Jay Zhuang created CASSANDRA-15141: -------------------------------------- Summary: RemoveNode takes long time and blocks gossip stage Key: CASSANDRA-15141 URL: https://issues.apache.org/jira/browse/CASSANDRA-15141 Project: Cassandra Issue Type: Improvement Components: Cluster/Gossip, Cluster/Membership Reporter: Jay Zhuang Assignee: Jay Zhuang
This function [{{getAddressReplicas()}}|https://github.com/apache/cassandra/blob/7df67eff2d66dba4bed2b4f6aeabf05144d9b057/src/java/org/apache/cassandra/service/StorageService.java#L3002] during removenode and decommission is slow for large vnode cluster with NetworkTopologyStrategy. As it needs to build whole replications map for every token range. In one of our cluster (> 1k nodes), it takes about 20 seconds for each NetworkTopologyStrategy keyspace, so the total time to process a removenode message takes at least 80 seconds (20 * 4: 3 system keyspaces, 1 user keyspace). It blocks the heartbeat propagation and causes false down node. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
