Ryan Blue commented on HADOOP-13126:
------------------------------------
The results above show the comparison with Snappy. The file is less than half
the size and compression took about the same amount of time. Comparing to LZ4
would be interesting. It isn't supported by Parquet so it's a bit harder for me
to drop into my test case.

> I've been testing [Brotli|https://github.com/google/brotli/], a new
> compression library based on LZ77 from Google. Google's [brotli
> benchmarks|https://cran.r-project.org/web/packages/brotli/vignettes/brotli-2015-09-22.pdf]
> look really good and we're also seeing a significant improvement in
> compression size, compression speed, or both.

> Brotli, at quality 1, is as fast as snappy and ends up smaller than gzip-9.
> Another test resulted in a slightly larger Brotli file than gzip produced,
> but Brotli was 4x faster. I'd like to get this compression codec into Hadoop.
