Default: kSnappyCompression, which gives lightweight but fast
compression.
Typical speeds of kSnappyCompression on an Intel(R) Core(TM)2 2.4GHz:
~200-500MB/s compression
~400-800MB/s decompression
Note that these speeds are significantly faster than most
persistent storage speeds, and therefore it is typically never
worth switching to kNoCompression. Even if the input data is
incompressible, the kSnappyCompression implementation will
efficiently detect that and will switch to uncompressed mode.
Compress blocks using the specified compression algorithm. This parameter can be changed dynamically.
