Add Callback handler based on partition key, so polling is not needed/charged RUs
ChangeFeedProcessorBuilder does not support subscribing only to certain PartitionKeys, so it'd be great if you supported that.
If not, I can get by with GetChangeFeedIterator and manual polling (pull model), but that's in preview, so please release that officially.
I believe even in #1, we are charged RUs for polling behind the scenes (correct me if I'm wrong.) So idle host instances are constantly consuming RUs. Is it possible to trigger Cosmos to call the registered callback handler only when something happens on the change feed --for the specified partition key. A trigger replaces polling. Then only charge RUs for…
1 voteThank you while we reviewed your request.
We have no plans on adding the capability you have asked for #3. We will review this in the future and update if our plans change.
Thanks.

Delete notifications for change feed
Delete notifications for Cosmosdb change feed.
Problem:
When deleting an item in Cosmosdb it is not conveyed to the change feed.Proposed solution:
Implement a delete notification in the same manner as for upserts.
If the deleted item could be conveyed it is good but the id is better than nothing.If it helps I wrote a tad more here: https://www.selfelected.com/cosmosdb-change-feed-and-deleted-items/
90 votesUpdate: No ETA on this. Previous update was incorrect. Work has started. Will update when we have an ETA.
Thanks.
Work on this item has started. Approximate ETA for Spring 2020. Will update as this progresses.
Thanks.

First Class Support for Create/Update Differentiation w/i ChangeFeed
Add a mechanism to determine the type of change feed event being processed. Actions (e.g. Create/Update/Delete) should be accessible via the FeedResponse<T> (for the .net SDK) for each document.
In addition, CreateDocumentChangeFeedQuery should allow for filtering by these new action types (w/i the DB). Perhaps other [document-level] criteria should be supported too.
93 votesUpdate: The ETA for this has not been set. This is actively being worked on but cannot provide ETA.
Our apologies again. We are looking forward to shipping this feature.
Thanks.
Quick update. Apologies for the long time on this. We are looking to ship this in Spring 2020.
Thanks.
