Subject random keys and overlapping key ranges in SSTables
Date Sat, 31 Dec 2011 10:08:54 GMT

If the rows are updated by random keys, then most of the SSTables will have overlapping 
key ranges, right? Then for each read, Cassandra will go through all the SSTables (or
one SSTable in each level for the leveled compaction strategy)? How to deal with this
