vvysotskyi opened a new pull request #1887: DRILL-7372: MethodAnalyzer consumes too many memory
URL: https://github.com/apache/drill/pull/1887
 
 
   Jira: [DRILL-7372](https://issues.apache.org/jira/browse/DRILL-7372).
   
   - Replaced `Set<Integer>` with `BitSet` - it allowed to reduce heap usage significantly.
   - Avoided copying `localVariablesSet` and `labelsStack` from the source frame when a new frame is created since the branch-sensitive analysis was already done for a source frame.
