-------------------------------------

             Summary: how to persist flink table like spark persist dataset
                 Key: FLINK-29780
                 URL: https://issues.apache.org/jira/browse/FLINK-29780
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / API
            Reporter: qingwei zhong


I have code:

table1 = table...

table2 = table1....

table3 = table1...

 

How many times would (table1 = table...) be executed?

Once or twice?

I think it executes once, but it actually executes twice, so how do I make it only execute once
