yisha zhou commented on FLINK-19822: ------------------------------------ Hi [~godfreyhe]! We gonna utilize multipleInputOperator in stream mode and this issue is the prerequisite of it. Could you please follow up this issue or assign it to someone else? > Remove redundant shuffle for streaming > -------------------------------------- > > Key: FLINK-19822 > URL: https://issues.apache.org/jira/browse/FLINK-19822 > Project: Flink > Issue Type: Improvement > Components: Table SQL / Planner > Reporter: godfrey he > Priority: Not a Priority > Labels: auto-deprioritized-major, auto-deprioritized-minor, > auto-unassigned, pull-request-available > > This is similar > [FLINK-12575|https://issues.apache.org/jira/browse/FLINK-12575], we could > implement {{satisfyTraits}} method for stream nodes to remove redundant > shuffle. This could add more possibilities that more operators can be merged > into multiple input operator. > Different batch, stream operators require the shuffle keys and the state keys > must be exactly the same, otherwise the state may be not correct. > We only support a few operators in this issue, such as Join and regular > Aggregate. Other operators will be supported in the future. -- This message was sent by Atlassian Jira (v8.20.10#820010)
