```
Source<java.lang.String,NotUsed> currentPersistenceIds(scala.Option<java.lang.String> afterId,
                                                             long limit)
```
    Get the current persistence ids.
    Not all plugins may support in database paging, and may simply use drop/take Pekko streams operators to manipulate the result set according to the paging parameters.
    
    Parameters:
    
    afterId - The ID to start returning results from, or None 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.MaxValue to return all results. Must be greater than zero.
    
    Returns:
    
    A source containing all the persistence ids, limited as specified.
