      Implement log blobs · 0307c5fe
      Jim Paton 提交于
      Summary:
      This patch adds the ability for the user to add sequences of arbitrary data (blobs) to write batches. These blobs are saved to the log along with everything else in the write batch. You can add multiple blobs per WriteBatch and the ordering of blobs, puts, merges, and deletes are preserved.
      
      Blobs are not saves to SST files. RocksDB ignores blobs in every way except for writing them to the log.
      
      Before committing this patch, I need to add some test code. But I'm submitting it now so people can comment on the API.

      Virtualize SkipList Interface · 52d7ecfc
      Jim Paton 提交于
      Summary: This diff virtualizes the skiplist interface so that users can provide their own implementation of a backing store for MemTables. Eventually, the backing store will be responsible for its own synchronization, allowing users (and us) to experiment with different lockless implementations.
      
      Test Plan:
      make clean
      make -j32 check
      ./db_stress

      [Rocksdb] Support Merge operation in rocksdb · 05e88540
      Haobo Xu 提交于
      Summary:
      This diff introduces a new Merge operation into rocksdb.
      The purpose of this review is mostly getting feedback from the team (everyone please) on the design.
      
      Please focus on the four files under include/leveldb/, as they spell the client visible interface change.
      include/leveldb/db.h
      include/leveldb/merge_operator.h
      include/leveldb/options.h
      include/leveldb/write_batch.h
      
      Please go over local/my_test.cc carefully, as it is a concerete use case.
      
      Please also review the impelmentation files to see if the straw man implementation makes sense.
      
      Note that, the diff does pass all make check and truly supports forward iterator over db and a version
      of Get that's based on iterator.
      
      Future work:
      - Integration with compaction
      - A raw Get implementation
      
      I am working on a wiki that explains the design and implementation choices, but coding comes
      just naturally and I think it might be a good idea to share the code earlier. The code is
      heavily commented.
      
      Test Plan: run all local tests

      A number of fixes: · 36a5f8ed
      Hans Wennborg 提交于
      - Replace raw slice comparison with a call to user comparator.
        Added test for custom comparators.
      
      - Fix end of namespace comments.
      
      - Fixed bug in picking inputs for a level-0 compaction.
      
        When finding overlapping files, the covered range may expand
        as files are added to the input set.  We now correctly expand
        the range when this happens instead of continuing to use the
        old range.  For example, suppose L0 contains files with the
        following ranges:
      
            F1: a .. d
            F2:    c .. g
            F3:       f .. j
      
        and the initial compaction target is F3.  We used to search
        for range f..j which yielded {F2,F3}.  However we now expand
        the range as soon as another file is added.  In this case,
        when F2 is added, we expand the range to c..j and restart the
        search.  That picks up file F1 as well.
      
        This change fixes a bug related to deleted keys showing up
        incorrectly after a compaction as described in Issue 44.
