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.
