> URL: https://issues.apache.org/jira/browse/FLINK-19819

> Priority: Minor
> Labels: auto-deprioritized-major
> Fix For: 1.14.0
>
>
> User requirement:
> Users need to look at a few random pieces of data in a table to see what the
> data looks like. So users often use the SQL:
> "select * from table limit 10"
> For a large table, expect to end soon because only a few pieces of data are
> queried.
> For DataStream or BoundedStream, they are push based execution models, so the
> downstream cannot control the end of source operator.
> We need push down limit to source operator, so that source operator can end
> early.
