Hi Robert,
I’m aware of that post, and also the fact that it is not up to date; CosmosDB launched support for Mongo API 4.2 in Feb '22 and the post is based on the feature set in August '21. Also, the post doesn’t mention anything about RABC. In any case, I do need to use CosmosDB so it doesn’t really matter.
Regarding asking a Microsoft forum, AFAIK it is the MongoDB community building the Kafka Connect connector, not Microsoft. I’m used to address open-source developers directly in Github and/or specific chats instead of general forums. I assume tor developers might monitor this forum, since it’s linked in the Github readme.
Thanks.
