Data compression is the process of reducing the size of a file using some compression algorithm. Image compression can be lossless or lossy. Deflate is the fastest algorithm in terms of compression and decompression speed, but provides low compression ratio. Since today the size of that compressed data on the hard drive does not really matter (talking about PCs here, on embedded this is a different story) it makes sense to use the fastest algorithm. Mar 14, 2024 · TimescaleDB deploys different compression algorithms, depending on the data type: Delta-of-delta + Simple-8b with run-length encoding compression for integers, timestamps, and other integer-like types; XOR-based compression for floats; Whole-row dictionary compression for columns with a few repeating values (plus LZ compression on top) Every compression algorithm is a tradeoff between the size of the compressed data blob and its speed. ZIPX (WinZip), ZPAQ (PeaZip), and 7Z (7-Zip, PeaZip) compression algorithms are comparable for speed, and significantly slower than RAR and ARC, with Bandizip 7Z compression being slower that other 7Z implementations and the second slowest performance of the benchmark before ZPAQ ultra level. At minimum and default compression level Deflate algorithm is used, at maximum compression level WinZip tries to determine the most fit algorithm from supported ones, including BZip2, LZMA and PPMd. Brotli is slower at compression, but ~5x faster at decompression. Basically, this class of algorithms is based on the fact that in most cases it is sufficient to encode only those residues, resulting from the difference between the predicted value and the actual value, which fall inside a relatively small range [− R, R] and to transmit the values outside this range (i.
