Summary: Too many caches can block discovery Key: IGNITE-12844 URL: https://issues.apache.org/jira/browse/IGNITE-12844 Project: Ignite Issue Type: Bug Reporter: Philipp Masharov Assignee: Philipp Masharov Fix For: 2.9 Several thousand caches send metrics in each discovery message. Check implementation of `TcpDiscoveryMetricsUpdateMessage` This behavior increases processing time and raises message size. As a result, the discovery worker is busy and the queue pool is growing. We need to notify about the possible issue and print suggestion, for example, `-DIGNITE_DISCOVERY_DISABLE_CACHE=true` if it can help. Assumes to print WARN message once, for example, if TcpDiscoveryMetricsUpdateMessage consists of more than 500 CacheMetricsSnaphot instances. -- This message was sent by Atlassian Jira (v8.3.4#803005)
