Broker backpressure. (#6313)
* Broker backpressure.

Adds a new property "druid.broker.http.maxQueuedBytes" and a new context
parameter "maxQueuedBytes". Both represent a maximum number of bytes queued
per query before exerting backpressure on the channel to the data server.

Fixes #4933.

* Fix query context doc.

Cache: Add maxEntrySize config, make groupBy cacheable by default. (#5108)
* Cache: Add maxEntrySize config.

The idea is this makes it more feasible to cache query types that
can potentially generate large result sets, like groupBy and select,
without fear of writing too much to the cache per query.

Includes a refactor of cache population code in CachingQueryRunner and
CachingClusteredClient, such that they now use the same CachePopulator
interface with two implementations: one for foreground and one for
background.

The main reason for splitting the foreground / background impls is
that the foreground impl can have a more effective implementation of
maxEntrySize. It can stop retaining subvalues for the cache early.

* Add CachePopulatorStats.

* Fix whitespace.

* Fix docs.

* Fix various tests.

* Add tests.

* Fix tests.

* Better tests

* Remove conflict markers.

* Fix licenses.

Fix spelling of "propagate" in various places. (#5896)
One of these is a configuration parameter (introduced in #5429),
but it's never been in a release, so I think it's ok to rename it.

Michael Schnupp 33b4eb624d fix freeSpacePercent in segmentCache.locations (#5765)
* fix freeSpacePercent in segmentCache.locations

* the check should probably test the other way around
* documentation should put the option in the right place
* examples have a superfluous backslash

* add test to verify correct behavior

* switch to Path and test with jimfs

Path allows to use different filesystems.
Jimfs provides an actual (in memory) filesystem.
This also allows more complex test scenarios.

The behavior should be unchanged by this commit.

* Revert "switch to Path and test with jimfs"

This reverts commit 8b9a418d65.

Jakub Kukul e2431ae161 Update defaultHadoopCoordinates in documentation. (#5720)
* Update defaultHadoopCoordinates in documentation.

To match changes applied in #5382.

* Remove a parameter with defaults from example configuration file.

If it has reasonable defaults, then why would it be in an example config file?

Also, it is yet another place that has been forgotten to be updated and will be forgotten in the future.

Also, if someone is running different hadoop version, then there's much more work to be done than just changing this property, so why give users false hopes?

* Fix typo in documentation.

Gian Merlino d51f5e058d SQL: Ditch CalciteConnection layer and add DruidMeta, extension aggregators. (#3852)
* SQL: Ditch CalciteConnection layer and add DruidMeta, extension aggregators.

Switched from CalciteConnection to Planner, bringing benefits:

- CalciteConnection's JDBC interface no longer sits between the SQL server
  (HTTP/Avatica) and Druid's query layer. Instead, the SQL servers can use
  Druid Sequence objects directly, reducing overhead in the query return path.

- Implemented our own Planner-based Avatica Meta, letting us control
  connection timeouts and connection / statement limits. The previous
  CalciteConnection-based implementation didn't have any limits or timeouts.

- The Planner interface lets us override the operator table, opening up
  SQL language extensions. This patch includes two: APPROX_COUNT_DISTINCT
  in core, and a QUANTILE aggregator in the druid-histogram extension.

Also:

- Added INFORMATION_SCHEMA metadata schema.

- Added tests for Unicode literals and escapes.

* Verify statement is actually open before closing it.

* More detailed INFORMATION_SCHEMA docs.

Gian Merlino e86859b228 SQL support for nested groupBys. (#3806)
* SQL support for nested groupBys.

Allows, for example, doing exact count distinct by writing:

  SELECT COUNT(*) FROM (SELECT DISTINCT col FROM druid.foo)

Contrast with approximate count distinct, which is:

  SELECT COUNT(DISTINCT col) FROM druid.foo

* Add deeply-nested groupBy docs, tests, and maxQueryCount config.

* Extract magic constants into statics.

* Rework rules to put preconditions in the "matches" method.
