Scott Carey commented on HADOOP-7206:
-------------------------------------
Would it be reasonable to split snappy-java up into multiple maven modules, so
that users can choose which parts they want? Perhaps they want the Java
portions, but none of the JNI, or want the JNI wrapper but not the
implementation, etc. A snappy-java could still be built with all artifacts
bundled, but a la carte could also be chosen without a custom build of
snappy-java.
I think it is best for users if as many use cases as possible were handled in
one central library that could be shared by multiple projects. Any work done
for Hadoop is likely to be repeated elsewhere.

> Google release Zippy as an open source (APLv2) project called Snappy
> (http://code.google.com/p/snappy). This tracks integrating it into Hadoop.

> 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.
