Dynamic data compression selection

A computer-program product tangibly embodied in a non-transitory machine-readable storage medium, including instructions configured to cause one or more data processors to perform actions including:

• receiving a data stream at data-target system from a single data source;
• detecting each of a set of compressed data chunks within the data stream;
• and
• for each compressed data chunk of at least some of the set of compressed data chunks:
• identifying a compression algorithm was used to compress the compressed data chunk, wherein the compression algorithm identified to have been used to compress a first compressed data chunk of the at least some of the set of compressed data chunks is a first compression algorithm that differs from a second compression algorithm identified to have been used to compress a second compressed data chunk of the at least some of the set of compressed data chunks;
• selecting a decompression algorithm based on the identified compression algorithm;
• and
• decompressing the compressed data chunk using the decompression algorithm.

A system for data compression including:

• one or more data processors;
• and
• a non-transitory computer readable storage medium containing instructions which when executed on the one or more data processors, cause the one or more data processors to perform actions including:
• receiving a data stream at data-target system from a single data source;
• detecting each of a set of compressed data chunks within the data stream;
• and
• for each compressed data chunk of at least some of the set of compressed data chunks:
• identifying a compression algorithm was used to compress the compressed data chunk, wherein the compression algorithm identified to have been used to compress a first compressed data chunk of the at least some of the set of compressed data chunks is a first compression algorithm that differs from a second compression algorithm identified to have been used to compress a second compressed data chunk of the at least some of the set of compressed data chunks;
• selecting a decompression algorithm based on the identified compression algorithm;
• and
• decompressing the compressed data chunk using the decompression algorithm.
