I need to setup CosmosDB Analytical Store and Synapse Link for my vCore based Cosmos DB Database for MongoDB. As it is not stated in the documentation, I would like to ask whether this is supported scenario.

I trued updating collection as stated here: #az-cosmosdb-mongodb-collection-update

az cosmosdb mongodb collection update --account-name xyz
                                      --database-name xyz
                                      --name xyz
                                      --resource-group xyz
                                      --analytical-storage-ttl -1

Nevertheless since account is not relevant in vCore tier the command fails when I use CosmosDB vCore cluster name instead.

There is also command

az cosmosdb mongodcluster update

but it does not provide possibility to enable analytical-storage-ttl which also enables synapse link. From this I assume there is no support for vCore, but I didn't find any explicit mention of this in Microsoft or other resources.

• It looks like Synapse Link is documented only under the NoSQL, MongoDB (RU), and Gremlin APIs. In the MongoDB vCore documentation, there is no mention of Synapse Link support. Based on this, it seems that this feature is not available for MongoDB vCore. You may want to check with Microsoft support or look for alternative solutions. If you see Azure Synapse Link is only available under the feature tab of MongoDB (RU) and not in MongoDB vCore check this image it also indicates that this feature is not available for MongoDB vCore. – Pratik Lad Commented 2 days ago

From the available documentation, Azure Synapse Link is explicitly mentioned only under the NoSQL, MongoDB (RU), and Gremlin APIs. However, there is no mention of Synapse Link support for MongoDB vCore anywhere in the documentation.

Additionally, if you look at the feature comparison section, Azure Synapse Link is listed as a feature under MongoDB (RU), but it is not present under MongoDB vCore. This further suggests that Synapse Link is not supported for MongoDB vCore.

To confirm this, you may want to check directly with Microsoft support or review any recent updates in the official documentation. If you're looking for similar functionality, you might need to explore alternative solutions depending on your specific use case.
