Hey @blankensteiner happy new year to you! Any ETA on this?

[blankensteiner]

Hi @eaba Happy new year! :-) I will talk to some developers at Danske Commodities on Monday. If memory serves me right, I think this might be something that we are gonna use in Danske Commodities. @kandersen82 maybe you can confirm?

[eaba]

If we can get this - I will let you "sleep".

@blankensteiner There may be some synergies between implementing partitioned topics and this, since subscribing to a partitioned topic would require subscriptions to multiple partitions in some cases.

Partitioned topics are a priority for us, but multi topic subscriptions are not.
