Amar Kamat updated MAPREDUCE-2542:
----------------------------------
Attachment: compression-ratio-dictsize-500-data-100mb-lzo.png
Attaching a plot of dictionary-word-size to compression ratio for a fixed
dictionary size of 500 words and fixed data size of 100mb. I will publish the
text version of the table too which can be used for compiling the compression
lookup table.

> MAPREDUCE-2408 adds compression emulation support in Gridmix. It supports the
> commonly used default codec (i.e Gzip). It seems that even LZO codec shows
> similar pattern w.r.t dictionary-word-size and compression-ratio. It would be
> nice to emulate LZO codec in Gridmix.
