Subject Re: Decrease HTTP chattiness?

I am not familiar with the JDBC driver, but Phoenix uses Avatica[1] 
under the hood. The protobuf documentation does state that it's possible 
to control the number of rows returned in each response. See 
frame_max_size under the FetchRequest[2] message. This may be something 
that you can set in the JDBC driver.
