> Key: FLINK-2534
> URL: https://issues.apache.org/jira/browse/FLINK-2534
> Project: Flink
> Issue Type: Improvement
> Components: Local Runtime

> Original Estimate: 168h

> I found some improved code in CompactingHashTable.java since this code will execute many times when flink runs.
> In my opinion, some codes in "for" and "while" can be optimized to reduce the times of execution and it is effective to increase the performance.
> For example, the code following:
> 'while(numBuckets % numPartitions != 0) {
> numBuckets++;
> }'
> can be optimized into a formula:
> numBuckets += numPartitions - (numBuckets % numPartitions);
