Recently, we have observed serious event blocking in RM event dispatcher queue. After analysis of RM event monitoring data and RM event processing logic, we found that the proportion of RMNodeStatusEvent is less than other events, but the overall processing time of it is more than other events. Meanwhile, RM event processing is in a single-thread mode, and It results in the decrease of RM's performance. So we proposed a RM multi-thread event processing mechanism to improve RM performance. Is this mechanism feasible?
