Property

Description

nifi.provenance.repository.debug.frequency

Controls the number of events processed between DEBUG statements documenting the performance metrics of the repository. This value is only used when DEBUG level statements are enabled in the log configuration.

nifi.provenance.repository.encryption.key.provider.implementation

This is the fully-qualified class name of the key provider. A key provider is the datastore interface for accessing the encryption key to protect the provenance events. There are currently two implementations - StaticKeyProvider which reads a key directly from nifi.properties, and FileBasedKeyProvider which reads n many keys from an encrypted file. The interface is extensible, and HSM-backed or other providers are expected in the future.

nifi.provenance.repository.encryption.key.provider.location

The path to the key definition resource (empty for StaticKeyProvider, ./keys.nkp or similar path for FileBasedKeyProvider). For future providers like an HSM, this may be a connection string or URL.

nifi.provenance.repository.encryption.key.id

The active key ID to use for encryption (e.g. Key1).

nifi.provenance.repository.encryption.key

The key to use for StaticKeyProvider. The key format is hex-encoded (0123456789ABCDEFFEDCBA98765432100123456789ABCDEFFEDCBA9876543210) but can also be encrypted using the ./encrypt-config.sh tool in NiFi Toolkit.

nifi.provenance.repository.encryption.key.id.*

Allows for additional keys to be specified for the StaticKeyProvider. For example, the line nifi.provenance.repository.encryption.key.id.Key2=012...210 would provide an available key Key2.
