             Summary: Support lazy evaluation in Flink SQL
                 Key: FLINK-22983
                 URL: https://issues.apache.org/jira/browse/FLINK-22983
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / Runtime
    Affects Versions: 1.13.1
            Reporter: Maciej Bryński


Currently when there is logical condition in Flink SQL we're calculating all arguments.

Example:
{code:java}
SELECT n > 0 AND n > 100 {code}
This will trigger both checks even when n > 0.

Same for AND
{code:java}
SELECT n > 0 AND n > 100 {code}
will trigger n > 100 check for n <= 0

 

I think we should support lazy condition evaluation.
