Externally-managed source of data that can be used to enrich the streaming events flowing from event sources. Two external sources are supported: tables and caches. FIXME need to refactor DataProvider and PullSource into a single API

Method Summary

java.util.Map	getCacheDataSource() Cache serving as a source, in the form of a map.
java.lang.String	getEventType() Source generates data of this type.
long	getExternalRowsThreshold() Returns the maximum allowed external rows to join with stream events return the threshold value
java.lang.String	getId() Returns the source identity
java.lang.String	getJDBCDataSource() Name of the data-source associated to this source, should it be a table.
java.lang.Class	getKeyClass() Returns key class for cache.
java.lang.String[]	getKeyPropertyNames() Return the key properties for cache.
java.lang.String	getTableName() Table name of the database table
