---------------------------------------
lindong28 opened a new pull request #4694: KAFKA-6640; Improve efficiency of
KafkaAdminClient.describeTopics()
URL: https://github.com/apache/kafka/pull/4694
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). This patch improves the complexity to O(n).
