Subject Re: Deleted columns reappear after "repair"
Date Tue, 24 Mar 2015 17:05:57 GMT
Hi Duncan,

Thanks for the response!

I can try increasing gc_grace_seconds and run repair on all nodes. It does
not make sense though why all *new* deletes (for the same column that
resurrects after repair) I do are forgotten as well after repair? Doesn't
Cassandra insert a new tombstone every time delete happens?

Also, how do I find out the value to set gc_grace_seconds to?
