Subject Re: Unbalanced cluster with RandomPartitioner
Date Tue, 17 Jan 2012 18:51:19 GMT
We are running regular repairs, so I don't think that's the problem. 
And the data dir sizes match approx. the load from the nodetool.
Thanks for the advise, though.

Our keys are digits only, and all contain a few zeros at the same offsets. I'm not that familiar
with the md5 algorithm, but I doubt that it would generate 'hotspots' for those kind of keys,
right?
