Subject Re: Controlling number of threads in distributed mode
Date Thu, 14 Feb 2019 02:52:02 GMT
Hi Joe,
Use case is I have to query HTTP request.  The HTTP  request  from  NIFI can only run 3 queries
at a time.

The queries to be executed are coming from Kafka topic and we have 6 node cluster.
Ideally would like to run the 3 http queries from 3 different nodes otherwise one of the node
(primary node) will be overloaded with data.
