> 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).
