hjw updated FLINK-27539:
------------------------
Description:
custom_kafka is a cdc table
sql:
{code:java}
select DATE_FORMAT(window_end,'yyyy-MM-dd') as date_str,sum(money) as total,name
from TABLE(CUMULATE(TABLE custom_kafka,descriptor(createtime),interval '1'
MINUTES,interval '1' DAY ))
where status='1'
group by name,window_start,window_end;
{code}
Error
{code:java}
org.apache.flink.table.api.TableException: StreamPhysicalWindowAggregate
doesn't support consuming update and delete changes which is produced by node
TableSourceScan(table=[[default_catalog, default_database,custom_kafka]],
fields=[name, money, status,createtime,operation_ts])
{code}
But I found Group Window Aggregation is works when use cdc table
{code:java}
select DATE_FORMAT(TUMBLE_END(createtime,interval '10' MINUTES),'yyyy-MM-dd')
as date_str,sum(money) as total,name
from custom_kafka
where status='1'
group by name,TUMBLE(createtime,interval '10' MINUTES)
{code}
