Enabling Mongo DB Aggregation Pipelines in Cosmos DB via Code

Question

It's really neat that Azure Cosmos DB now also supports Aggregation Pipelines, and this makes it a viable replacement for us to use instead of running our own Mongo DB Containers, but I have failed to find a way to enable the features via code (how to do it in the Portal is described here: https://azure.microsoft.com/en-gb/blog/azure-cosmosdb-extends-support-for-mongodb-aggregation-pipeline-unique-indexes-and-more/).

We need this for the integration and testing environments which we create via deployment pipelines from scratch every day, and the backing Cosmos DB instances must support Aggregation pipelines.

I have checked the API documentation at https://learn.microsoft.com/en-us/rest/api/documentdb/, and also the az cosmosdb command line tool, but I can't find the right setting to pass in.

Has this just not yet surfaced, or am I missing something?

You can track the change with the following pull request: https://github.com/Azure/azure-cli/pull/5451#pullrequestreview-94854631

The following command will allow you to enable aggregation pipeline.

az cosmosdb update -n {acc} -g {rg} --capabilities EnableAggregationPipeline
