Subject Re: Should maintenance repairs be run on system related keyspaces?
Date Tue, 11 Aug 2015 14:59:07 GMT
Hi Ken,

As the "system" ks is "local" and repair is supposed to fix entropy, I
would say no... And you now know how to find out the answer for other
keyspace you include in "system related keyspaces" (If local, then no need,
else it depends on the fact that some entropy is acceptable or not, but I
would say, yes,  do it, system keyspaces should be small enough)...

"DESC keyspace system;

CREATE KEYSPACE system WITH replication = {

  'class': 'LocalStrategy'


I never read or even think about it myself, but I just wrote what makes
sense to me. If I am wrong, other will let you know.
