Jark Wu created FLINK-16332: ------------------------------- Summary: Support un-ordered mode for async lookup join Key: FLINK-16332 URL: https://issues.apache.org/jira/browse/FLINK-16332 Project: Flink Issue Type: New Feature Components: Table SQL / API, Table SQL / Planner Reporter: Jark Wu
Currently, we only support "ordered" mode for async lookup join. Because the ordering in streaming SQL is very important, the accumulate and retract messages shoudl be in ordered. If messages are out of order, the result will be wrong. The "un-ordered" mode can be enabled by a job configuration. But it will be a prefered option. Only if it doesn't affect the order of acc/retract messages (e.g. it is just an append-only stream), the "un-ordered" mode will be enabled. -- This message was sent by Atlassian Jira (v8.3.4#803005)
