Charles Allen 86ede702b1 Add namespaced lookups as extensions ... * 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		2015-07-28 11:14:14 -07:00
