[jira] [Created] (IMPALA-6197) Instrument our locks to track contention

Lars Volker created IMPALA-6197:
-----------------------------------

             Summary: Instrument our locks to track contention
                 Key: IMPALA-6197
                 URL: https://issues.apache.org/jira/browse/IMPALA-6197
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Lars Volker


We should add instrumentation to our locks (or switch to an alternative like [absl::mutex|https://abseil.io/about/design/mutex]) to enable profiling of lock contention (see [absl::RegisterMutexProfiler()|https://github.com/abseil/abseil-cpp/blob/master/absl/synchronization/mutex.h#L933].
