Question

Cosmos with mongodb (vcore) in a golang environment?

Johan Westerlund 21

Hi our team here at Solidicon has trouble understanding what client to use in a golang environment when using Cosmos with mongodb (vcore) version, we hear and read different answers. we hear that the official "mongo-driver" works fine but then we get trouble with azure when cosmos deside to change master node since mongo-driver cannot handle switching of write node when that happends. what is the recommended way to work with Cosmos with mongodb (vcore) in a golang environment?

@Johan Westerlund Thank you for reaching out.

In mongo vcore you always have one primary node, optional HA, and optional cross-region replicas. The Mongo drivers are the way to go.

Mongo vCore is an OSS Mongo compatible database. It's a managed version of OSS DocumentDB: DocumentDB: Open-Source Announcement - Microsoft Open Source Blog

I am not sure we are missing something up. I would like to get more details on the issue you're facing with Mongo DB.

@Johan Westerlund Can you confirm the mongo-driver configuration? Are you using Retryable Writes and Keep-Alive Settings?
