There was a problem hiding this comment.
If app_id is None will this incorrectly leave a leading forward slash in the partition key?

I see below that it seems like the leading slash is okay, but I'll leave the question here to double check.

Fixes #2951
This adds support in the Azure Cosmos key-value implementation for storing multiple key-value stores in a single Azure Cosmos container.
IMPORTANT: This currently does not change the Spin CLI experience at all. Users of Spin CLI continue to have the 1 to 1 relationship between containers and key-value stores. This only allows Spin runtime embedders the ability to have many stores per containers. We can consider changing the default behavior for the Spin CLI in the future, but this might need to be at a major version change.
For embedders who provide an
app_idto theKeyValueAzureCosmos, stores will be created in the supplied container and each key/value pair will include a partition_key field in the form of "$app_id/$store_id".cc @devigned
