Ismael Juma commented on KAFKA-1694: ------------------------------------ [~sslavic], `AdminUtils` is communicating with ZooKeeper directly. The broker doesn't currently expose a protocol API that just checks if a topic exists. We are currently planning to make `listTopics` more efficient, but no immediate plans for a topic exists protocol API. Is there a use case where this is important? > KIP-4: Command line and centralized operations > ---------------------------------------------- > > Key: KAFKA-1694 > URL: https://issues.apache.org/jira/browse/KAFKA-1694 > Project: Kafka > Issue Type: New Feature > Reporter: Joe Stein > Assignee: Grant Henke > Priority: Critical > Attachments: KAFKA-1694_2014-12-24_21:21:51.patch, > KAFKA-1694_2015-01-12_15:28:41.patch, KAFKA-1694_2015-01-12_18:54:48.patch, > KAFKA-1694_2015-01-13_19:30:11.patch, KAFKA-1694_2015-01-14_15:42:12.patch, > KAFKA-1694_2015-01-14_18:07:39.patch, KAFKA-1694_2015-03-12_13:04:37.patch, > KAFKA-1694.patch, KAFKA-1772_1802_1775_1774_v2.patch > > > https://cwiki.apache.org/confluence/display/KAFKA/Kafka+Command+Line+and+Related+Improvements -- This message was sent by Atlassian JIRA (v6.4.14#64029)
