Allen Wittenauer commented on HADOOP-7206: ------------------------------------------ With the current state of trunk, native compression only works on Linux anyway without reworking the entire libhadoop structure. See HADOOP-7405. > Integrate Snappy compression > ---------------------------- > > Key: HADOOP-7206 > URL: https://issues.apache.org/jira/browse/HADOOP-7206 > Project: Hadoop Common > Issue Type: New Feature > Affects Versions: 0.21.0 > Reporter: Eli Collins > Assignee: T Jake Luciani > Fix For: 0.23.0 > > Attachments: HADOOP-7206-002.patch, HADOOP-7206.patch, > v2-HADOOP-7206-snappy-codec-using-snappy-java.txt, > v3-HADOOP-7206-snappy-codec-using-snappy-java.txt, > v4-HADOOP-7206-snappy-codec-using-snappy-java.txt, > v5-HADOOP-7206-snappy-codec-using-snappy-java.txt > > > Google release Zippy as an open source (APLv2) project called Snappy > (http://code.google.com/p/snappy). This tracks integrating it into Hadoop. > {quote} > Snappy is a compression/decompression library. 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. On a single core of a Core i7 processor in 64-bit mode, Snappy > compresses at about 250 MB/sec or more and decompresses at about 500 MB/sec > or more. > {quote} -- This message is automatically generated by JIRA.
