The LZW algorithm is a very common compression technique. This algorithm is typically used in GIF and optionally in PDF and TIFF. Unix’s ‘compress’ command, among other uses. It is lossless, meaning no data is lost when compressing. The algorithm is simple to implement and has the potential for very high throughput in hardware
LZO or other algorithms with such tricks (e.g., by using a tiny dictionary of frequently occurring patterns). However, since the focus of this paper is not compression algorithms per se, we do not explore this direction here. TablesIandIIshow compression ratio and compression rate for several workloads using straight LZO-1X algorithm. After twenty years, a vulnerability in Lempel-Ziv-Oberhumer (LZO), an extremely efficient compression algorithm, has finally been patched. The flaw, a subtle integer overflow, existed for as long The LZO algorithm was created in 1994 by Markus Oberhumer, whose core open source implementation has been rewritten by numerous companies. LZO has been used for compression and decompression in various software applications, including OpenVPN , MPlayer2, Libav, FFmpeg, the Linux kernel, Android, iOS and even in the embedded systems that power LZO encoding provides a very high compression ratio with good performance. LZO encoding works especially well for CHAR and VARCHAR columns that store very long character strings, especially free form text, such as product descriptions, user comments, or JSON strings. Columns that are defined as CHAR or VARCHAR data types are assigned LZO compression. The following table identifies the supported compression encodings and the data types that support the encoding.
[MS-XCA]: Xpress Compression Algorithm. 5/8/2020; 4 minutes to read; In this article. Specifies the three variants of the Xpress Compression Algorithm: LZ77+Huffman, Plain LZ77, LZNT1, and their respective decompression algorithms. This algorithm efficiently compresses data that contains repeated byte sequences.
The algorithm gives a slightly worse compression ratio than the LZO algorithm – which in turn is worse than algorithms like DEFLATE. However, compression speeds are similar to LZO and several times faster than DEFLATE, while decompression speeds can be significantly higher than LZO.  LZO 2.10 has been released; a small update that fixes various build issues. Key Facts. LZO is a portable lossless data compression library written in ANSI C. Offers pretty fast compression and *extremely* fast decompression. One of the fastest compression and decompression algorithms around.
LZO: Similar to Snappy, LZO (short for Lempel-Ziv-Oberhumer, the trio of computer scientists who came up with the algorithm) provides modest compression ratios, but fast compression and decompression speeds. LZO is licensed under the GNU Public License (GPL). LZO supports splittable compression, which enables the parallel processing of
LZ4 is lossless compression algorithm, providing compression speed > 500 MB/s per core (>0.15 Bytes/cycle). It features an extremely fast decoder, with speed in multiple GB/s per core (~1 Byte/cycle). A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio. The LZW algorithm is a very common compression technique. This algorithm is typically used in GIF and optionally in PDF and TIFF. Unix’s ‘compress’ command, among other uses. It is lossless, meaning no data is lost when compressing. The algorithm is simple to implement and has the potential for very high throughput in hardware Pages are compressed using the bundled zlib compression algorithm. This is the default value in MariaDB 10.2.4 and later, and MariaDB 10.1.22 and later. lz4: Pages are compressed using the lz4 compression algorithm. lzo: Pages are compressed using the lzo compression algorithm. lzma: Pages are compressed using the lzma compression algorithm. bzip2 Jul 26, 2019 · Btrfs supports transparent file compression. There are three algorithms available: ZLIB, LZO and ZSTD(since v4.14). Basically, compression is on a file by file basis. You can have a single btrfs mount point that has some files that are uncompressed, some that are compressed with LZO, some with ZLIB, for instance (though you may not want it that way, it is supported).
