Connections

Q: If I have FlowFiles stuck in my queue, how can I clear them out?

  • A: If you are testing a flow and do not care about what happens to the test data that is stuck in a connection queue, you can temporarily set the FlowFile Expiration to something like 1 sec so that the FlowFiles currently in the queue will expire. Then, you can reset it to 0 sec (which means never expire). Note that you must stop both processors on either side of a connection before you can edit the settings.

Clustering

Q: I am evaluating NiFi for a large project to see if NiFi would fit as the main data collector. The project I am working on would require retrieving several hundreds of millions of files per day (hundreds of TB per day) so my first question is how to achieve distribution/clustering with NiFi, if that's possible.

  • A: The NiFi Administrator Guide includes a quick explanation of our clustering capabilities and example configurations. This would be a great place to start and become familiar with NiFi clustering.
