Rui Wang commented on CALCITE-3780: ----------------------------------- [~jmxie] Unfortunately I wasn't able to make it released into 1.25.0. So we can target to make it in release 1.26.0. I will try to cut a PR next week with the idea of moving the key descriptor to the last to make it optional. Let's see how people will think about it. > SESSION Table-valued Function > ----------------------------- > > Key: CALCITE-3780 > URL: https://issues.apache.org/jira/browse/CALCITE-3780 > Project: Calcite > Issue Type: Sub-task > Reporter: Rui Wang > Assignee: Rui Wang > Priority: Major > Fix For: 1.23.0 > > > We can create SESSION table-valued function to replace GROUP BY SESSION for > inactive gap session functionality: > {code:sql} > SELECT * > FROM TABLE SESSION ( > data => TABLE Bid , > timecol => DESCRIPTOR ( bidtime ) , > keycol => DESCRIPTOR(key), > inactive_gap => INTERVAL '10' MINUTES ) > {code} > > -- This message was sent by Atlassian Jira (v8.3.4#803005)
