    In order to avoid making existing processors invalid or change the way that 
they behave, we should add a default value of "true" to this property. Then the 
user is still able to disable the pretty-printing, but those who are satisfied 
with the current behavior are not affected.

> Pretty printed JSON can explode the size of a MongoDB result set, 
> particularly on large queries. Right now, pretty printing is done all the 
> time and isn't configurable. It should be configurable.
