[jira] [Updated] (FLINK-8689) Add runtime support of distinct
filter using MapView for GenerateAggregation
[ https://issues.apache.org/jira/browse/FLINK-8689?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rong Rong updated FLINK-8689:
-----------------------------
Description:
This should add distinct aggregate function support to codegen for `AggregateCall`, where `isDistinct` fields is set to true.
This can be verified using the following SQL, which is not currently producing correct results.
{code:java}
SELECT
a,
SUM(b) OVER (PARTITION BY a ORDER BY proctime ROWS BETWEEN 5 PRECEDING AND CURRENT ROW)
FROM
MyTable{code}
