![]() 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. It does not aim for maximum compression, or compatibility with any other compression library instead, it aims for very high speeds and reasonable compression. snappy 1.1.8 3.el8 i686 38 k snappy-1.1. baseos Fast compression and decompression library https BSD Snappy is a compression/decompression library. Snappy is a compression/decompression library. In this tutorial we learn how to install snappy on CentOS 8. Do not store plain text files in Snappy compressed form, instead use a container like SequenceFile.Snappy is Fast compression and decompression library Fast compression and decompression library Introduction Plain text files: Like Gzip, Snappy is not splittable. Permanent Storage: Snappy compression is not efficient space-wise and it is expensive to store data on HDFS (3-way replication) Please do make sure these intermediate files are cleaned up soon enough so we don’t have disk space issues on the cluster. Temporary Intermediate files (not available currently as of Pig 0.9.2, applicable only to native Map Reduce) : If you have a series of MR jobs chained together, Snappy compression is a good way to store the intermediate files. If you try to run Ceph with snappy 1.1.9 installed, ceph status will show HEALTHWARN, and tell you that your OSDs have broken BlueStore compression. Map output: Snappy works great if you have large amounts of data flowing from Mappers to the Reducers (you might not see a significant difference if data volume between Map and Reduce is low)
