Technology for adaptive compression is described (the technology). The technology may identify two or more partitions of a data stream; optionally pre-process data in each partition; create one or more evaluation functions to evaluate a suitability for compression of the data in each partition using a set of potential compression methods; process the created one or more evaluation functions; choose a subset of the set of potential compression methods for each segment at least partly by analyzing the evaluation functions; select a compression method for each segment based on a compression ratio of compressing the sequence of used compression methods and a compression rate of the data; compress the data in each partition using the selected compression method for the partition; compress a subsequence that indicates which compression method is used for each segment. |
