CompressionMode()
Sole constructor.
Declaration
protected CompressionMode()Fields
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.
Declaration
public static readonly CompressionMode FASTField Value
| Type | Description |
|---|---|
| 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.
Declaration
public static readonly CompressionMode FAST_DECOMPRESSIONField Value
| Type | Description |
|---|---|
| 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.
Declaration
public static readonly CompressionMode HIGH_COMPRESSIONField Value
| Type | Description |
