lt964709769 edited a comment on issue #3004: Improve RegisterPersistentWorker by bulk persistence to reduce cluster blocking URL: https://github.com/apache/skywalking/pull/3004#issuecomment-510367191 @peng-yongsheng Yes,The heartbeat is the main problem. Currently, there are 96 updates of service_inventory, 399 updates of service_instance_inventory, 93 updates of endpoint_inventory, and 17 updates of network_address_inventory every 3 seconds in our production environment. The 3 seconds param can be change to 1 min may alleviate the problem,but our system may scale to 10 times larger. This is why we do the optimization. Before the use of bulk, the online registration service was often blocked, which eventually led to the collapse of the whole cluster. After the use of bulk, the registration service ran stably.
