I didn't make an assertion *about* Accumulo, what I said exactly was:
"that Accumulo may or may not suffer from "bifurcation" is
debatable"
I assert there are two sides to that argument (I've heard them both),
merely to suggest that Sean's concerns should not be dismissed as they
were.

>>>>>>> control, feedback, and monitoring of data flows

>>>>>>> on-the-fly data flow generation, modification, and observation.
>>>>>>>
>>>>>>> == Rationale ==
>>>>>>> NiFi provides a reliable, scalable, manageable and accountable
>>>>>>> platform for developers and technical staff to create and evolve

>>>>>>> including large-scale enterprise integration, interaction with cloud
>>>>>>> services and frameworks, business to business, intra-departmental,
>>>>>>>
>>>>>> and
>>>

>>>>>>> Foundation (ASF) family as it depends on numerous ASF projects and
>>>>>>> integrates with several others. We also anticipate developing
>>>>>>> extensions for several other ASF projects such as Cassandra, Kafka,
>>>>>>> and Storm in the near future.
