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).
