Summary: Support count window with the window TVF in planner
Key: FLINK-24002
URL: https://issues.apache.org/jira/browse/FLINK-24002
Project: Flink
Issue Type: Sub-task
Components: Table SQL / Planner
Affects Versions: 1.15.0
Reporter: JING ZHANG
For a long time, count window is supported in Table API, but not supported in
SQL.
With the new window TVF syntax, we can also introduce a new window function for
count window.
For example, the following TUMBLE_ROW assigns windows in 10 row-count interval.
{panel}
{panel}
|{{SELECT}} {{*}}
{{FROM}} {{TABLE}}{{(}}
{{ }}{{TUMBLE_ROW(}}
{{ }}{{data => }}{{TABLE}} {{inputTable,}}
{{ }}{{timecol => DESCRIPTOR(timecol),}}
{{ }}{{size}} {{=> 10));}}|
