> {{MeteredKeyValueStore}} passes the name of the changelog topic of the state store to the state store serdes. Currently, it always passes {{<application ID>-<store name>-changelog}} as the changelog topic name. However, for optimized source tables the changelog topic is the source topic. 
> Most serdes do not use the topic name passed to them. However, if the serdes actually use the topic name for (de)serialization, e.g., when Kafka Streams is used with Confluent's Schema Registry, a {{org.apache.kafka.common.errors.SerializationException}} is thrown.
