Class CompressionMode


  • public abstract class CompressionMode
    extends java.lang.Object
    A compression mode. Tells how much effort should be spent on compression and decompression of stored fields.
    • Field Detail

      • FAST

        public static final CompressionMode FAST
        A compression mode that trades compression ratio for speed. Although the compression ratio might remain high, compression and decompression are very fast. Use this mode with indices that have a high update rate but should be able to load documents from disk quickly.
      • HIGH_COMPRESSION

        public static final CompressionMode HIGH_COMPRESSION
        A compression mode that trades speed for compression ratio. Although compression and decompression might be slow, this compression mode should provide a good compression ratio. This mode might be interesting if/when your index size is much bigger than your OS cache.
      • FAST_DECOMPRESSION

        public static final CompressionMode FAST_DECOMPRESSION
        This compression mode is similar to FAST but it spends more time compressing in order to improve the compression ratio. This compression mode is best used with indices that have a low update rate but should be able to load documents from disk quickly.
