries which contain an aggregation over `DISTINCT` like `SELECT COUNT(DISTINCT foo.dim1) FILTER(WHERE foo.cnt = 1), SUM(foo.cnt) FROM druid.foo` get planned by Calcite. With the flag being set to false, it plans it via joins, whereas with it being set to true, the query is set using grouping sets.
There is a known issue with Calcite (https://github.com/apache/druid/issues/7953), where an NPE is thrown while planning the above query with joins. There is no such issue while planning the query using grouping sets.

Related to #11188
The above mentioned PR allowed timeseries queries to return a default result, when queries of type: select count(*) from table where dim1="_not_present_dim_" were executed. Before the PR, it returned no row, after the PR, it would return a row with value of count(*) as 0 (as expected by SQL standards of different dbs).
In Grouping#applyProject, we can sometimes perform optimization of a groupBy query to a timeseries query if possible (when the keys of the groupBy are constants, as generated by automated tools). For example, in select count(*) from table where dim1="_present_dim_" group by "dummy_key", the groupBy clause can be removed. However, in the case when the filter doesn't return anything, i.e. select count(*) from table where dim1="_not_present_dim_" group by "dummy_key", the behavior of general databases would be to return nothing, while druid (due to above change) returns an empty row. This PR aims to fix this divergence of behavior.
Example cases:
select count(*) from table where dim1="_not_present_dim_" group by "dummy_key".
CURRENT: Returns a row with count(*) = 0
EXPECTED: Return no row
select 'A', dim1 from foo where m1 = 123123 and dim1 = '_not_present_again_' group by dim1
CURRENT: Returns a row with ('A', 'wat')
EXPECTED: Return no row
To do this, a boolean droppedDimensionsWhileApplyingProject has been added to Grouping which is true whenever we make changes to the original shape with optimization. Hence if a timeseries query has a grouping with this set to true, we set skipEmptyBuckets=true in the query context (i.e. donot return any row).
DruidLogicalValuesRule while transforming to DruidRel can return incorrect values, if during the creation of the literal it was created from a float value. The BigDecimal representation stores 123.0, and it seems that using RexLiteral's method while conversion returns the inflated value (which is 1230). I am unsure if this is intentional from Calcite's perspective, and the actual change should be done somewhere else.
Extract the values of INT/LONG from the RexLiteral in the DruidLogicalValuesRule, via BigDecimal.longValue() method.
changes:
* IncrementalIndex is now a ColumnInspector
* fixes performance regression from using map of ColumnCapabilities from IncrementalIndex as a RowSignature
In this PR, we will now return 400 instead of 500 when SQL query cannot be planned. I also fixed a bug where error messages were not getting sent to the users in case the rules throw UnsupportSQLQueryException.
DruidSchema consists of a concurrent HashMap of DataSource -> Segement -> AvailableSegmentMetadata. AvailableSegmentMetadata contains RowSignature of the segment, and for each segment, a new object is getting created. RowSignature is an immutable class, and hence it can be interned, and this can lead to huge savings of memory being used in broker, since a lot of the segments of a table would potentially have same RowSignature.
This PR does two things
1. It adds the capability to surface missing features in SQL to users - The calcite planner will explore through multiple rules to convert a logical SQL query to a druid native query. Some rules change the shape of the query itself, optimize it and some rules are responsible for translating the query into a druid native query. These are DruidQueryRule, DruidOuterQueryRule, DruidJoinRule, DruidUnionDataSourceRule, DruidUnionRule etc. These rules will look at SQL and will do the necessary transformation. But if the rule can't transform the query, it returns back the control to the calcite planner without recording why was it not able to transform. E.g. there is a join query with a non-equal join condition. DruidJoinRule will look at the condition, see that it is not supported, and return back the control. The reason can be that a query can be planned in many different ways so if one rule can't parse it, the query may still be parseable by other rules. In this PR, we are intercepting these gaps and passing them back to the user if the query could not be planned at all.
2. The said capability has been used to generate actionable errors for some common unsupported SQL features. However, not all possible errors are covered and we can keep adding more in the future.
Druid currently has 2 serverViews, regular serverView and filtered serverView. The regular serverView is used to monitor all segment announcements from all data nodes (historicals, tasks, indexers). The filtered serverView is used when you want to watch segment announcements from particular tiers. Since these server views keep track of different sets of druidServers and segments in memory, they should be maintained separately. However, they currently share the same name for their executorService, which can cause confusion and make debugging harder especially in the broker since it is using both serverViews, the filtered view for normal query processing and the regular view to serve the servers table (I'm unsure whether this is intended or whether this is a good behavior). This PR changes it to a more obvious name.
This PR also removes SingleServerInventoryView. This view was deprecated a long time ago and has not been documented at least since 0.13 (#6127). I also don't think this can be better in any case than BatchServerInventoryView. Finally, I merged AbstractCuratorServerInventoryView and BatchServerInventoryView as we no longer need AbstractCuratorServerInventoryView after SingleServerInventoryView is removed.
* Enhancements to IndexTaskClient.
1) Ability to use handlers other than StringFullResponseHandler. This
functionality is not used in production code yet, but is useful
because it will allow tasks to communicate with each other in
non-string-based formats and in streaming fashion. In the future,
we'll be able to use this to make task-to-task communication
more efficient.
2) Truncate server errors at 1KB, so long errors do not pollute logs.
3) Change error log level for retryable errors from WARN to INFO. (The
final error is still WARN.)
4) Harmonize log and exception messages to have a more consistent format.
* Additional tests and improvements.
* allow `DruidSchema` to fallback to segment metadata type if typeSignature is null, to avoid producing incorrect SQL schema if broker is upgraded to 0.23 before historicals
* mmm, forbidden tests
changes:
* adds new config, druid.expressions.useStrictBooleans which make longs the official boolean type of all expressions
* vectorize logical operators and boolean functions, some only if useStrictBooleans is true

