-------------------------------

             Summary: Support LookupableTableSource for CsvTableSource
                 Key: FLINK-12978
                 URL: https://issues.apache.org/jira/browse/FLINK-12978
             Project: Flink
          Issue Type: Task
          Components: Table SQL / API
            Reporter: Jark Wu


CsvTableSource is a highly used source in demo and testing. It will be great if it also supports LookupableTableSource so that it can be used in temporal table join (act like a external dimension table).

 

The lookupable csv source implementation should be tested in blink planner, because currently only blink support lookup.
