Ari Ekmekji f0da6977a3 [Parallel L0-L1 Compaction Prep]: Giving Subcompactions Their Own State ... Summary: In prepration for running multiple threads at the same time during a compaction job, this patch assigns each subcompaction its own state (instead of sharing the one global CompactionState). Each subcompaction then uses this state to update its statistics, keep track of its snapshots, etc. during the course of execution. Then at the end of all the executions the statistics are aggregated across the subcompactions so that the final result is the same as if only one larger compaction had run. Test Plan: ./db_test ./db_compaction_test ./compaction_job_test Reviewers: sdong, anthony, igor, noetzli, yhchiang Reviewed By: yhchiang Subscribers: MarkCallaghan, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D43239		9 years ago
