Describes options for how the compression algorithm is executed. Different strategies work better on different sorts of data. The strategy parameter can affect the compression ratio and the speed of compression but not the correctness of the compresssion.

The default strategy is probably the best for normal data.
The Filtered strategy is intended to be used most effectively with data produced by a
filter or predictor. By this definition, filtered data consists mostly of small
values with a somewhat random distribution. In this case, the compression algorithm
is tuned to compress them better. The effect of Filtered is to force more Huffman
coding and less string matching; it is a half-step between Default and HuffmanOnly.
Using HuffmanOnly will force the compressor to do Huffman encoding only, with no
