I wanted to create a compound unique index using 2 fields, but one of those has a path to some inner field like evaluated.rut. But I got an error:
I don't get the error, in MongoDB I had created index like that, but I can't now in CosmosDB, any suggestion?
Provided the nested path is not an array, the support for this is coming out very soon using the value EnableUniqueCompoundNestedDocs in the capabilities property array for a Cosmos DB databaseAccounts resource in ARM.
This is not yet publicly available. If you'd like to try today you can open a support ticket and ask this capability be added your Cosmos account. You can also DM me on Twitter (see my SO profile) and send me your Cosmos account name and I can request it for you.
