groupBy: GroupByRowProcessor fixes, invert subquery context overrides. ( #3502 )
...
- Fix GroupByRowProcessor config overrides
- Fix GroupByRowProcessor resource limit checking
- Invert subquery context overrides such that for the subquery, its own
keys override keys from the outer query, not the other way around.
The last bit is necessary for the test to work, and seems like a better
way to do it anyway.

The old TopNFunction code did Sequences.toList on the input sequence before
using a priority queue to find the top N items. Now, the priority queue
is used in an accumulator, so there is no need to fully materialize the results.
Also removed equals/hashCode from the limitFn and remove limitFn from the
GroupByQuery's hashCode, since that wasn't necessary and the implementation
of hashCode wasn't correct anyway.

Follow-up to #1773 , which meant to add more useful query errors but
did not actually do so. Since that patch, any error other than
interrupt/cancel/timeout was reported as `{"error":"Unknown exception"}`.
With this patch, the error fields are:
- error, one of the specific strings "Query interrupted", "Query timeout",
"Query cancelled", or "Unknown exception" (same behavior as before).
- errorMessage, the message of the topmost non-QueryInterruptedException
in the causality chain.
- errorClass, the class of the topmost non-QueryInterruptedException
in the causality chain.
- host, the host that failed the query.

Fix FilteredAggregators at ingestion time and in groupBy v2 nested queries. ( #3312 )
...
The common theme between the two is they both create "fake" DimensionSelectors
that work on top of Rows. They both do it because there isn't really any
dictionary for the underlying Rows, they're just a stream of data. The fix for
both is to allow a DimensionSelector to tell callers that it has no dictionary
by returning CARDINALITY_UNKNOWN from getValueCardinality. The callers, in
turn, can avoid using it in ways that assume it has a dictionary.
Fixes #3311 .

Fix ClassCastException in nested v2 groupBys with timeouts. ( #3310 )

Add tests for the CCE and for a bunch of other groupBy stuff.
Also avoids setting the interrupted flag when InterruptedExceptions
happen, since this might interfere with resource closing, no other
query does it, and is probably pointless anyway since the thread
is likely to be a jetty thread that we don't actually want to set
an interrupt flag on.
Also fixes toString on OrderByColumnSpec.

resources are exhausted, by grouping those all up into a single merged
exception.

Share query handling between Appenderator and RealtimePlumber. ( #3248 )
...
Fixes inconsistent metric handling between the two implementations. Formerly,
RealtimePlumber only emitted query/segmentAndCache/time and query/wait and
Appenderator only emitted query/partial/time and query/wait (all per sink).
Now they both do the same thing:
- query/segmentAndCache/time, query/segment/time are the time spent per sink.
- query/cpu/time is the CPU time spent per query.
- query/wait/time is the executor waiting time per sink.
These generally match historical metrics, except segmentAndCache & segment
mean the same thing here, because one Sink may be partially cached and
partially uncached and we aren't splitting that out.

Alternative groupBy strategy. ( #2998 )
...
This patch introduces a GroupByStrategy concept and two strategies: "v1"
is the current groupBy strategy and "v2" is a new one. It also introduces
a merge buffers concept in DruidProcessingModule, to try to better
manage memory used for merging.
Both of these are described in more detail in #2987 .
There are two goals of this patch:
1. Make it possible for historical/realtime nodes to return larger groupBy
result sets, faster, with better memory management.
2. Make it possible for brokers to merge streams when there are no order-by
columns, avoiding materialization.
This patch does not do anything to help with memory management on the broker
when there are order-by columns or when there are nested queries. That could
potentially be done in a future patch.

More consistent empty-set filtering behavior on multi-value columns.

The behavior is now that filters on "null" will match rows with no
values. The behavior in the past was inconsistent; sometimes these
filters would match and sometimes they wouldn't.
Adds tests for this behavior to SelectorFilterTest and
BoundFilterTest, for query-level filters and filtered aggregates.

BoundFilter optimizations, and related interface changes.
...
BoundFilter:
- For lexicographic bounds, use bitmapIndex.getIndex to find the start and end points,
then union all bitmaps between those points.
- For alphanumeric bounds, iterate through dimValues, and union all bitmaps for values
matching the predicate.
- Change behavior for nulls: it used to be that the BoundFilter would never match nulls,
now it matches nulls if "" is allowed by the lower limit and not excluded by the
upper limit.
Interface changes:
- BitmapIndex: add `int getIndex(value)` to make it possible to get the index for a
value without retrieving the bitmap.
- BitmapIndex: remove `ImmutableBitmap getBitmap(value)`, change callers to `getBitmap(getIndex(value))`.
- BitmapIndexSelector: allow retrieving the underlying BitmapIndex through getBitmapIndex.
- Clarified contract of indexOf in Indexed, GenericIndexed.
Also added tests for SelectorFilter, NotFilter, and BoundFilter.

