Sumit Nigam commented on PHOENIX-3218:
--------------------------------------

Thank you for this good initiative. I have some queries/ suggestions:

In improving parallelization, you mentioned:
*Turn on stats, should improve it*
I thought stats are turned ON by default. Is that not correct?

Plus, I could not understand the following recommendation in the document:
*Configure stats to use small pipe size, creates even more stats*
Did you mean having lesser sized guideposts by reducing value of 
phoenix.stats.guidepost.width from default 100Mb?

Lastly, using the IncreasingToUpperBoundRegionSplitPolicy (default) causes 
first region split at 128Mb. Is phoenix.stats.guidepost.width (100M) a good 
value or should it ideally be reduced from beginning itself given it is almost 
same as region size?

We can also mention in the document that if we are reducing the size of the 
guideposts, then phoenix.query.queueSize may need increasing as more work will 
be queued thereafter.
