I am little confused of the reason why nodetool repair has to run within GCGraceSeconds.
The documentation at: http://wiki.apache.org/cassandra/Operations#Frequency_of_nodetool_repair is not very clear to me. How can a delete be 'unforgotten' if I don't run nodetool repair? (I understand that if a node is down for more than GCGraceSeconds, I should not get it up without resynching is completely. Otherwise deletes may reappear.http://wiki.apache.org/cassandra/DistributedDeletes ) But not sure how exactly nodetool repair ties into this mechanism of distributed deletes. Thanks for any clarifications.
