* Pass a processor to region to process multiple rows atomically.

* the Coprocessor endpoint together.
*
* See {@code TestRowProcessorEndpoint} for example.
*
* The request contains information for constructing processor
* (see {@link #constructRowProcessorFromRequest}. The processor object defines
* the read-modify-write procedure.
