Java support for Snappy #15

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I'd love to see a JNI wrapper and/or a pure Java implementation of the codec.

I presume Google had the same desire internally.  The best choice externally 
may be different, but could you provide insight into which of pure 
java/jni/something else was used inside Google?

I'm sorry, I can't say much about what we do internally.

Same here — I'd have a good use for snappy in a Clojure application, but for 
that I need it to exist in the Java world. Doesn't have to be pure Java, 
JNI/JNA is fine.

A maven-distributed library would be ideal.

Hi all,

I am not sure how snappy is used with Java inside the Google, but
I started to develop a java-port of snappy, snappy-java, which uses JNI-based 
implementation to access natively compiled snappy. 
http://code.google.com/p/snappy-java

I confirmed that snappy can be used fine from Java. 
I would like to hear your advice to improve the snappy-java API to 
compress/decompress the data.

Hi,

As there now is a third-party JNI wrapper around Snappy, and people seem happy 
about it, the need for something in the Snappy distribution itself seems rather 
low. Thus, I'm closing this. Thanks for making this available!

Just wanted to add that I've implemented a pure Java version of Snappy. The 
compressor is not yet the fastest, but achieves mostly better result than the 
original implementation. The decompressor is reasonable fast.

You can find the implementation here on Google Code in the jsnappy project:

Nice. Would you like me to add that to the web page along with the other ports?

Do you have any benchmarks comparing this to the JNI version?

Yes, please link it everywhere you see it fit. 

I haven't compared it to the JNI version myself, but Chris Burroughs is already 
working on adding it to his JVM compressor benchmark suite. I hope that at 
least the decompressor is not far behind.
