Summary: While doing forward iterating, if current key is merge, internal iterator position is placed to the next key. If Prev() is called now, needs to do extra Prev() to recover the location.

Summary: The compact files API had a bug where some overlapping files are not added. These are files which overlap with files which were added to the compaction input files, but not to the original set of input files. This happens only when there are more than two levels involved in the compaction. An example will illustrate this better. Level 2 has 1 input file 1.sst which spans [20,30]. Level 3 has added file 2.sst which spans [10,25] Level 4 has file 3.sst which spans [35,40] and input file 4.sst which spans [46,50]. The existing code would not add 3.sst to the set of input_files because it only becomes an overlapping file in level 4 and it wasn't one in level 3. When installing the results of the compaction, 3.sst would overlap with output file from the compact files and result in the assertion in version_set.cc:1130 // Must not overlap assert(level <= 0 || level_files->empty() || internal_comparator_->Compare( (*level_files)[level_files->size() - 1]->largest, f->smallest) < 0); This change now adds overlapping files from the current level to the set of input files also so that we don't hit the assertion above.

Summary: As of now compactions involving files from Level 0 and Level 1 are single threaded because the files in L0, although sorted, are not range partitioned like the other levels. This means that during L0-L1 compaction each file from L1 needs to be merged with potentially all the files from L0. This attempt to parallelize the L0-L1 compaction assigns a thread and a corresponding iterator to each L1 file that then considers only the key range found in that L1 file and only the L0 files that have those keys (and only the specific portion of those L0 files in which those keys are found). In this way the overlap is minimized and potentially eliminated between different iterators focusing on the same files. The first step is to restructure the compaction logic to break L0-L1 compactions into multiple, smaller, sequential compactions. Eventually each of these smaller jobs will be run simultaneously. Areas to pay extra attention to are # Correct aggregation of compaction job statistics across multiple threads # Proper opening/closing of output files (make sure each thread's is unique) # Keys that span multiple L1 files # Skewed distributions of keys within L0 files Test Plan: Make and run db_test (newer version has separate compaction tests) and compaction_job_stats_test Reviewers: igor, noetzli, anthony, sdong, yhchiang Reviewed By: yhchiang Subscribers: MarkCallaghan, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D42699
