We propose an optimization method adaptive hash join for the batch join scenario, hoping to integrate the advantages of sorted-merge join and hash join according to the characteristics of runtime data. The adaptive hash join will try to use hash join firstly, if it failed, will fallback to sort merge join. -- This message was sent by Atlassian Jira (v8.20.1#820001)
