  "message": "Improve locking to handle stale locks\n\nLocks are a mechanism to ensure exclusive usage of the locked\nresource. Here we provide a Spanner-specific implementation of\nlocks which are used from the global-refdb module.\n\nTo ensure lock freshness we use heartbeats. Stale locks can be\nreclaimed.\n\nSee Documentation/locks.md for more details.\n\nChange-Id: Idbe3b457327d05fda2c2352bab2be27411346965\n",
