---------------------------------

             Summary: GSoC project: Batch and Streaming integration through new operators
and unified API
                 Key: FLINK-1503
                 URL: https://issues.apache.org/jira/browse/FLINK-1503
             Project: Flink
          Issue Type: New Feature
          Components: Java API, Scala API, Streaming
            Reporter: Gyula Fora
            Priority: Minor


Currently the Flink batch and streaming API-s (java and scala) and runtimes work independently
from each other without operators to allow interactions between DataStreams and DataSets in
a fault-tolerant manner.

The goal is to modify the execution environments and the runtime layer to allow these interactions.

Possible runtime changes to add:
-Interaction through intermediate files
-Interaction by connection the execution graphs 

Possible new operators implement:
-Converting a dataset to a datastream (either by directly streaming in the results or periodically
executing the dataset transformations)
-Hash joining a datastream with a dataset by key
-Other binary operators with streams and sets

The implementations should work with the fault tolerance mechanism provided by then (exaclty-once
or at-least-once guarantees).
