Was this taking a MongoDB database app and pointing to CosmosDB or was this developing a app around CosmosDB's partitioning etc but using the MongoDB API for read/write?

The former, lift and shift scenario I can understand as you need to structure your data to work best with CosmosDB/DynamoDB etc. If it's the latter that is useful to know as I'm currently building a POC on Azure so I should watch out for it.

Yes, so not the ideal use case. The compatibility Cosmos offered was nice and didn't present any issues, it's just the performance that suffered.

This was all part of a benchmarking exercise to figure out how to scale an app with minimal changes so we expected some performance penalty, just not as steep as what we observed.
