             Summary: Introduce an Olingo4 results-already-seen property to 
filter old results
                 Key: CAMEL-13082
                 URL: https://issues.apache.org/jira/browse/CAMEL-13082
             Project: Camel
          Issue Type: New Feature
          Components: camel-olingo4
    Affects Versions: 2.23.0, 2.21.0
            Reporter: Paul Richardson


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.
