Subject Re: (unofficial) Community Poll for Production Operators : Repair
Date Wed, 15 May 2013 09:33:40 GMT
Hi Alain,

have you had a look at the following tickets?

CASSANDRA-4905 - Repair should exclude gcable tombstones from merkle-tree
computation
CASSANDRA-4932 - Agree on a gcbefore/expirebefore value for all replica
during validation compaction
CASSANDRA-4917 - Optimize tombstone creation for ExpiringColumns
CASSANDRA-5398 - Remove localTimestamp from merkle-tree calculation (for
tombstones)

Imho these should reduce the over-repair to some degree. Especially when
using TTL. Some of them are already fixed in 1.2. The rest will (hopefully)
follow :-)

cheers,
Christian
