---------------------------------------

             Summary: Consider setting the number of TM CPU cores to the actual number of cores
                 Key: FLINK-17546
                 URL: https://issues.apache.org/jira/browse/FLINK-17546
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Configuration
            Reporter: Andrey Zagrebin


So far we do not use CPU cores resource in TaskExecutorResourceSpec. It was a preparation for dynamic slot/resource allocation (FLINK-14187). It is not fully clear how Flink or users would define the number of cores. We could consider setting the number of TM CPU cores to the actual number of cores by default, e.g. got somehow from OS in standalone or container configuration.
