             Summary: support consuming update and delete changes In Windowing 
TVFs
                 Key: FLINK-27539
                 URL: https://issues.apache.org/jira/browse/FLINK-27539
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / API
    Affects Versions: 1.15.0
            Reporter: hjw


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

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])

But I found Group Window Aggregation is works when use cdc table

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)
