[jira] [Created] (FLINK-7617) Remove string format in BitSet to improve the performance of BuildSideOuterjoin

Jingsong Lee created FLINK-7617:
-----------------------------------

             Summary: Remove string format in BitSet to improve the performance of BuildSideOuterjoin
                 Key: FLINK-7617
                 URL: https://issues.apache.org/jira/browse/FLINK-7617
             Project: Flink
          Issue Type: Improvement
          Components: Local Runtime
            Reporter: Jingsong Lee


When using BuildSideOuterjoin, will frequently call Bitset.set and get, there will be

Preconditions.checkArgument (index <bitLength && index> = 0,
String.format ("Input Index [% d] is larger than BitSet available size [% d].", Index, bitLength));

Of the check, String.format will lead to a sharp decline performance.
