      public CompactionOptionsFIFO()

  • Method Details

    • setMaxTableFilesSize

      public CompactionOptionsFIFO setMaxTableFilesSize(long maxTableFilesSize)
      Once the total sum of table files reaches this, we will delete the oldest table file

      Default: 1GB

      Parameters:
      maxTableFilesSize - The maximum size of the table files
      Returns:
      the reference to the current options.

    • maxTableFilesSize

      public long maxTableFilesSize()
      Once the total sum of table files reaches this, we will delete the oldest table file

      Default: 1GB

      Returns:
      max table file size in bytes

    • setAllowCompaction

      public CompactionOptionsFIFO setAllowCompaction(boolean allowCompaction)
      If true, try to do compaction to compact smaller files into larger ones. Minimum files to compact follows options.level0_file_num_compaction_trigger and compaction won't trigger if average compact bytes per del file is larger than options.write_buffer_size. This is to protect large files from being compacted again.

      Default: false

      Parameters:
      allowCompaction - true to allow intra-L0 compaction
      Returns:
      the reference to the current options.

    • allowCompaction

      public boolean allowCompaction()
      Check if intra-L0 compaction is enabled. When enabled, we try to compact smaller files into larger ones.

      See setAllowCompaction(boolean).

      Default: false

      Returns:
      true if intra-L0 compaction is enabled, false otherwise.

    • disposeInternal

      protected final void disposeInternal(long handle)
