EventSource

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

Event source captures data that is essentially immutable - like user clicks, impressions etc. It has two parts, an offline table and an online topic. The term fact table from star-schema also maps to this concepts. But lacks a notion of topic.

:param table: Table currently needs to be a 'ds' (date string - yyyy-MM-dd) partitioned hive table. Table names can contain subpartition specs, example db.table/system=mobile/currency=USD :param topic: Topic is a kafka table. The table contains all the events historically came through this topic. :param query: 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.
