Gyula Fora created FLINK-2283: --------------------------------- Summary: Make grouped reduce/fold/aggregations stateful using Partitioned state Key: FLINK-2283 URL: https://issues.apache.org/jira/browse/FLINK-2283 Project: Flink Issue Type: Improvement Components: Streaming Affects Versions: 0.10 Reporter: Gyula Fora Priority: Minor
Currently the inner state of the grouped aggregations are not persisted as an operator state. These operators should be reimplemented to use the newly introduced partitioned state abstractions which will make them fault tolerant and scalable for the future. A suggested implementation would be to use a stateful mapper to implement the desired behaviour. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
