Broker: Add ability to inline subqueries. (#9533)
* Broker: Add ability to inline subqueries.

The main changes:

- ClientQuerySegmentWalker: Add ability to inline queries.
- Query: Add "getSubQueryId" and "withSubQueryId" methods.
- QueryMetrics: Add "subQueryId" dimension.
- ServerConfig: Add new "maxSubqueryRows" parameter, which is used by
  ClientQuerySegmentWalker to limit how many rows can be inlined per
  query.
- IndexedTableJoinMatcher: Allow creating keys on top of unknown types,
  by assuming they are strings. This is useful because not all types are
  known for fields in query results.
- InlineDataSource: Store RowSignature rather than component parts. Add
  more zealous "equals" and "hashCode" methods to ease testing.
- Moved QuerySegmentWalker test code from CalciteTests and
  SpecificSegmentsQueryWalker in druid-sql to QueryStackTests in
  druid-server. Use this to spin up a new ClientQuerySegmentWalkerTest.

* Adjustments from CI.

* Fix integration test.

Move RowSignature from druid-sql to druid-processing and make use of it. (#9508)
* Move RowSignature from druid-sql to druid-processing and make use of it.

1) Moved (most of) RowSignature from sql to processing. Left behind the SQL-specific
   stuff in a RowSignatures utility class. It also picked up some new convenience
   methods along the way.
2) There were a lot of places in the code where Map<String, ValueType> was used to
   associate columns with type info. These are now all replaced with RowSignature.
3) QueryToolChest's resultArrayFields method is replaced with resultArraySignature,
   and it now provides type info.

* Fix up extensions.

* Various fixes

Link up row-based datasources to serving layer. (#9503)
* Link up row-based datasources to serving layer.

- Add SegmentWrangler interface that allows linking of DataSources to Segments.
- Add LocalQuerySegmentWalker that uses SegmentWranglers to compute queries on
  data that is available locally.
- Modify ClientQuerySegmentWalker to use LocalQuerySegmentWalker when the base
  datasource is concrete and not a table.
- Add SegmentWranglerModule to the Broker so it has them available and can
  properly instantiate . LocalQuerySegmentWalkers.
- Set InlineDataSource and LookupDataSource to concrete, since they can be
  directly queried now.

* Fix tests.

Harmonization and bug-fixing for selector and filter behavior on unknown types. (#9484)
* Harmonization and bug-fixing for selector and filter behavior on unknown types.

- Migrate ValueMatcherColumnSelectorStrategy to newer ColumnProcessorFactory
  system, and set defaultType COMPLEX so unknown types can be dynamically matched.
- Remove ValueGetters in favor of ColumnComparisonFilter doing its own thing.
- Switch various methods to use convertObjectToX when casting to numbers, rather
  than ad-hoc and inconsistent logic.
- Fix bug in RowBasedExpressionColumnValueSelector: isBindingArray should return
  true even for 0- or 1- element arrays.
- Adjust various javadocs.

* Add throwParseExceptions option to Rows.objectToNumber, switch back to that.

* Update tests.

* Adjust moment sketch tests.

Add config option for namespacePrefix (#9372)
* Add config option for namespacePrefix

opentsdb emitter sends metric names to opentsdb verbatim as what druid
names them, for example "query.count", this doesn't fit well with a
central opentsdb server which might have namespaced metrics, for example
"druid.query.count". This adds support for adding an optional prefix.

The prefix also gets a trailing dot (.), after it, so the metric name
becomes <namespacePrefix>.<metricname>

configureable as "druid.emitter.opentsdb.namespacePrefix", as
documented.

* Spelling for PR #9372

Added "namespacePrefix" to .spelling exceptions, it's a variable name
used in documentation for opentsdb-emitter.

* fixing tests for PR #9372

changed naming of variables to be more descriptive
added test of prefix being an empty string: "".
added a conditional to buildNamespacePrefix to check for empty string
being fed if EventConverter called without OpentsdbEmitterConfig
instance.

* fixing checkstyle errors for PR #9372

used == to compare literal string, should be equals()

* cleaned up and updated PR #9372

Created a buildMetric function as suggested by clintropolis, and
removed redundant tests for empty strings as they're only used when
calling EventConverter directly without going through
OpentsdbEmitterConfig.

* consistent naming of tests PR #9372

Changed names of tests in files to match better with what it was
actually testing

changed check for Strings.isNullOrEmpty to just check for `null`, as
empty string valued `namespacePrefix` is handled in
OpentsdbEmitterConfig.

Use DataSourceAnalysis throughout the query stack. (#9239)
Builds on #9235, using the datasource analysis functionality to replace various ad-hoc
approaches. The most interesting changes are in ClientQuerySegmentWalker (brokers),
ServerManager (historicals), and SinkQuerySegmentWalker (indexing tasks).

Other changes related to improving how we analyze queries:

1) Changes TimelineServerView to return an Optional timeline, which I thought made
   the analysis changes cleaner to implement.
2) Added QueryToolChest#canPerformSubquery, which is now used by query entry points to
   determine whether it is safe to pass a subquery dataSource to the query toolchest.
   Fixes an issue introduced in #5471 where subqueries under non-groupBy-typed queries
   were silently ignored, since neither the query entry point nor the toolchest did
   anything special with them.
3) Removes the QueryPlus.withQuerySegmentSpec method, which was mostly being used in
   error-prone ways (ignoring any potential subqueries, and not verifying that the
   underlying data source is actually a table). Replaces with a new function,
   Queries.withSpecificSegments, that includes sanity checks.

* Address security vulnerabilities CVSS >= 7

Update dependencies to address security vulnerabilities with CVSS scores
of 7 or higher. A new Travis CI job is added to prevent new
high/critical security vulnerabilities from being added.

Updated dependencies:
- api-util 1.0.0 -> 1.0.3
- jackson 2.9.10 -> 2.10.1
- kafka 2.1.0 -> 2.1.1
- libthrift 0.10.0 -> 0.13.0
- protobuf 3.2.0 -> 3.11.0

The following high/critical security vulnerabilities are currently
suppressed (so that the new Travis CI job can be added now) and are left
as future work to fix:
- hibernate-validator:5.2.5
- jackson-mapper-asl:1.9.13
- libthrift:0.6.1
- netty:3.10.6
- nimbus-jose-jwt:4.41.1

Gian Merlino c44452f0c1 Tidy up lifecycle, query, and ingestion logging. (#8889)
* Tidy up lifecycle, query, and ingestion logging.

The goal of this patch is to improve the clarity and usefulness of
Druid's logging for cluster operators. For more information, see
https://twitter.com/cowtowncoder/status/1195469299814555648.

Concretely, this patch does the following:

- Changes a lot of INFO logs to DEBUG, and DEBUG to TRACE, with the
  goal of reducing redundancy and improving clarity by avoiding
  showing rarely-useful log messages. This includes most "starting"
  and "stopping" messages, and most messages related to individual
  columns.
- Adds new log4j2 templates that show operators how to enabled DEBUG
  logging for certain important packages.
- Eliminate stack traces for query errors, unless log level is DEBUG
  or more. This is useful because query errors often indicate user
  error rather than system error, but dumping stack trace often gave
  operators the impression that there was a system failure.
- Adds task id to Appenderator, AppenderatorDriver thread names. In
  the default log4j2 configuration, this will put them in log lines
  as well. It's very useful if a user is using the Indexer, where
  multiple tasks run in the same JVM.
- More consistent terminology when it comes to "sequences" (sets of
  segments that are handed-off together by Kafka ingestion) and
  "offsets" (cursors in partitions). These terms had been confused in
  some log messages due to the fact that Kinesis calls offsets
  "sequence numbers".
- Replaces some ugly toString calls with either the JSONification or
  something more operator-accessible (like a URL or segment identifier,
  instead of JSON object representing the same).

* Adjustments.

* Adjust integration test.

* oops

* fix race, add docs

* spelling, remove todo, add unhandled exception log

* cleanup, revert unintended change

* another unintended change

* review stuff

* add ParallelMergeCombiningSequenceBenchmark, fixes

* hyper-threading is the enemy

* fix initial start delay, lol

* more benchmark comments

* stable sequence generation time

* update defaults to use 100ms target time, 4096 batch size, 16384 initial yield, also update user docs

* add jmh thread based benchmarks, cleanup some stuff

* oops

* style

* add spread to jmh thread benchmark start range, more comments to benchmarks parameters and purpose

* retool benchmark to allow modeling more typical heterogenous heavy workloads

* spelling

* fix

* refactor benchmarks

* formatting

* docs

Roman Leventov 5c0fc0a13a Fix ambiguity about IndexerSQLMetadataStorageCoordinator.getUsedSegmentsForInterval() returning only non-overshadowed or all used segments (#8564)
* IndexerSQLMetadataStorageCoordinator.getTimelineForIntervalsWithHandle() don't fetch abutting intervals; simplify getUsedSegmentsForIntervals()

* Add VersionedIntervalTimeline.findNonOvershadowedObjectsInInterval() method; Propagate the decision about whether only visible segmetns or visible and overshadowed segments should be returned from IndexerMetadataStorageCoordinator's methods to the user logic; Rename SegmentListUsedAction to RetrieveUsedSegmentsAction, SegmetnListUnusedAction to RetrieveUnusedSegmentsAction, and UsedSegmentLister to UsedSegmentsRetriever

* Fix tests

* More fixes

* Add javadoc notes about returning Collection instead of Set. Add JacksonUtils.readValue() to reduce boilerplate code

* Fix KinesisIndexTaskTest, factor out common parts from KinesisIndexTaskTest and KafkaIndexTaskTest into SeekableStreamIndexTaskTestBase

* More test fixes

* More test fixes

* Add a comment to VersionedIntervalTimelineTestBase

* Fix tests

* Set DataSegment.size(0) in more tests

* Specify DataSegment.size(0) in more places in tests

* Fix more tests

* Fix DruidSchemaTest

* Set DataSegment's size in more tests and benchmarks
