@krishna123 @jameswookyz @rafy NiFi processor are configured with a Run Schedule, by default processors are configured with a Run Schedule of 0 secs. This tells NiFi core to schedule this processor to execute as often as possible. The Scheduling part of the processor handles checking if any of the inbound connections to the processor with queued data or last execution resulted in data. If there is no inbound queued FlowFiles, the NiFi controller will yield the processor scheduling. This yielding is designed to prevent the processor from just constantly trying to schedule when there is no work to do. If there is work to do, the processor will get scheduled to execute. The scheduling typically consumes microseconds of CPU time. And the built-in yielding prevents excessive cpu usage when no work exists to execute upon. Adjusting the run schedule does not change behavior of yielding, but when flow is constant for periods of time, changing the run schedule alters the throughput performance. Hope this clarifies things.

I dont think you can use PutSQL for this. Try ExecuteSQL or you might have to use ExecuteScript processor as other posts suggest: https://community.cloudera.com/t5/Support-Questions/Does-ExecuteSQL-processor-allow-to-execute-stored-procedure/m-p/158922 https://stackoverflow.com/questions/72348844/get-output-of-stored-procedure-using-putsql-in-nifi If that helps please accept solution. Thanks

@udayAle @ep_gunner When NiFi is brought down, the current state (stopped, started, enabled, disabled) of all components is retained and on startup that same state is set on the components. Only time this is not true is when the property "nifi.flowcontroller.autoResumeState" is set to false in the nifi.properties file. When set to false a restart of NiFi would result in all components in a stopped state. In a production environment, this property should be set to true. Perhaps you can share more details on the maintenance process you are using as I am not clear on how your maintenance is impacting the last known state of some components.

Thank you all. I eventually evaluated the json path to extract the url. My mind was astray as i was using complex solution to a simple problem.

@rafy The ERROR shared seems unrelated to the action of emptying a connection queue. Are you trying to delete a connection or empty a connection queue? Can you share screenshots of the actions being performed? Can you collect the full stack trace produced in the nifi-app.log when you perform the action? Thank you, Matt

Hi All, Please can you kindly look into this issue i have with QueryNiFiReportingTask processor. PLATFORM: - WSL2 with Ubuntu 20.04 as OS - jdk-11.0.15 - NIFI 1.17.0 SCENERIO: I am trying to monitor all processors so as to know which one has stopped & sending notification through email sink. I configured gmail email sender appropriately. ISSUES: No email received & there was no error on the bulleting indicating failure. NOTE: I changed smtp to different ones but got errors.
