  "message": "Use a shared heartbeat thread pool, don\u0027t create one for each lock\n\nBefore this change, each instance of the Lock class created a thread\npool of size one to run the heartbeat task. This didn\u0027t scale well as\nthe number of threads needed to maintain the heartbeat of N locks was N.\nThere are Git operations which lock a large number of refs and this\nwould have resulted in the large number of threads maintaining\nheartbeat for each lock.\n\nNow we use a dedicated thread pool of hardcoded size 10. We may make\nthis size configurable in the future if we see a need for that.\n\nChange-Id: Ia657a7a7ab80c5124bba40981e79c281e7381f53\n",
