Yueh-Hsuan Chiang 14d0bfa429 Add DBOptions::skip_sats_update_on_db_open ... Summary: UpdateAccumulatedStats() is used to optimize compaction decision esp. when the number of deletion entries are high, but this function can slowdown DBOpen esp. in disk environment. This patch adds DBOptions::skip_sats_update_on_db_open, which skips UpdateAccumulatedStats() in DB::Open() time when it's set to true.
