Subject Meaning of 'nodetool repair has to run within GCGraceSeconds'
Date Thu, 30 Jun 2011 20:25:29 GMT
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.
