Snappy is a compression/decompression library. Use the snappy.uncompress method to decompress Snappy-compressed files.
Snappy compression tool install#
Download and install the Snappy library for C++ from Snappy. This supports several file formats framing-format, old framing-format, hadoop-snappy format, raw format and obsolete three formats used by snzip, snappy-java and snappy-in-java before official framing-format was defined. The decompression tools include the Snappy library for C++, Snappy library for Java, Snappy library for Python, and Linux-based Snappy tool. Input file name without the `.snappy' suffix. Snzip is one of command line tools using snappy. `.snappy', the default output file name is the Omitted and the input file name ends with Run snappy without any arguments to check the usage description: $ snappy Decoding is compatible with Snappy compressed content, but content compressed with S2 cannot be decompressed by Snappy. usr/lib/jvm/jdk1.7.0_25/jre/lib/amd64/server/libjvm.so.Ĭheckout snappy-utils: $ git clone $SNAPPY_UTILS_HOMEĬopy the hadoop-snappy native library files to $SNAPPY_UTILS_HOME/lib: $ cp -r $HADOOP_SNAPPY_HOME/target/hadoop-snappy-0.0.1-SNAPSHOT-tar/hadoop-snappy-0.0.1-SNAPSHOT/lib/* $SNAPPY_UTILS_HOME/libĬreate a symbolic link to $SNAPPY_UTILS_HOME/bin/snappy under one of your $PATH directory: $ sudo ln -sf $SNAPPY_UTILS_HOME/bin/snappy /usr/bin S2 is aimed for high throughput, which is why it features concurrent compression for bigger payloads.
Snappy compression tool software#
The Arm software team has optimized both algorithms for high performance on Arm server platforms based on Arm Neoverse cores. If youre the guy developing software that could benefit from wire-speed compression, you should use LZ4. It is very popular in database and analytics applications. In our testing, we found Snappy to be faster and required fewer system resources than alternatives.
It is free: Google licensed under a BSD-type license. Usually, you may find libjvm.so in some subdirectory under $JAVA_HOME/jre/lib/, e.g. Snappy was developed as open-source algorithm by Google, and aims to optimize compression speed with reasonable compression ratios. Google says that Snappy has the following benefits: It is fast: It can compress data about 250 MB/sec (or higher) It is stable: It has handled petabytes of data Google. If Maven complains about -ljvm while building the native hadoop-snappy library, create a symbolic link to your libjvm.so under /usr/lib.
