Bundle Persistence Providers

The bundle persistence provider stores the content of extension bundles saved to the registry. NiFi Registry provides FileSystemBundlePersistenceProvider and S3BundlePersistenceProvider.

The XML configuration file looks like below. It has a extensionBundlePersistenceProvider element in which the qualified class name of a persistence provider implementation and its configuration properties are defined. See following sections for available configurations for each provider.

Example extension bundle persistence provider in providers.xml

    <property name="property-1">property-value-1</property>
    <property name="property-2">property-value-2</property>
    <property name="property-n">property-value-n</property>
