Subscribe/Publish filter is needed

Post by woshishuier »

For example, some subscribers care about topic A in some conditions, and other subscribes care about topic A in other conditions. So is there anything like subTopic or filter to decide which subscribers to publish to ? Thank you!

There isn't anything on the server-side (i.e. publisher-side), that would allow publishing to select subgroups of subscribers, within a topic. You could instead include some information in the published messages, and then let the clients use that information to determine if they should ignore the message or not.
