Reynold Xin updated SPARK-10815:
--------------------------------
Description:
The existing (in 2.0) source/sink interface for structured streaming depends on
RDDs. This dependency has two issues:
1. The RDD interface is wide and difficult to stabilize across versions. This
is similar to point 1 in https://issues.apache.org/jira/browse/SPARK-15689.
Ideally, a source/sink implementation created for Spark 2.x should work in
Spark 10.x, assuming the JVM is still around.
2. It is difficult to swap in/out a different execution engine.
The purpose of this ticket is to create a stable interface that addresses the
above two.
