* Lazy-ify ValueMatcher BitSet optimization for string dimensions.
The idea is that if the prior evaluated filters are decently selective,
such that they mean we won't see all possible values of the later
filters, then the eager version of the optimization is too wasteful.
This involves checking an extra bitset, but the overhead is small even
if the lazy-ification is useless.
* Remove import.
* Minor transformation
* fixes#5814
changes:
* pass `StorageAdapter` to topn algorithms to get things like if column is 'sorted' or if query interval is smaller than segment granularity, instead of using `io.druid.segment.Capabilities`
* remove `io.druid.segment.Capabilities` since it had one purpose, supplying `dimensionValuesSorted` which is now provided directly by `StorageAdapter`.
* added test for topn optimization path checking
* add Capabilities back since StorageAdapter is marked PublicApi
* oops
* add javadoc, fix build i think
* correctly revert api changes
* fix intellij fail

* The check for maxBytesInMemory should be >= 0 instead of > 0
* if the default value is 0, the actual check could be skipped
* fix the message for persistReasons
* Address PR comments
* if maxBytes set -1, make is Long.MAX_VAL, so we do not need to check if it's 0 or -1
* set the maxBytesTuningconfig in AppenderatorImpl constructor to avoid duplicate code
* fix the failing test cases
* Address PR comments
* This commit introduces a new tuning config called 'maxBytesInMemory' for ingestion tasks
Currently a config called 'maxRowsInMemory' is present which affects how much memory gets
used for indexing.If this value is not optimal for your JVM heap size, it could lead
to OutOfMemoryError sometimes. A lower value will lead to frequent persists which might
be bad for query performance and a higher value will limit number of persists but require
more jvm heap space and could lead to OOM.
'maxBytesInMemory' is an attempt to solve this problem. It limits the total number of bytes
kept in memory before persisting.
* The default value is 1/3(Runtime.maxMemory())
* To maintain the current behaviour set 'maxBytesInMemory' to -1
* If both 'maxRowsInMemory' and 'maxBytesInMemory' are present, both of them
will be respected i.e. the first one to go above threshold will trigger persist

* Proper syntax from https://github.com/policeman-tools/forbidden-apis/wiki/SignaturesSyntax
* Fix round robining in router.
Say that ten times fast.
For query endpoints, AsyncQueryForwardingServlet called hostFinder.getDefaultServer()
to set a default server, followed by hostFinder.getServer(inputQuery) to override it
with query-specific routing. Since hostFinder is round-robin, this skips a server.
When there are only two servers, one server is _always_ skipped and the router sends
all queries to the same broker.
* Adjust spacing.
* SegmentMetadataQuery: Fix default interval handling.
PR #4131 introduced a new copy builder for segmentMetadata that did
not retain the value of usingDefaultInterval. This led to it being
dropped and the default-interval handling not working as expected.
Instead of using the default 1 week history when intervals are not
provided, the segmentMetadata query would query _all_ segments,
incurring an unexpected performance hit.
This patch fixes the bug and adds a test for the copy builder.
* Intervals
* Support for disabling bitmap indexes.
Can save space for columns where bitmap indexes are pointless (like
free-form text).
* Remove import.
* Fix CompactionTaskTest.
* Update for review comments.
* Review comments, tests.
* Fix test.
* Fix two improper casts in HavingSpecMetricComparator.
Fixes two things:
1. An improper double-to-long cast when comparing double metrics to any
kind of value, which was a regression from #4883.
2. An improper double-to-long cast when comparing a long/int metric to a
double/float value: the value was cast to long/int, drawing strange
conclusions like int 100 matching a havingSpec of equalTo(100.5).
* Add comments.
* Remove extraneous comment.
* Simplify code a bit.
* Properly set "identity" in query metrics.
This patch adds an "identity" field to QueryPlus and sets it in
QueryLifecycle when the query starts executing. This is important
because it allows it to be used for future QueryMetrics created
by that QueryPlus object.
We also add "identity" to the request-level QueryMetrics object
created in emitLogsAndMetrics.
* Remove unused method.
* Fix races in LookupSnapshotTaker, CoordinatorPollingBasicAuthenticatorCacheManager.
Both were susceptible to the following conditions:
1. Two JVMs on the same machine (perhaps two peons) could conflict by one reading while the
other was writing, or by writing to the file at the same time.
2. One JVM could partially write a file, then crash, leaving a truncated file.
* Use StringUtils.format
* Use both Joad Ids and Java IDs as Timezone to string readers
Change-Id: Ieb5c18559879f3f3a0104912ce2f0a354ad0aac3

The behavior is configurable through druid.extensions.useExtensionClassloaderFirst.
It is useful when extensions want to load a dependency different from one provided
by Druid, for example a different version of geoip or protobuf.
