Subject 2x storage
Date Fri, 25 Feb 2011 17:22:49 GMT
I read in some cassandra notes that each node should be allocated
twice the storage capacity you wish it to contain. I think the reason
was during compaction another copy of SSTables have to be made before
the original ones are discarded.

Can someone confirm if that is actually true ? During compaction,
don't just a few SSTables are involved. Why should it be twice the
full storage ? If I keep some buffer, it really means that I can use
40% or so space only.

Many thanks.
