[jira] [Updated] (KAFKA-1674) auto.create.topics.enable docs are
misleading
[ https://issues.apache.org/jira/browse/KAFKA-1674?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Stevo Slavic updated KAFKA-1674:
--------------------------------
Description:
{{auto.create.topics.enable}} is currently [documented|http://kafka.apache.org/08/configuration.html] with
{quote}
Enable auto creation of topic on the server. If this is set to true then attempts to produce, consume, or fetch metadata for a non-existent topic will automatically create it with the default replication factor and number of partitions.
{quote}
In Kafka 0.8.1.1 reality, topics are only created when trying to publish a message on non-existing topic.
After [discussion|http://mail-archives.apache.org/mod_mbox/kafka-users/201410.mbox/%3CCAFbh0Q1WXLUDO-im1fQ1yEvrMduxmXbj5HXVc3Cq8B%3DfeMso9g%40mail.gmail.com%3E] with [~junrao] conclusion was that it's documentation issue which needs to be fixed.
Please check once more if this is just non-working functionality. If it is docs only issue, and implicit topic creation functionality should work only for producer, consider moving {{auto.create.topics.enable}} and other topic auto creation related configuration properties (docs only, but maybe code also?) from broker configuration options to producer configuration options.
