Hi Yan, We can get more into details and particulars if needed, but have you experimented with expression language? I could see a Cron driven approach which covers your periodic efforts that feeds some number of ExecuteSQL processors (perhaps one for each database you are communicating with) each having a table. This would certainly cut down on the need for the 30k processors on a one-to-one basis with a given processor.
In terms of monitoring the dataflows, could you describe what else you are searching for beyond the graph view? NiFi tries to provide context for the flow of data but is not trying to be a sole monitoring, we can give information on a processor basis, but do not delve into specifics. There is a summary view for the overall flow where you can monitor stats about the components and connections in the system. We support interoperation with monitoring systems via push (ReportingTask) and pull (REST API [2]) semantics. Any other details beyond your list of how this all interoperates might shed some more light on what you are trying to accomplish. It seems like NiFi should be able to help with this. With some additional information we may be able to provide further guidance or at least get some insights on use cases we could look to improve upon and extend NiFi to support. Thanks!
