[jira] [Created] (FLINK-22037) Remove the redundant blocking queue from DeployingTasksBenchmarkBase

Zhilong Hong created FLINK-22037:
------------------------------------

             Summary: Remove the redundant blocking queue from DeployingTasksBenchmarkBase
                 Key: FLINK-22037
                 URL: https://issues.apache.org/jira/browse/FLINK-22037
             Project: Flink
          Issue Type: Bug
          Components: Benchmarks, Runtime / Coordination
    Affects Versions: 1.13.0
            Reporter: Zhilong Hong
             Fix For: 1.13.0


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