Currently, when we try to do EXPLAIN PLAN FOR, it returns the structure of the SQL parsed (via Calcite's internal planner util), which is verbose (since it tries to explain about the nodes in the SQL, instead of the Druid Query), and not representative of the native Druid query which will get executed on the broker side.
This PR aims to change the format when user tries to EXPLAIN PLAN FOR for queries which are executed by converting them into Druid's native queries (i.e. not sys schemas).
Add the ability to pass time column in first/last aggregator (and latest/earliest SQL functions). It is to support cases where the time to query upon is stored as a part of a column different than __time. Also, some other logical time column can be specified.
* SQL INSERT planner support.
The main changes are:
1) DruidPlanner is able to validate and authorize INSERT queries. They
require WRITE permission on the target datasource.
2) QueryMaker is now an interface, and there is a QueryMakerFactory that
creates instances of it. There is only one production implementation
of each (NativeQueryMaker and NativeQueryMakerFactory), which
together behave the same way as the former QueryMaker class. But this
opens the door to executing queries in ways other than the Druid
query stack, and is used by unit tests (CalciteInsertDmlTest) to
test the INSERT planning functionality.
3) Adds an EXTERN table macro that allows references external data using
InputSource and InputFormat from Druid's batch ingestion API. This is
not exposed in production yet, but is used by unit tests.
4) Adds a QueryFeature concept that enables the planner to change its
behavior slightly depending on the capabilities of the execution
system.
5) Adds an "AuthorizableOperator" concept that enables SqlOperators
to require additional permissions. This is used by the EXTERN table
macro.
Related odds and ends:
- Add equals, hashCode, toString methods to InlineInputSource. Aids in
the "from external" tests in CalciteInsertDmlTest.
- Add JSON-serializability to RowSignature.
- Move the SQL string inside PlannerContext so it is "baked into" the
planner when the planner is created. Cleans up the code a bit, since
in practice, the same query is passed in every time to the
same planner anyway.

DruidRexExecutor while reducing Arrays, specially numeric arrays, doesn't convert the value from ExprResult's type to BigDecimal, which causes makeLiteral to cast the values. Also, if NaN or Infinite values are present in the array, the error is a generic NumberFormatException. For example:
SELECT ARRAY[1.11, 2.22] returns [1, 2]
SELECT SQRT(-1) throws a generic NumberFormatException instead of IAE
This PR introduces change to cast the numeric values to BigDecimal since Calcite's library understands that easily, and doesn't perform casts.
* Scan: Add "orderBy" parameter.
This patch adds an API for requesting non-time orderings, although it
does not actually add the ability to execute such queries.
The changes are done in such a way that no matter how Scan query objects
are constructed, they will have a correct "getOrderBy". This will enable
us to switch the execution to exclusively use "getOrderBy" later on when
it's implemented.
Scan queries are serialized such that they only include "order" (time
order) if the ordering is time-based, and they only include "orderBy" if
the ordering is non-time-based. This maximizes compatibility with
the existing API while also providing a clean look for formatted queries.
Because this patch does not include execution logic, if someone actually
tries to run a query with non-time ordering, then they will get an error
like "Cannot execute query with orderBy [quality ASC]".

* Use a simple class to sanitize sanitizable errors and log them
The purpose of this is to sanitize JDBC errors, but can sanitize other errors
if they implement SanitizableError Interface
add a class to log errors and sanitize them
added a simple test that tests out that the error gets sanitized

For example, an admin can set:
druid.sql.approxCountDistinct.function = APPROX_COUNT_DISTINCT_DS_HLL

* SQL: Allow Scans to be used as outer queries.
This has been possible in the native query system for a while, but the capability
hasn't yet propagated into the SQL layer. One example of where this is useful is
a query like:
SELECT * FROM (... LIMIT X) WHERE <filter>
Because this expands the kinds of subquery structures the SQL layer will consider,
it was also necessary to improve the cost calculations. These changes appear in
PartialDruidQuery and DruidOuterQueryRel. The ideas are:
- Attach per-column penalties to the output signature of each query, instead of to
the initial projection that starts a query. This encourages moving projections
into subqueries instead of leaving them on outer queries.
- Only attach penalties to projections if there are actually expressions happening.
So, now, projections that simply reorder or remove fields are free.
- Attach a constant penalty to every outer query. This discourages creating them
when they are not needed.
The changes are generally beneficial to the test cases we have in CalciteQueryTest.
Most plans are unchanged, or are changed in purely cosmetic ways. Two have changed
for the better:
- testUsingSubqueryWithLimit now returns a constant from the subquery, instead of
returning every column.
- testJoinOuterGroupByAndSubqueryHasLimit returns a minimal set of columns from
the innermost subquery; two unnecessary columns are no longer there.
* Fix various DS operator conversions.
These were all implemented as direct conversions, which isn't appropriate
because they do not actually map onto native functions. These are only
usable as post-aggregations.

The SQL "array" and "object" formats are intended to return invalid JSON
(lacking a ] terminator) if an error occurs midstream. This enables callers
to detect truncated responses. But JsonGenerators, by default, close JSON
arrays even when not explicitly told to.
This patch disables automatic array closing, which fixes the problem with
truncated response detection. It also adds tests for truncated responses
for all result formats.

This PR fixes the incorrect results for query :
SELECT dim1, l1.k FROM foo LEFT JOIN (select k || '' as k from lookup.lookyloo group by 1) l1 ON foo.dim1 = l1.k WHERE l1.k IS NOT NULL (in CalciteQueryTests)
In the current code, the WHERE clause gets removed from the top of the left join and is pushed to the table foo
leading to incorrect results.
The fix for such a situation is done by :
Converting such left joins into inner joins (since logically the mentioned left join query is equivalent to an inner join) using Calcite while maintaining that the druid execution layer can execute such inner joins.
Preferring converted inner joins over original left joins in our cost model
This PR splits current SegmentLoader into SegmentLoader and SegmentCacheManager.
SegmentLoader - this class is responsible for building the segment object but does not expose any methods for downloading, cache space management, etc. Default implementation delegates the download operations to SegmentCacheManager and only contains the logic for building segments once downloaded. . This class will be used in SegmentManager to construct Segment objects.
SegmentCacheManager - this class manages the segment cache on the local disk. It fetches the segment files to the local disk, can clean up the cache, and in the future, support reserve and release on cache space. [See https://github.com/Make SegmentLoader extensible and customizable #11398]. This class will be used in ingestion tasks such as compaction, re-indexing where segment files need to be downloaded locally.

Users sometimes make typos when picking timezones - like `America/Los Angeles`
instead of `America/Los_Angeles` instead of defaulting to UTC, this change
makes it so that an error is thrown instead notifying the user of their mistake.
A constant expression may evaluate to Double.NEGATIVE_INFINITY/Double.POSITIVE_INFINITY/Double.NAN e.g. log10(0). When using such an expression in native queries, the user will get the corresponding value without any error. In SQL, however, the user will run into NumberFormatException because we convert the double to big-decimal while constructing a literal numeric expression. This probably should be fixed in calcite - see https://issues.apache.org/jira/browse/CALCITE-2067. This PR adds a verbose error message so that users can take corrective action without scratching their heads.

* Fix vectorized cardinality bug on certain string columns.
Fixes a bug introduced in #11182, related to the fact that in some cases,
ColumnProcessors.makeVectorProcessor will call "makeObjectProcessor"
instead of "makeSingleValueDimensionProcessor" or
"makeMultiValueDimensionProcessor". CardinalityVectorProcessorFactory
improperly ignored calls to "makeObjectProcessor".
In addition to fixing the bug, I added this detail to the javadocs for
VectorColumnProcessorFactory, to prevent others from running into the
same thing in the future. They do not currently call out this case.
* Improve test coverage.
* Additional fixes.
* ARRAY_AGG sql aggregator function
* add javadoc
* spelling
* review stuff, return null instead of empty when nil input
* review stuff
* Update sql.md
* use type inference for finalize, refactor some things
* Vectorize the cardinality aggregator.
Does not include a byRow implementation, so if byRow is true then
the aggregator still goes through the non-vectorized path.
Testing strategy:
- New tests that exercise both styles of "aggregate" for supported types.
- Some existing tests have also become active (note the deleted
"cannotVectorize" lines).
* Adjust whitespace.
* Enable rewriting certain inner joins as filters.
The main logic for doing the rewrite is in JoinableFactoryWrapper's
segmentMapFn method. The requirements are:
- It must be an inner equi-join.
- The right-hand columns referenced by the condition must not contain any
duplicate values. (If they did, the inner join would not be guaranteed
to return at most one row for each left-hand-side row.)
- No columns from the right-hand side can be used by anything other than
the join condition itself.
HashJoinSegmentStorageAdapter is also modified to pass through to
the base adapter (even allowing vectorization!) in the case where 100%
of join clauses could be rewritten as filters.
In support of this goal:
- Add Query getRequiredColumns() method to help us figure out whether
the right-hand side of a join datasource is being used or not.
- Add JoinConditionAnalysis getRequiredColumns() method to help us
figure out if the right-hand side of a join is being used by later
join clauses acting on the same base.
- Add Joinable getNonNullColumnValuesIfAllUnique method to enable
retrieving the set of values that will form the "in" filter.
- Add LookupExtractor canGetKeySet() and keySet() methods to support
LookupJoinable in its efforts to implement the new Joinable method.
- Add "enableRewriteJoinToFilter" feature flag to
JoinFilterRewriteConfig. The default is disabled.
