---------------------------------------
Summary: Is there a way to auto-clean up data whenever an old node
rejoins the cluster
Key: CASSANDRA-15190
URL: https://issues.apache.org/jira/browse/CASSANDRA-15190
Project: Cassandra
Issue Type: Bug
Reporter: Yuping Wang
Due to specific reasons of our use case, we have gc grace to 15 minutes
instead of default 10 days. 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!
