Hello community,
I get an error response when I just try to use the ksql example from the confluent page:
CREATE TABLE foo AS
SELECT * FROM bar
WINDOW TUMBLING (size 10 seconds)
EMIT CHANGES;
Response:
"Could not determine output schema for query due to error: Line: 3, Col: 8: WINDOW clause requires a GROUP BY clause. "
Why do I net a group by clause there?
Thank you in advance!
