Josh Elser commented on PHOENIX-3218:
-------------------------------------

bq. Is this doc the right place to say this? Seems like it would be kind of 
hidden here. The Grammar page mentions commits kind of off-handedly, as does 
the Atomic Upsert page.

Ignoring the transaction feature (as that is "standard"), when I first started 
poking at Phoenix, I was rather confused at the "overloading" of the 
{{commit()}} method to control shipping of edits to HBase. IMO, since you are 
bringing how up batching works, I figured it would be a good idea to at least 
nod to this point.

(and even though you didn't explicitly ask me about these..)

bq. Similar question—what's a more reliable way to determine cache update 
frequency?

I think 15mins is a fine value -- my suggestion was just to use stronger 
language in stating it.
