Date Mon, 12 Mar 2018 23:26:00 GMT

     [ https://issues.apache.org/jira/browse/KAFKA-6640?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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))
