* Optimize large InDimFilters
For large InDimFilters, in default mode, the filter does a linear check of the
set to see if it contains either an empty or null. If it does, the empties are
converted to nulls by passing through the entire list again.
Instead of this, in default mode, we attempt to remove an empty string from the
values that are passed to the InDimFilter. If an empty string was removed, we
add null to the set
* code review
* Revert "code review"
This reverts commit 61fe33ebf7.
* code review - less brittle
* support redis cluster
* add 'password', 'database' properties
* test cases passed
* update doc
* some improvements
* fix CI
* add more test cases to improve branch coverage
* fix dependency check for test
* resolve review comments
* Add SQL "OFFSET" clause.
Under the hood, this uses the new offset features from #10233 (Scan)
and #10235 (GroupBy). Since Timeseries and TopN queries do not currently
have an offset feature, SQL planning will switch from one of those to
Scan or GroupBy if users add an OFFSET.
Includes a refactoring to harmonize offset and limit planning using an
OffsetLimit wrapper class. This is useful because it ensures that the
various places that need to deal with offset and limit collapsing all
behave the same way, using its "andThen" method.
* Fix test and add another test.
* Segment backed broadcast join IndexedTable
* fix comments
* fix tests
* sharing is caring
* fix test
* i hope this doesnt fix it
* filter by schema to maybe fix test
* changes
* close join stuffs so it does not leak, allow table to directly make selector factory
* oops
* update comment
* review stuffs
* better check
* Add note about aggreations on floats
Floating point math is known to be unstable. Due to the way aggregators work
across segments it's possible for the same query operating on the same data to
produce slightly different results.
The same problem exists with any aggregators that are not commutative since
the merge order across segments is not guaranteed.
* Also talk about doubles
* Apply suggestions from code review
* remove DruidLeaderClient.goAsync(..) that does not follow redirect.
Replace its usage by DruidLeaadereClient.go(..) with
InputStreamFullResponseHandler
* remove ByteArrayResponseHolder dependency from JsonParserIterator
* add UT to cover lines in InputStreamFullResponseHandler
* refactor SystemSchema to reduce branches
* further reduce branches
* Revert "add UT to cover lines in InputStreamFullResponseHandler"
This reverts commit 330aba3dd9.
* UTs for InputStreamFullResponseHandler
* remove unused imports
* Add "offset" parameter to the Scan query.
It works by doing the query as normal and then throwing away the first
"offset" number of rows on the broker.
* Fix constructor call.
* Fix up JSONs.
* Fix call to ScanQuery.
* Doc update.
* Fix javadocs.
* Spotbugs, LGTM suppressions.
* Javadocs.
* Fix suppression.
* Stabilize Scan query result order, add tests.
* Update LGTM comment.
* Fixup.
* Test different batch sizes too.
* Nicer tests.
* Fix comment.
1) lookupId could return IDs beyond maxId if called with a recently added value.
2) getRow could return an ID for null beyond maxId, if null was recently
encountered in a dimension that initially didn't appear at all. (In this case,
the dictionary ID for null can be > 0).
Also add a comment explaining how this stuff is supposed to work.
* Fix broken sampler for re-indexer
When re-indexing a Druid datasource, the web-console would generate an
invalid inputFormat since the type is not specified.
* code review
* fix bug with realtime expressions on sparse string columns
* fix test

* Bug fix.
* checkstyle formatting fixes.
* CalciteQueryTest cases update.
* Separate test classes for FloatMaxAggregation and FloatMniAggregation.
* remove the cannotVectorize for float max/min aggregator in test.
* Tests in GroupByQueryRunner, GroupByTimeseriesQueryRunner and TimeseriesQueryRunner.
* Combine InDimFilter, InFilter.
There are two motivations:
1. Ensure that when HashJoinSegmentStorageAdapter compares its Filter
to the original one, and it is an "in" type, the comparison is by
reference and does not need to check deep equality. This is useful
when the "in" filter is very large.
2. Simplify things. (There isn't a great reason for the DimFilter and
Filter logic to be separate, and combining them reduces some
duplication.)

* Change color of Run button for native queries
When a user tries to run a native query, change the color of the button to
Druid's secondary color to indicate that the user is not running a SQL query.
Before this change, the web-console would indicate this by changing the text
of the button from Run (SQL queries) to Rune (native queries). Rune could be
confusing to users as this appears to be a typo.
