James Taylor resolved PHOENIX-1509.
-----------------------------------
       Resolution: Fixed
    Fix Version/s: 4.3

Thanks for investigating this, [~mujtaba]. Looks like PREFIX versus FAST_DIFF 
is kind of a wash, so we'll leave as-is.

> Investigate changing default encoding to PREFIX_encoding instead of FAST_DIFF

> [~lhofhansl] mentioned to me a performance evaluation that found 
> PREFIX_ENCODING to be much less CPU intensive than FAST_DIFF (which is the 
> default for Phoenix tables). We should perf test this ourselves and change 
> the default if the results look good.
