WebApr 11, 2024 · Our benchmarks thus far have shown promising results, with compression ratio improvements ranging from 1.5x to 5x, depending on the data type (metrics, logs, traces), distribution, and compression algorithm. The approaches presented for addressing these challenges may be applicable to other Arrow domains as well. WebLossless image compression. Images are all around us, from application icons to animated GIFs to photos. Image files can take up a lot of space, so computers employ a range of algorithms to compress image files. For the simplest of images, computers can use a compression algorithm called run-length encoding (RLE).
