4mc - Four More Compression About The 4MC (4 More Compression) is a library for hadoop providing a newsplittable compressed file format(4mc) which lets you leverage the power of LZ4 and ZSTD algorithms. It's been designed to add more features to existing big data solutions like HADOOP/El...
-z: enable compression with a specified algorithm (any/none/brotli/lz4/zstd) -Z: disable compression 不太理解这个compression with a specified algorithm是什么意思,是传输前压缩,传输后解压吗 一次压缩多少大小的内容呢,全部压缩完再传吗 我搜英文也搜不到相关的结果 从源码来看 涉及下面这几段代码 command...
(原创)zram算法比较以及zstd移植 zram类似压缩饼干,是将RAM中暂时不用的部分RAM使用压缩算法压缩后,在写会RAM中,以达到RAM释放的功能。zram是一个块驱动,源码在kernel根目录下的drivers/block/zram下,相关源码这里不做分析,这篇就简单做一下压缩算法性能的对比。这次主要对比的算法是lzo、lz4和自行移植的...

Support is also added in the command line utilitylz4, using the new command-D, implemented by@felixhandte. The behavior of this command is identical tozstd, should you be already familiar. lz4doesn't specify how to build a dictionary. All it says is that it can be any file up to 64 ...
Enabling Compression Level configuration of ZSTD and ZSTD (No Dict) #7555 Closed Contributor Author sarthakaggarwal97 commented Aug 14, 2023 I've performed some benchmarks with 8K and 16 Block sizes with LZ4 (default) compression codec with HTTP Logs Dataset. I've observing around 3% impro...
lz4liteprovides access to the extremely fast compression inlz4for performing in-memory compression. As of v0.2.0,lz4litecan now serialize and compress any R object understood bybase::serialize(). If the input is known to be an atomic, numeric vector, and you do not care about any attribute...
