> The current polling implementation of the olingo4 consumer is to extract
> results from the target OData service every n seconds, with the results of
> each polling being identical. In the same way as the twitter component it
> would be useful for the consumer to recognise individual results as 'already
> seen' and filter them out. This has the following advantages:
> * A set of polling results no longer contains the 'noise' of repeated
> results;
> * With the possibility of all results being filtered out since they've
> already been seen, it is possible for the polling to idle and await new data
> rather than constantly returning the same results repeatedly.
