Hi all,

  Sorry for the interruption. But I need help.


   Due to specific reasons of our use case,  we have gc grace on the order of 
10 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.

Thanks again,
