Abstract
One example method includes file specific compression selection. Compression metrics are generated for a chunk of a file using a reference compressor. Compression metrics for other compressors are determined from the metrics of the reference compressor. A compressor is then selected to compress the file.
Claims20
A method, comprising:
- receiving a file at a compression engine configured to select an optimal compressor from a set of compressors to compress the file;
- extracting a chunk from the file;
- compressing the chunk with a reference compressor included in the set of compressors;
- determining compression metrics for the reference compressor;
- determining compression metrics each of the compressors in the set of compressors based on the compression metrics of the reference compressor;
- determining a correction factor for each of the compressors in the set of compressors;
- determining estimated file metrics for each of the compressors based on the compression metrics and the correction factors;
- and
- selecting the optimal compressor for compressing the file based on the estimated file metrics.
