DYNAMIC DATA COMPRESSION SELECTION

摘要

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.

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 of data comprising data chunks of a data stream; monitoring, utilizing a hardware processor of the data compression system, at least one performance factor of the data compression system; selecting a first compression algorithm from a plurality of compression algorithms based on the monitored at least one performance factor of the data compression system; and compressing a first uncompressed data chunk of the data stream using the selected first compression algorithm.
