Gyula Fora created FLINK-1503: --------------------------------- 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). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
