godfrey he created FLINK-12079: ---------------------------------- Summary: Add support for generating optimized logical plan for join on batch Key: FLINK-12079 URL: https://issues.apache.org/jira/browse/FLINK-12079 Project: Flink Issue Type: New Feature Components: Table SQL / Planner Reporter: godfrey he Assignee: godfrey he
Currently, there are 3 types of batch physical join nodes: {{BatchExecHashJoin}}, {{BatchExecSortMergeJoin}} and {{BatchExecNestedLoopJoin}}. This issue aims to add rules to convert logical join to appropriate physical join. a logical join * can be converted to {{BatchExecHashJoin}} if join keys are not empty and ShuffleHashJoin or BroadcastHashJoin are enabled, * can be converted to {{BatchExecSortMergeJoin}} if join keys are not empty and SortMergeJoin is enabled, * can be converted to {{BatchExecNestedLoopJoinRule}} if NestedLoopJoin is enabled or one of join input sides returns at most a single row. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
