16 +{{info}}Given that the implementation of the prerequisites can differ, the results of what you see can also differ. We use example data that is part of our Sales Demo model to feed the Vehicle Event topic. An event processor subsequently determines whether a vehicle alert needs to be generated based on the type of event. This accounts for the difference in partition size between both topics. An event processor is a consumer group, and due to the high volume of messages placed on the Vehicle Event topic, we see that a consumer lag is reported.{{/info}}
