S3BundlePersistenceProvider

The S3BundlePersistenceProvider stores the content of extension bundles in a AWS S3 bucket. The bucket is expected to already exist and be accessible to the credentials provided to the persistence providcer.

	Note
	This provider must be added to the classpath by specifying a custom extension directory in nifi-registry.properties, such as nifi.registry.extension.dir.aws=./ext/aws/lib, where ./ext/aws/ contains the contents of the extracted nifi-registry-aws-assembly-<version>-bin.zip.

The key of an extension bundle in the S3 bucket will be the following:

/{registry-bucket-id}/{group-id}/{artifact-id}/{version}/{artifact-id}-{version}.{extension}

If an optional Key Prefix is specified, then that prefix will be applied to the beginning of the above key.
