* Adds kafka, URI, and JDBC namespace defintions
* Add ability to explicitly rename using a "namespace" which is a particular data collection that is loaded on all realtime, historic nodes, and brokers. If any of these nodes has the namespace extension, ALL nodes have the namespace extension.
* Add namespace caching and populating (can be on heap or off heap)
* Add NamespaceExtractionCacheManager for handling caches
* Added ExtractionNamespace for handling metadata on the extraction namespaces
* Added ExtractionNamespaceUpdate for handling metadata related to updates
* Add extension which caches renames from a kafka stream (requires kafka8)
* Added README.md for the namespace kafka extension
* Added docs
* Added namespace/size, namespace/count, namespace/deltaTasksStarted metrics
Add static config for namespaces via `druid.query.extraction.namespace`
* This is a rebase of https://github.com/b-slim/druid/tree/static_config_only
* Requires https://github.com/druid-io/druid-api/pull/37
* Requires https://github.com/metamx/java-util/pull/22
* Moves the puller logic to use a more standard workflow going through java-util helpers instead of re-writing the handlers for each impl
* General workflow goes like this: 1) LoadSpec makes sure the correct Puller is called with the correct parameters. 2) The Puller sets up general information like how to make an InputStream, how to find a file name (for .gz files for example), and when to retry. 3) CompressionUtils does most of the heavy lifting when it can
- Switch to using Druid parent POM
- Add required fields for Sonatype
- Common plugin versions and settings have been moved to the parent pom
- Cleanup artifacts and POMs for consistent formatting
- Remove org.hyperic.sigar dependency and update docs to reflect necessary jars to add at runtime when sigar is needed
Default behavior is as before.
Added documentation for how to enable synchronous logging for select chatty classes:
* io.druid.client.ServerInventoryView
* io.druid.client.BatchServerInventoryView
* io.druid.curator.inventory.CuratorInventoryManager
* com.metamx.http.client.pool.ChannelResourceFactory
