> Attachments: HybridCompactionStrategy.java

> 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.
