Re: [mosquitto-dev] Topic aliasing on messages sent out by Mosquitto

[Roger Light <roger@xxxxxxxxxx>]

Hi Vera,

That's an interesting idea - and easily achieved with user-properties.

I've just pushed a version to the develop branch which just limits topic to a maximum count, set to 10 by default.

Options max_topic_alias_broker and bridge_max_topic_alias are the ones to look at if you want to test it out.

Cheers,

Roger

yes.

I wonder whether the subscribing client shouldn't also have a say in
what topics it wants to be aliased in incoming messages. For example,
the client could set a "Topic Aliasing Requested" flag in the SUBSCRIBE
message and then the broker could do FCFS just for those topics. I know
this is not part of the spec so this is just a thought.

Best regards

Vera
