Hello,
I read in the docs that `nodetool repair` should be regularly run unless no
delete is ever performed. In my app, I never delete, but I heavily use the
ttl feature. Should repair still be run regularly? Also, does repair take
less time if it is run regularly? If not, is there a way to
We observed the same behavior. During last repair the data distribution on
nodes was imbalanced as well resulting in one node bloating.

Arthur,
Yes, my use case for this Cassandra cluster is analytics. I am building a
google dapper (application tracing) like system. I collect application traces

TTL is effectively DELETE; you need to run a repair once every
gc_grace_seconds. If you don't, data might un-delete itself.
The undelete part is not true. btw: With CASSANDRA-4917 TTLed columns will
not even create a tombstone (assuming ttl gc_grace).
The rest of your mail I agree with :-)

How is it possible? Every replica has TTL, so it when it expires every
replica has tombstone. I don't see how you
