> Created new blocking compaction (added compaction type "optimize") by adding a lock request on the compaction's transaction. It works mostly like mmMajorCompaction and writes files w/o row_IDs. I have added an additional table property to provide optimize columns that is used by the compactor to cluster the data by.
