Re: Flink sql joined with dimtable from mysql
It was not super clean on what you did. But from your description, the join
was not correct initially because existing MySQL data was not seen by Flink
yet. Later when updates are seen by Flink, the result will be correct. A
better place for such question is probably on the user mailing list.
