Hi, I have these questions related to the way of working of GetMongo and Nifi queues:
a. do GetMongo processor writes the results into the Nifi queue as a set of records (array of documents) or simply writes each record (document) one by one?
b. do GetMongo processor writes immediately each batch of returned records into the Nifi queue or is waiting to gather all the data for the query and then writes?
c. when GetMongo processor writes the results in the Nifi queue is it also blocking the queue for reads till finishing the writing of all records? I mean depending on the answer a MergeContent processor might see all the query returned records or only part of them depending on the moment of reading.
