Kafka DeleteAcls Response Wire Format v2 — Binary Protocol Layout

What is DeleteAcls?

Revokes ACL entries via kafka-acls.sh --remove. Returns a list of deleted entries per filter; if the filter matched nothing, it's not an error. Be careful with wildcard filters as they can delete more ACLs than intended.
