Dynamic data compression selection
First Claim
1. A method for data compression, the method comprising:
- receiving uncompressed source data at a data compression system from a data storage device, the uncompressed source data comprising a set of data chunks; and
streaming source data to a data target by, for each data chunk of at least some of the set of data chunks;
identifying a compression algorithm to use to compress the data chunk based on at least one performance factor, the compression algorithm being of a plurality of compression algorithms;
compressing the data chunk using the compression algorithm, wherein different compression algorithms are used to compress at least two of the set of data chunks; and
routing the compressed data chunk to the data target.

Abstract
Aspects of dynamic data compression selection are presented. In an example method, as uncompressed data chunks of a data stream are compressed, at least one performance factor affecting selection of one of multiple compression algorithms for the uncompressed data chunks of the data stream may be determined. Each of the multiple compression algorithms may facilitate a different expected compression ratio. One of the multiple compression algorithms may be selected separately for each uncompressed data chunk of the data stream based on the at least one performance factor. Each uncompressed data chunk may be compressed using the selected one of the multiple compression algorithms for the uncompressed data chunk.
