Public preview: Azure Cosmos DB API for MongoDB unique index re-indexing
Published date: 13 April, 2022
The unique index feature for Azure Cosmos DB allows you to create unique indexes when your collection was empty and did not contain documents. This feature provides you with more flexibility by giving you the ability to create unique indexes whenever you want to—meaning there’s no need to plan unique indexes ahead of time before inserting any data into the collection.
