             Summary: Take codegen cache memory into account for admission controller
                 Key: IMPALA-11786
                 URL: https://issues.apache.org/jira/browse/IMPALA-11786
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Yida Wu
            Assignee: Yida Wu


Currently admission controller is not aware of the memory usage of the codegen cache, and the codegen cache is long-running and damon-level, this may lead to more allocation failures during heavy workload scenario when the available memory is running out. One solution is to subtract the codegen cache capacity from the available memory that admission controller can use when initialization, so that the admission controller would take account of the usage of codegen cache since the beginning.
