EntitySource

class EntitySource extends TBase[EntitySource, _Fields] with Serializable with Cloneable with Comparable[EntitySource]

Entity Sources represent data that gets mutated over-time - at row-level. This is a group of three data elements. snapshotTable, mutationTable and mutationTopic. mutationTable and mutationTopic are only necessary if we are trying to create realtime or point-in-time aggregations over these sources. Entity sources usually map 1:1 with a database tables in your OLTP store that typically serves live application traffic. When mutation data is absent they map 1:1 to dim tables in star schema.

:param snapshotTable: Table currently needs to be a 'ds' (date string - yyyy-MM-dd) partitioned hive table. :param mutationTable: Topic is a kafka table. The table contains all the events historically came through this topic. :param mutationTopic: The logic used to scan both the table and the topic. Contains row level transformations and filtering expressed as Spark SQL statements. :param isCumulative: If each new hive partition contains not just the current day's events but the entire set of events since the begininng. The key property is that the events are not mutated across partitions.
