Subject Re: read-repair and deletes / forgotten deletes
Date Mon, 01 Oct 2012 17:57:36 GMT
the 10 days is actually configurable... look into gc_grace.

Basically, you always need to run repair once per/gc_grace period.
You won't see empty/deleted rows go away until they're compacted away.

have to keep running read-repair manually all the time(god, I hope not as that should be automated
for deletes).
