>
> Key: FLINK-7617
> URL: https://issues.apache.org/jira/browse/FLINK-7617
> Project: Flink
> Issue Type: Improvement
> Components: Local Runtime
> Reporter: Jingsong Lee
> Assignee: Jingsong Lee
> Priority: Major
> Fix For: 1.4.0, 1.3.4
>
>
> 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.
