```
    Get the current persistence ids for a given entity type.
    The persistenceIds must start with the entity type followed by default separator ("|") from PersistenceId.
    
    Parameters:
    
    entityType - The entity type name.
    
    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.
    
    Returns:
    
    A source containing all the persistence ids, limited as specified.
