final class Resource extends AnyRef

Some connectors might require an external resource that is used in the Source, Flow and/or Sink factories.

For example dynamodb connector needs a DynamoClient to create Sources and Flows. Another example is Google Pub Sub gRPC connector that uses Grpc Publishers and Subscribers to create Sources and Sinks. Another connector, Alpakka Kafka, uses an actor that can be shared across different streams.

If your connector uses such a resource and it is possible to reuse that resource across different Akka Stream operator factories, put that resource to a separate class like below.