Filters: Add filter.toFilter method, use that instead of the instanceof chain in Filters.
...
I believe that the instanceof chain in Filters exists because in the past, Filter
and DimFilter were in different packages (DimFilter was in druid-client and Filter
was in druid-processing). And since druid-client didn't depend on druid-processing,
DimFilter couldn't have a toFilter method. But now it can.

All Filters should work with FilteredAggregators.
...
This removes Filter.makeMatcher(ColumnSelectorFactory) and adds a
ValueMatcherFactory implementation to FilteredAggregatorFactory so it can
take advantage of existing makeMatcher(ValueMatcherFactory) implementations.
This patch also removes the Bound-based method from ValueMatcherFactory. Its
only user was the SpatialFilter, which could use the Predicate-based method.

update querySegmentSpec when passing query to getQueryRunner
...
After finding the FireChief for a specific partition, Druid will need to find the specific queryRunner for each segment being queried by passing the query to FireChief. Currently Druid is passing the original query that contains all the segments need to be queried, it's possible that fireChief.getQueryRunner(query) returns more than 1 queryRunner because query.getIntervals() is not specific to a single segment.
In this patch, for each segment being queried, Druid will update the query with its corresponding SpecificSegmentSpec.

- Add "reportParseExceptions" option to realtime tuning configs. By default this is "false".
Behavior of the counters should now be:
- processed: Number of rows indexed, including rows where some fields could be parsed and some could not.
- thrownAway: Number of rows thrown away due to rejection policy.
- unparseable: Number of rows thrown away due to being completely unparseable (no fields salvageable at all).
If "reportParseExceptions" is true then "unparseable" will always be zero (because a parse error would
cause an exception to be thrown). In addition, "processed" will only include fully parseable rows
(because even partial parse failures will cause exceptions to be thrown).
Fixes #2510 .

Add comparator to HyperUniquesFinalizingPostAggregator.
...
This makes it possible to do groupBys with clauses like "HAVING uniques > 10".
Beforehand you couldn't do it with either an aggregator (because it returns
an HLLV1 which the havingSpec can't understand) or a finalized postaggregator
(because it didn't have a comparator).
Now you can at least do it with a finalizing postaggregator. Trying it with
the aggregator alone still doesn't work.
Added some topN and groupBy tests verifying the comparator, and added an
@Ignore test that should pass if havingSpecs are made work on the aggregator
directly.

SegmentMetadataQuery stuff:
- Simplify implementation of SegmentAnalyzer.
- Fix type names for realtime complex columns; this used to try to merge a nice type
name (like "hyperUnique") from mmapped segments with the word "COMPLEX" from incremental
index segments, leading to a merge failure. Now it always uses the nice name.
- Add hasMultipleValues to ColumnAnalysis.
- Add tests for both mmapped and incremental index segments.
- Update docs to include errorMessage.

SegmentMetadataQuery merging fixes.
...
- Fix merging when the INTERVALS analysisType is disabled, and add a test.
- Remove transformFn from CombiningSequence, use MappingSequence instead. transformFn did
not work for "accumulate" anyway, which made the tests wrong (the intervals should have
been condensed, but were not).
- Add analysisTypes to the Druids segmentMetadataQuery builder to make testing simpler.

New extension loading mechanism
...
1) Remove maven client from downloading extensions at runtime.
2) Provide a way to load Druid extensions and hadoop dependencies through file system.
3) Refactor pull-deps so that it can download extensions into extension directories.
4) Add documents on how to use this new extension loading mechanism.
5) Change the way how Druid tarball is generated. Now all the extensions + hadoop-client 2.3.0
are packaged within the Druid tarball.

Fix failure in nested groupBy with multiple aggregators with same fieldName
...
Version 2 - Throws an exception if an outer query references an
aggregator that doesn't exist in the inner query, and then uses the
inner query aggregator names to form the columns for the intermediate
incremental index.
Also deleted all the getRequiredColumns() methods which are no longer
being used.
We do something wacky by adding an aggregator factory for the post
aggregators when building the intermediate incremental index, otherwise
queries on post aggregate results fail because the data isn't in the
incremental index.
