> Key: FLINK-19819
> URL: https://issues.apache.org/jira/browse/FLINK-19819
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / Common
> Reporter: Jingsong Lee
> Priority: Major
> Labels: stale-major
> Fix For: 1.13.0
>
>
> 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.
