dalongliu created FLINK-29551: --------------------------------- Summary: Improving adaptive hash join by using sort merge join strategy per partition instead of all partitions Key: FLINK-29551 URL: https://issues.apache.org/jira/browse/FLINK-29551 Project: Flink Issue Type: Improvement Components: Table SQL / Runtime Affects Versions: 1.16.0 Reporter: dalongliu Fix For: 1.17.0
Currently, Regarding adaptive hash join, when falling back to sort-merge join, it sorts all partitions globally, however, due to the keys of each partition are disjoint, we can sort it per partition, which can improve the performance. -- This message was sent by Atlassian Jira (v8.20.10#820010)
