Subject Re: partition sizes reported by nodetool tablehistograms

Its the decompressed size of the partitions. Each sstable has stats
component that contains histograms for the size and number of columns in
the partitions (among other things, can see with sstablemetadata tool),
tablehistograms merges it for each sstable and gives the results.
