Data Compression with the Snappy Frame Format. Fortunately, Google has also published a specification for a variation on the Snappy format called Snappy framing format. This format modifies the Snappy compression algorithm to compress a file incrementally, such that the compressed result is composed of independent, compressed chunks or
Snap (package manager) - Wikipedia Snap is a software deployment and package management system developed by Canonical for the Linux operating system. The packages, called snaps, and the tool for using them, snapd, work across a range of Linux distributions allowing distribution-agnostic upstream software packaging. Snap was originally designed for Ubuntu Touch. New Compression Options in MongoDB 3.0 | MongoDB Blog Apr 30, 2015 Is Snappy compressed Parquet file splittable?

ORCFile in HDP 2: Better Compression, Better Performance
Mar 05, 2018 · Graphs below include switch from no compression (before 2/9) to Snappy (2/9 to 2/17) to Zstandard (after 2/17): The decrease in size was 4.5x compared to no compression at all. On next generation hardware with 2.4x more storage and 2.5x higher network throughput we suddenly made our bottleneck more than 10x wider and shifted it from storage and compression {‘snappy’, ‘gzip’, ‘brotli’, None}, default ‘snappy’ Name of the compression to use. Use None for no compression. index bool, default None. If True, include the dataframe’s index(es) in the file output. If False, they will not be written to the file. If None, similar to True the dataframe’s index(es) will be Data Compression with the Snappy Frame Format. Fortunately, Google has also published a specification for a variation on the Snappy format called Snappy framing format. This format modifies the Snappy compression algorithm to compress a file incrementally, such that the compressed result is composed of independent, compressed chunks or
Snappy compression for Windows
However, it is only a wrapper around the snappy implementation in c that should be installed in your computer, this issue has been addressed in this answer about installing snappy-c. Assuming you have a DEB-based system, such as ubuntu, you can get it with: sudo apt-get install libsnappy-dev python3 -m pip install --user python-snappy It does not aim for maximum compression, or compatibility with any other compression library; instead, it aims for very high speeds and reasonable compression. For instance, compared to the fastest mode of zlib, Snappy is an order of magnitude faster for most inputs, but the resulting compressed files are anywhere from 20% to 100% bigger. Snappy may refer to: . Snappy (compression), a compression and decompression library Snappy (package manager), a software tool for the Ubuntu operating system Snappy Dance Theater, a dance company in Cambridge, Massachusetts Homebrew’s package index. snappy. Compression/decompression library aiming for high speed. https://google.github.io/snappy/ Jan 04, 2017 · Starting with Hive 0.13, the ‘PARQUET.COMPRESS’=’SNAPPY’ table property can be set to enable SNAPPY compression. You can alternatively set parquet.compression=SNAPPY in the “Custom hive-site settings” section in Ambari for either IOP or HDP which will ensure that Hive always compresses any Parquet file it produces. InnoDB page compression can encounter compression failures. InnoDB page compression's failure threshold can be configured. If InnoDB encounters more compression failures than the failure threshold, then it pads pages with zeroed out bytes before attempting to compress them as a way to reduce failures.
