Choosing a Compression Setting

Lists the compression algorithms supported by data-fabric.

Data Fabric supports three different compression algorithms:

• lz4 (default)
• lzf
• zlib

Compression algorithms can be evaluated for compression ratio (higher compression means less disk space used), compression speed and decompression speed. The following table gives a comparison for the three supported algorithms. The data is based on a single-thread, Core 2 Duo at 3 GHz.

Note that compression speed depends on various factors including:

• block size (the smaller the block size, the faster the compression speed)
• single-thread vs. multi-thread system
• single-core vs. multi-core system
• the type of codec used
