> Key: FLINK-22037
> URL: https://issues.apache.org/jira/browse/FLINK-22037
> Project: Flink
> Issue Type: Bug
> Components: Benchmarks
> Affects Versions: 1.13.0
> Reporter: Zhilong Hong
> Assignee: Zhilong Hong
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.13.0

>
> We find that the {{BlockingQueue}} that used to preserve
> {{TaskDeploymentDescriptors}} which are never used later. Since a
> {{TaskDeploymentDescriptor}} would cost massive heap memory, it may introduce
> unnecessary garbage collection and make the result of benchmarks related to
> deployment unstable. Therefore, we think it's better to remove the redundant
> blocking queue in {{DeployingTasksBenchmarkBase}}.
