> FIFO compaction policy selects only files which have all cells expired. The column family
MUST have non-default TTL. 
> Essentially, FIFO compactor does only one job: collects expired store files.
> Because we do not do any real compaction, we do not use CPU and IO (disk and network),
we do not evict hot data from a block cache. The result: improved throughput and latency both
write and read.
