Mark Callaghan 70c42bf05f Adds DB::GetNextCompaction and then uses that for rate limiting db_bench ... Summary: Adds a method that returns the score for the next level that most needs compaction. That method is then used by db_bench to rate limit threads. Threads are put to sleep at the end of each stats interval until the score is less than the limit. The limit is set via the --rate_limit=$double option. The specified value must be > 1.0. Also adds the option --stats_per_interval to enable additional metrics reported every stats interval.
