Gyula Fora resolved FLINK-2664. ------------------------------- Resolution: Fixed > Remove partitioned states when set to null > ------------------------------------------ > > Key: FLINK-2664 > URL: https://issues.apache.org/jira/browse/FLINK-2664 > Project: Flink > Issue Type: Improvement > Components: Streaming > Reporter: Gyula Fora > Assignee: Gyula Fora > > Currently there is no way to remove a specific key from the partitioned state > stored at streaming operators, which can cause unnecessary state accumulation. > I suggest to remove the partitioned state for the current input when the > state is set to null, and upon next retrieval simply return the default > value. This allows the implementation of streaming programs that can garbage > collect their own unwanted state. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
