Summary: Support to join a static table in streaming mode
Key: FLINK-16323
URL: https://issues.apache.org/jira/browse/FLINK-16323
Project: Flink
Issue Type: New Feature
Components: Table SQL / API, Table SQL / Planner
Reporter: Jark Wu
Currently, we already support to join a stream and a bounded stream using
reguar join. However, this will be tranlsated into stream-stream join which is
not efficient, because it will output early results and maybe retracted
afterwards.
A better and native support will be using a special temporal join operator
which will block the streaming side until all the static table data is loaded.
This can help users to join a huge table, e.g. MySQL table with billion records
but changes little.
