One proposal of this API is here - https://cwiki.apache.org/confluence/display/KAFKA/Kafka+replication+detailed+design+V2#KafkareplicationdetaileddesignV2-Deletetopic
Reassign partitions should delete the old replicas from disk
kafka intra-cluster replication support
creating topic without partitions, deleting then creating with partition causes errors in 'kafka-list-topic'
DeleteTopics gives Successful message even if the specified Topic is not present
Add delete topic to topic commands and update DeleteTopicCommand
