  1. Set based operations (INSERT, UPDATE, DELETE)

    It would be nice to be able to update parts of documents, delete documents, and insert documents using set based operations, similar to SQL.

    e.g.
    UPDATE Users SET IsActive = 0 WHERE LastLogin < '2010-01-01'
    DELETE FROM Users WHERE LastLogin < '2009-01-01'
    INSERT INTO table2 SELECT * FROM table1

    There are multiple responses to this suggestion.

    Support for SQL-like syntax for UPDATE, DELETE and INSERT INTO are not on our road map at this time.

    However, the underlying functionality for an UPDATE, SET is essentially a PATCH. This functionality we are actively working on. See this User Voice item here to track for future updates. https://feedback.azure.com/forums/263030-azure-cosmos-db/suggestions/6693091-be-able-to-do-partial-updates-on-document

    Thank you for your suggestion.

  2. Built-in OAuth support

    Support OAuth to make it easy for mobile clients to securely talk directly to DocumentDB without a middle tier or a separate resource token broker.

  4. Move RU throughput allocation from Collections to Database Level and viceversa

    We have multiple databases with many collections and would like to move the throughput allocation from single collections to Database level without recreating it and migrating everything.

  5. Configure RU per region

    For a database/collection that is made available in several regions, make it possible to provision RU capacity independently in each region. Use case: Secondary backup region that exists only as an up-to-date mirror of data in case the primary becomes unavailable, not to offload read operations under normal operation. Currently this means provisioning unused RU capacity, at a high cost, in the secondary region.

    Hi Magnus. This is currently unplanned by us for our road map. Some context and feedback for you on this.

    First, to do the replication itself to the secondary region you need RU/s sufficient to support the request rates for the primary region itself. Replication and writing to the secondary region itself is not free so there needs to be sufficient throughput provisioned to do that.

    Second, for the secondary region to be able to function as the primary should a fail over occur, the replica region itself needs sufficient throughput to function as the primary.

    Thanks again for your suggestion. Will mark as unplanned for now in case circumstances ever do change.

  6. Implement a GraphQL Provider (repost)

    (Previous post with the same title was closed without giving the correct solution.)

    graphql {http://graphql.org/} is becoming increasingly adopted by front end frameworks (including mobile) for querying backend / API data.

    Rather than having to translate each graphql query into a DocumentDB client call it would be optimal and very powerful to issue the query directly.

    It would also provide enhanced query abilities over the existing REST approach.

  7. DocumentDB project for Visual studio like existed SQLServer project.

    It's would be valuable if we will can save all collections and related scripts in a new type visual studio project. Now only in a database we can observe UDFs, triggers and so on.

    Another option for a project could be compare .js objects in a collection. With a project we would have a chance to compare already deployed versions of our scripts with current developer version of the script.

  8. Pricing Granularity per Minute instead of per Hour

    It is buried in the FAQ;s on the pricing page. The current billing structure will take the largest RU offer in a given hour increment and that's what is charged for that hour. If you scale up to 1000RU's at 10:59 and down to 400 at 11:01, the billing for both hours will be @ 1000RU's. This makes scaling up and down harder to deal with and reason about. Can you evaluate changing the billing granularity down to the minute level in order to allow shorter bursts of scale up / down billed for the actual usage.

    Thanks for your suggestion. Currently, we don’t have anything planned in changing our billing meter from hour to minute. But will leave this request open and will include this in future planning discussions for our roadmap.

    Thank you for your suggestion.

  9. Azure Cosmos DB: HBase API

    Add support to Azure Cosmos DB for HBase API. This will open up many Big Data use cases.
