Xintong Song updated FLINK-19819: --------------------------------- Fix Version/s: (was: 1.14.0) 1.15.0 > SourceReaderBase supports limit push down > ----------------------------------------- > > Key: FLINK-19819 > URL: https://issues.apache.org/jira/browse/FLINK-19819 > Project: Flink > Issue Type: Improvement > Components: Connectors / Common > Reporter: Jingsong Lee > Priority: Minor > Labels: auto-deprioritized-major > Fix For: 1.15.0 > > > User requirement: > Users need to look at a few randomĀ 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 canĀ end > early. -- This message was sent by Atlassian Jira (v8.3.4#803005)
