object Metadata

Messages for Kafka metadata fetching via KafkaConsumerActor.

NOTE: Processing of these requests blocks the actor loop. The KafkaConsumerActor is configured to run on its own dispatcher, so just as the other remote calls to Kafka, the blocking happens within a designated thread pool. However, calling these during consuming might affect performance and even cause timeouts in extreme cases.
