Tim Broberg commented on HADOOP-7657:
-------------------------------------
I think I'm seeing ~5:1 compression ratios here, is that right?
Compression performance is generally highly sensitive to input data,
decompression even more so.
Is it at all typical to see 5:1 compression with live Hadoop data?
If not, is there an appropriate corpus of data that reflects normal usage?
> Add support for LZ4 compression

> Labels: compression

> According to several benchmark sites, LZ4 seems to overtake other fast
> compression algorithms, especially in the decompression speed area. The
> interface is also trivial to integrate
> (http://code.google.com/p/lz4/source/browse/trunk/lz4.h) and there is no
> license issue.
