> If LCS gets behind, read performance deteriorates as we have to check bloom 
> filters on man sstables in L0.  For wide rows, this can mean having to seek 
> for each one since the BF doesn't help us reject much.
> Performing size-tiered compaction in L0 will mitigate this until we can catch 
> up on merging it into higher levels.
