This is not on our roadmap and we have no plans for it long term.
Thank you for your suggestion.
This is on our long term roadmap and are still evaluating this but no ETA. Will update as this changes.
Thank you for your suggestion.Ste Wilson commented
I agree. With cosmos you are encouraged to put multiple document types into the same collection / partition so they can be update together in a sproc transaction. The down side to this is then you subscribe to that collections change feed and you’re probably going to get a lot of function executions for changes you are not concerned with. This impacts scale and cost making it less viable. A filter on what causes the trigger to fire would solve this.
so we should expect this by the end of October?
Please can you update if your not going to hit this.
Work on this feature has started. Will update here when this becomes generally available.
Thank you for your suggestion and votes.
