Not all plugins may support in database paging, and may simply use drop/take Akka streams operators to manipulate the result set according to the paging parameters.
afterId- The ID to start returning results from, or empty to return all ids. This should be an id returned from a previous invocation of this command. Callers should not assume that ids are returned in sorted order.
limit- The maximum results to return. Use Long.MAX_VALUE to return all results. Must be greater than zero.
- A source containing all the persistence ids, limited as specified.
