Describe the bug
We meet this problem in a long running application. When the queries, which contains get_json_object in Project or Filter, has been run multiple times, we find the performance is severely degraded. The flame graph shows that there is a problem of multi-threaded contention for locks, and the problem disappears when there is only one thread in executor.
