Getting info about existing subjects in stream

[BinaryArchaism]

Hi!

I have stream with subject info.*.> and few publishers (e.g. info.first_pub.super_info, info.second_pub.super_info, etc). So I want to get all info from this info.*.> except info.first_pub.super_info, how can I do it?

One of solution that came to mind is to subscribe to info.*.> and simply ack every msg of unnecessary subject without reading it. But I think this is not really good solution.
May be I should create subscription for every info.*.super_info except unnecessary, but how can I know full name of other subjects? Stream only give info about subject info.*.>

Thanks!

Consumers with multiple subjects are coming in 2.10 that might provide a solution.

Thank you for answering! But I'll still need info about existing subjects on the stream to collect them and create a multiple subject consumer except subjects I dont need. The stream config shows only wildcard subject, but not a real existing one. The stream state shows number of subjects only

"config": {
  "name": "info",
  "subjects": [
      "info.*.>"
  ],
...
"state": {
  ...
  "num_subjects": 6,
  "consumer_count": 1
},

So I think it will be great to have multiple subjects consumers but it's not a fully solution for such problems.

The StreamInfo call has an option to return subject details for all messages. So you will get a map of all subjects with the associated message count.
