Allow hierarchical partition keys for containers

[ivanl-out]

Describe the feature.

Cosmos DB supports hierarchical partition keys.

When a container is provisioned, instead of using PartitionKeyPath, one can use the PartitionKeyPaths property to specify the hierarchy, for example, ["/TenantId", "/UserId"].

Unfortunately ContainerInformation in this persister only allows for specifying a single partition key to be specified, which is used to enrich an outbox record with the specified partition key value. This effectively means that for containers with hierarchical partition keys, outbox cannot be used.

Given that this might be a large amount of work to support hierarchical partition keys in this persister (or simply an array of partition keys per container, since the order of the partition keys probably doesn't matter for this persister), as a workaround, we will be using a synthetic partition key instead, but it would be great if support for hierarchical partition keys were introduced in future.

@ivanl-out, thanks for the suggestion. We have marked it so it can be considered for the next release.

Hi @cquirosj, could we expect this to be available in the next few weeks? Or do you think this will require much more time to be available?

@guibranco thanks for your question. We regularly release platform enhancements. However, we cannot commit to a specific release date for this feature, and we will not release support for it in the next few weeks.
