Description

Currently IBatchSpout, IOpaquePartitionSpout}, ITridentSpout and IPartitionedSpout are all top-level interfaces. The lowest common ancestor of their parent interface is Serializable. There is no clear, single interface in Trident to mark these class are spouts / data sources. The abstraction is beneficial when components on top of Trident (e.g. StormSQL) need a notion of data source.

This jira proposes to tags all the spouts above with a common marker interface.
