Hi Everyone I was wondering if it possible to run multiple NiFi Registry servers for high-availability purposes when using a remote database for metadata and flows/users & groups/polices and S3 for bundles?
I’m intending to deploy NiFi Registry on Kubernetes, and will be using a remote PostgreSQL instance for metadata, plus the DatabaseUserGroupProvider/DatabaseAccessPolicyProvider/DatabaseFlowPersistenceProvider and S3BundlePersistenceProvider. All configuration (nifii-registry.properties, authorisers.xml, etc) will be stored as ConfigMaps. Consequently, I shouldn’t need any persistent storage in my K8s pod, and am wondering if I can deploy as a ReplicaSet with > 1 replicas for HA purposes. Is having multiple NiFi Registry Servers untested/supported, or is it something people are commonly doing without any problems? Any pointers much appreciated Thanks Austin
