Apache NiFi should be configured for secure flow governance, repository performance, and predictable cluster behavior.
Important files:
conf/nifi.propertiesconf/authorizers.xmlconf/login-identity-providers.xml
Example settings (nifi.properties):
nifi.web.https.host=nifi.example.com
nifi.web.https.port=8443
nifi.cluster.is.node=true
nifi.zookeeper.connect.string=zk1:2181,zk2:2181,zk3:2181
nifi.security.user.login.identity.provider=ldap-provider
¶ Flow and policy controls
- Enforce least-privilege policies per process group.
- Version-control flows via NiFi Registry.
- Disable anonymous access and require authenticated users.
- Place content/provenance repositories on fast dedicated disks.
- Size JVM and repository storage for peak data rates.
- Set provenance retention by compliance needs.
¶ Backup and recovery
Back up:
- flow definitions and registry metadata
- NiFi configuration and security material
- repositories as required by your recovery target
Recovery test:
- Restore config and flow state.
- Validate cluster node join.
- Run representative dataflow end-to-end.
- Queue backpressure monitored.
- JVM and disk I/O monitored.
- TLS/keystore lifecycle monitored.
- Recovery drills documented.
