    • DfsReaderOptions

      public DfsReaderOptions()
      Create a default reader configuration.

  • Method Details

    • getDeltaBaseCacheLimit

      public int getDeltaBaseCacheLimit()
      Get maximum number of bytes to hold in per-reader DeltaBaseCache.
      Returns:
      maximum number of bytes to hold in per-reader DeltaBaseCache.

    • setDeltaBaseCacheLimit

      public DfsReaderOptions setDeltaBaseCacheLimit(int maxBytes)
      Set the maximum number of bytes in the DeltaBaseCache.
      Parameters:
      maxBytes - the new limit.
      Returns:
      this

    • getStreamFileThreshold

      public int getStreamFileThreshold()
      Get the size threshold beyond which objects must be streamed.
      Returns:
      the size threshold beyond which objects must be streamed.

    • setStreamFileThreshold

      public DfsReaderOptions setStreamFileThreshold(int newLimit)
      Set new byte limit for objects that must be streamed.
      Parameters:
      newLimit - new byte limit for objects that must be streamed. Objects smaller than this size can be obtained as a contiguous byte array, while objects bigger than this size require using an ObjectStream.
      Returns:
      this

    • getStreamPackBufferSize

      public int getStreamPackBufferSize()
      Get number of bytes to use for buffering when streaming a pack file during copying.
      Returns:
      number of bytes to use for buffering when streaming a pack file during copying. If 0 the block size of the pack is used.

    • setStreamPackBufferSize

      public DfsReaderOptions setStreamPackBufferSize(int bufsz)
      Set new buffer size in bytes for buffers used when streaming pack files during copying.
      Parameters:
      bufsz - new buffer size in bytes for buffers used when streaming pack files during copying.
      Returns:
      this

    • shouldLoadRevIndexInParallel

      public boolean shouldLoadRevIndexInParallel()
      Check if reverse index should be loaded in parallel.
      Returns:
      true if reverse index is loaded in parallel for bitmap index.

    • setLoadRevIndexInParallel

      public DfsReaderOptions setLoadRevIndexInParallel(boolean loadRevIndexInParallel)
      Enable (or disable) parallel loading of reverse index.
      Parameters:
      loadRevIndexInParallel - whether to load reverse index in parallel.
      Returns:
      this

    • shouldUseObjectSizeIndex

      public boolean shouldUseObjectSizeIndex()
      Use the object size index if available.
      Returns:
      true if the reader should try to use the object size index. if false, the reader ignores that index.

    • setUseObjectSizeIndex

      public DfsReaderOptions setUseObjectSizeIndex(boolean useObjectSizeIndex)
      Set if the reader should try to use the object size index
      Parameters:
      useObjectSizeIndex - true to use it, false to ignore the object size index
      Returns:
      this

    • shouldUseMidxBitmaps

      public boolean shouldUseMidxBitmaps()
      Use bitmaps in the midx if available.
      Returns:
      true if a midx pack should use its own bitmaps. false to fallback to GC bitmaps.

    • setUseMidxBitmaps

      public DfsReaderOptions setUseMidxBitmaps(boolean useMidxBitmaps)
      Set if the midx packs should use their bitmaps or fallback to bitmaps in GC pack.
      Parameters:
      useMidxBitmaps - useMidxBitmaps to set
      Returns:
      this

    • fromConfig

      public DfsReaderOptions fromConfig(Config rc)
      Update properties by setting fields from the configuration.

      If a property is not defined in the configuration, then it is left unmodified.

      Parameters:
      rc - configuration to read properties from.
      Returns:
      this
