--------------------------------------------------
Hi [~martijnvisser], Yes I want to run flink on bounded mysql database using
Table API connector.
Lets consider :
I have two tables TABLE_A and TABLE_B.
I need to join both tables and get the records whose id column matches.
But currently flink selects all the records from both table and perform joins
in-memory. But I want to push this join to underlying SQL Engine. Is this
possible ?
