      Description

      Even with LCS you're going to frequently have 6 or 7 levels, with data in only one or two of those. With randomly distributed writes you'll have overlapping sstables in the other levels so having a bloom filter will be good to avoid hitting disk.

        Patch makes LCS default to 0.1 FP, which is half the size (5 buckets vs 10 per row) of the default 0.01 for STCS.
