Zstandard is a fast compression algorithm, providing high compression ratios. It also offers a special mode for small data, called dictionary compression. The reference library offers a very wide range of speed / compression trade-off, and is backed by an extremely fast decoder (see benchmarks below). Zstandard library is provided as open source software using a BSD license. Its format is stable a
Firefox's Optimized Zip Format: Reading Zip Files Really Quickly This post is about minimizing amount of disk IO and CPU overhead when reading Zip files. I recently saw an article about a new format that was faster than zip. This is quite surprising as to my mind, zip is one of the most flexible and low-overhead formats Iâve encountered. Some googling showed me that over past 11 years people have

For compression, we put three lossless and widely accepted libraries to the test: Snappy zlib Bzip2 (BZ2) Snappy aims to provide high speeds and reasonable compression. BZ2 trades speed for better compression, and zlib falls somewhere between them. Testing Our goal was to find the combination of encoding protocol and compression algorithm with the most compact result at the highest speed. We teste
Generally, data compression techniques are used to conserve space and network bandwidth. Widely used compression techniques include Gzip, bzip2, lzop, and 7-Zip. According to performance benchmarks, lzop is one of the fastest compression algorithms, while bzip2 has a high compression ratio but is very slow. Gzip offers the lowest level of compression. Gzip is based on the DEFLATE algorithm, which

The latest news from Google on open source releases, major projects, events, and student outreach programs. At Google, we think that internet usersâ time is valuable, and that they shouldnât have to wait long for a web page to load. Because fast is better than slow, two years ago we published the Zopfli compression algorithm. This received such positive feedback in the industry that it has been in
XZ Utils are a complete C99 implementation of the .xz file format. XZ Utils were originally written for POSIX systems but have been ported to a few non-POSIX systems as well. The core of the XZ Utils compression code is based on LZMA SDK but it has been modified significantly to be suitable for XZ Utils. liblzma is a compression library with an API similar to that of zlib. xz is a command line too

We've realized a bit too late that archiving our files in GZip format for Hadoop processing isn't such a great idea. GZip isn't splittable, and for reference, here are the problems which I won't repeat: Very basic question about Hadoop and compressed input files Hadoop gzip compressed files Hadoop gzip input file using only one mapper Why can't hadoop split up a large text file and then compress t

Kari shared the stories and strategies that inform her leadership style (like GSD or âgetting stuff doneâ), what it means to trust your instinct, and the advice she gives to young women embarking on a career in technology and to women furth
