Azure CosmosDB MongoDB: WriteError - Request timed out

With my team we use the Azure Cosmosdb Mongodb service, and we are attempting to perform a deleteMany() operation. We get the following error:

$ mongo <connection-string> --eval 'db.trainingData.deleteMany({"data.intent" : "FIN INTENTION STANDARD"})'

. . .
. . .
. . .

WriteError({
        "index" : 0,
        "code" : 50,
        "errmsg" : "Request timed out.",
        "op" : {
                "q" : {
                        "data.intent" : "FIN INTENTION STANDARD"
                },
                "limit" : 0
        }
})

We have disabled throughput limiting on our Azure Cosmosdb instance but it doesn't solve the issue

Any idea as to why this is not working?

It turns out the issue came from throughput limiting at collection level, which I didn't know was a thing in Azure CosmosDB

By default throughput is limited to 400RU/S (Rate Unit per Second) on every collection

enter image description here

We switched it to Autoscale with a max limit of 10.000RU/s on the few collections involved, and it fixed the timeouts
