Subject: [OASIS Issue Tracker] Commented: (MQTT-13) Topic name has an upper length limit of 32,767 characters ?


    [ http://tools.oasis-open.org/issues/browse/MQTT-13?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=33651#action_33651 ] 

Rahul Gupta commented on MQTT-13:
---------------------------------

updated section 3.3.2.1 in WD-04
----------------------------------------------

The Topic name MUST be a string which can be encoded as UTF-8 up to 65535 bytes in length. The Topic name MUST not contain wildcard characters. When received by a client that subscribed using wildcard characters, this string is the absolute topic specified by the originating publisher and not the subscription string used by the client.

> The topic name is a UTF-encoded string. See the section on MQTT and UTF-8 for more information. Topic name has an upper length limit of 32,767 characters.

> --------------------------------
> The following principles apply to the construction and content of a topic tree:
> > The length is limited to 64k but within that there are no limits to the number of
> levels in a topic tree.
> Should the topic length on PUBLISH command be restricted to 32,767 characters ?
