Since we have a large amount of nodes in our > Cassandra fleet, not surprisingly, we encounter occasionally node status > going from up to down and up again. The problem is when the down node rejoins > the cluster after 15 minutes, it automatically adds already deleted data back > and causing zombie data. > our questions: > # Is there a way to not allow a down node to rejoin the cluster? > # or is there a way to configure rejoining node not adding stale data back > regardless of how long the node is down before rejoining > # or is there a way to auto clean up the data when rejoining ? > We know adding those data back is a conservative approach to avoid data loss > but in our specific case, we are not worried about deleted data being > revived.... we don’t have such use case. We really need a non-defaul option > to never add back deleted data on rejoining nodes. > this functionality will ultimately be a deciding factor on whether we can > continue with Cassandra. > > Please help! -- 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
