[jira] [Created] (FLINK-31466) Backport "FilterJoinRule misses opportunity to push filter to semijoin input" to FlinkFilterJoinRule

Sergey Nuyanzin created FLINK-31466:
---------------------------------------

             Summary: Backport "FilterJoinRule misses opportunity to push filter to semijoin input" to FlinkFilterJoinRule
                 Key: FLINK-31466
                 URL: https://issues.apache.org/jira/browse/FLINK-31466
             Project: Flink
          Issue Type: Improvement
            Reporter: Sergey Nuyanzin


In https://issues.apache.org/jira/browse/CALCITE-4499 there has been done an optimization.
Since Flink has it's own copy of slightly changed {{FilterJoiRule}} this optimization does not come with 1.28 update.

The idea is to apply this change to {{FlinkFilterJoinRule}}
