-----------------------------------
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.
