Configuring Flow Management clusters to hot load custom NARs
Hot loading custom NARs allows you to store NiFi custom processor NAR files in an external folder and load them dynamically from that location for use on the NiFi canvas. This makes it easy to add or update custom processors without having to restart your Flow Management cluster.
- You can configure NiFi to hot load custom NARs in all supported cloud providers.
- You can only access resources in the object store of the cloud provider in which your environment is running. But you can have a development and a production environment, for example, and configure both environments to access the same location to hot load custom NARs
-
It is possible to define multiple locations if desired by repeating the configuration properties with a different “[**custom-name**]” for each location. But all locations should be in the object store of the underlying cloud provider of where the NiFi cluster is located.
-
NiFi polls for new NARs in the configured location(s) every 5 minutes.
You can now drag a new processor onto NiFi canvas and search for your custom processor.
