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