After that, can consider printing the thread context recorded in ThreadContext, but it may be useless, because ThreadMemTracker will accumulate a batch of memory requests to call consume, and the memory request mem_limit_exceeded may be small. It may be more effective to print the status of the query and all instance trackers. -- This is an automated message from the Apache Git Service.
