Dong Lin updated KAFKA-6640:
----------------------------
Description: Currently in KafkaAdminClient.describeTopics(), for each topic
in the request, an complete map of cluster and errors will be constructed for
every topic and partition. This unnecessarily increases the complexity of
describeTopics() to O(n^2). (was: Currently in
KafkaAdminClient.describeTopics(), for each topic in the request, an complete
map of cluster and errors will be constructed for every topic and partition.
This unnecessarily increases the complexity of describeTopics() to O(n^2). We
can improve its efficiency to O(n))
