[jira] [Updated] (FLINK-6697) Add batch multi-window support
[ https://issues.apache.org/jira/browse/FLINK-6697?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Timo Walther updated FLINK-6697:
--------------------------------
Description:
Multiple consecutive windows on batch are not tested yet and I think they are also not supported, because the syntax is not defined for batch yet.
The following should be supported:
{code}
val t = table
.window(Tumble over 2.millis on 'rowtime as 'w)
.groupBy('w)
.select('w.rowtime as 'rowtime, 'int.count as 'int)
.window(Tumble over 4.millis on 'rowtime as 'w2)
.groupBy('w2)
.select('w2.rowtime, 'w2.end, 'int.count)
{code}
