* Move scan-query from a contrib extension into core.
Based on a proposal at: https://groups.google.com/d/topic/druid-development/ME_OatUDnbk/discussion
This patch also adds support for virtual columns to the Scan query,
and updates Druid SQL to use Scan instead of Select.
This patch also makes some behavioral changes to handling of the __time
column. In particular, it is now is returned as "__time" rather than
"timestamp"; it is no longer included if you do not specifically ask for
it in your "columns"; and it is returned as a long rather than a string.
Users can revert time handling to the legacy extension behavior by
setting "legacy" : true in their queries, or setting the property
druid.query.scan.legacy = true. This is meant to provide a migration
path for users that were formerly using the contrib extension.
* Adjustments from review.
* Add back Select query.
* Adjust SQL docs.
* Restore SelectQuery link.
* SQL: Full TRIM support.
- Support trimming arbitrary characters
- Support BOTH, LEADING, and TRAILING
* Remove unused import.
* Fix tests, add RTRIM / LTRIM.
* Remove unused imports.
* BTRIM and docs.
* Replace for with foreach.
* Use internal-discovery and http for talking to overlord/coordinator leaders
* CuratorDruidNodeDiscovery.getAllNodes() best effort 30 sec wait for cache initialization
* DruidLeaderClientProvider to eagerly instantiate DruidNodeDiscovery when needed so that DruidNodeDiscovery impl cache gets initialized well in time
* Revert "DruidLeaderClientProvider to eagerly instantiate DruidNodeDiscovery when needed so that DruidNodeDiscovery impl cache gets initialized well in time"
This reverts commit f1a2432614ba56ddc2d55fe47e990d17fcfd6129.
* add lifecycle to DruidLeaderClient to early initialize DruidNodeDiscovery so that it has its cache update well in time
Expose version property for so that it may serialize/deserialize correctly
Expose version property for `CustomVersioningPolicy` so that it may serialize/deserialize correctly
Expose version property for CustomVersioningPolicy so that it may serialize/deserialize correctly
Expose version property for `CustomVersioningPolicy` so that it may serialize/deserialize correctly
* DruidLeaderSelector interface for leader election and Curator based impl. DruidCoordinator/TaskMaster are updated to use the new interface.
* add fake DruidNode binding in integration-tests module
* add docs on DruidLeaderSelector interface
* remove start/stop and keep register/unregister Listener in DruidLeaderSelector interface
* updated comments on DruidLeaderSelector
* cache the listener executor in CuratorDruidLeaderSelector
* use same latch owner name that was used before
* remove stuff related to druid.zk.paths.indexer.leaderLatchPath config
* randomize the delay when giving up leadership and restarting leader latch
* Factor QueryableIndexColumnSelectorFactory and IncrementalIndexColumnSelectorFactory out of QueryableIndexStorageAdapter and IncrementalIndexStorageAdapter; Add Offset.getBaseReadableOffset(); Remove OffsetHolder interface; Replace Cursor extends ColumnSelectorFactory with composition; Reduce indirection in ColumnValueSelectors created by QueryableIndexColumnSelectorFactory
* Don't override clone() in FilteredOffset (the prev. implementation was broken); Some warnings fixed
* Simplify Cursors in QueryableIndexStorageAdapter
* Address comments
* Remove unused and unimplemented methods from GenericColumn interface
