In Transformation Hub Kafka Manager, users will see different offset values between CEF (such as Logger) topics and binary (ESM) topics. In CEF topics, the offset value can generally be associated with number of events that passed through the topic. Each message in a CEF topic is an individual event. However, that same association cannot be made for the ESM topic, as several events are batched into each message.
