Hi, I have flink-sql job that makes 21 left joins and 14 inner joins and currently facing some performance issue. Just wondering if join order between tables makes the difference in DAG that flinks generate?? Example:
Copy code
table1 inner join table2 ... inner join table10
vs
Copy code
table10 inner join table9 inner join table8... inner join table1
where volume of data increases from table1... table10 ?
