  1. Offline version for mobile devices

    Like cloudant and couchbase. To be able to have local storage which can sync with the cloud once we get a network conneciton.
    It should be connection agnostic, use in the same manner if connected or not.

  2. Integrate with Azure Active Directory

    Really need to be able to set resource level access control integrated with Azure Active Directory. The current built-in user / resource access control is a pain to use and we end up with just using the master key and giving everyone access to everything.

    Azure SQL DB already has this, and is a pleasure to work with.

    Perhaps you should take a leaf from your sister team on this -

  3. 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. Increase resource token validity limit (or) Provide authentication

    There is a user in a database. I would like to give the user, permission to the whole database resource for the lifetime or few months. So i would create a permission for the user for the database resource and use the resource token in this scenario. But my resource token expires in 5 hrs. So it would be helpful if token validity is increased .

    This feature may end up similar to authentication in other relational databases where the resource token may act as the username and password. The best approach can be decided either to have authentication (or)…

  6. add DocumentDB to the "azure stack"

    Azure Stack is a great Microsoft vision to allow running Azure applications on premise...
    but DocumentDB support is mandatory (unless Microsoft want to push MongoDB version 3)

  7. Increase 10GB limit on non partitioned collection

    Give there is a hard 10GB limit on a non-partitioned collection, and partition collections are much more expensive, with no auto-upgrade and code changes required to migrate to partitions, a larger size limit on non partitioned collection is much needed.

  8. Encryption via Key Vault

    Provide ability to encrypt data at rest using provided keys using Key Vault. This is a frequent requirement for storing anything related to the business, especially finances.

    Keys will be managed by customer in that case.

  9. 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.

  10. 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.

  11. 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.

  12. 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.

  13. 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.

  14. Increase storage limit per logical partition in unlimited containers

    I believe each logical partition is capped at 10GB regardless of whether it's contained in an unlimited container or not. Please give us the ability to scale up when needed so that we don't have to come up with yet another partitioning scheme. A logical partition should be able to hold much more than 10 gigs, in my opinion.

  16. Data masking feature in Azure Cosmosdb

    Request you to please add data masking feature to Azure CosmodDB to protect sensitive data like always encryption feature in SQL Server which allows clients to encrypt sensitive data inside client applications and never reveal the encryption keys to the Database Engine ( SQL Database or SQL Server). As a result, Always Encrypted provides a separation between those who own the data (and can view it) and those who manage the data (but should have no access)

    Hi Siva, thank you for your suggestion.

    There are a couple of aspects to your ask which I will address separately.

    We are planning on providing some additional capabilities to RBAC support in Cosmos DB that will separate Database Operators who can provision resources and rotate keys, versus an application which can access data but cannot provision resources or rotate keys. This is partially what you are asking for so want to bring this up.

    With regards to data masking and encryption…

    Today we support encryption of all data both in transit and at rest. This encryption is Microsoft-managed . At some point we will enable user managed keys but this is currently not on our roadmap.

    However users are fully able to implement client-side encryption and encrypt the data before it is sent by the client. This is fully possible today.

    The ability to offer this as a feature…

  17. More fine-grained permissions

    I'd love to see more fine-grained permissions. In particular, an 'Edit' permission would be extremely helpful. The user with an Edit permission would be able to change any of the data for the resource except the ID, and would not be able to delete the document.

    Use case: Provide users with direct but limited access to the DocumentDB database, rather than having to route all their requests through my own API.

  18. Different Access Levels for Cosmos DB

    Allow a set of keys for read-write or read-only that are restricted to the Collection level or the DB level. Enable multiple applications to have different levels of permission to a single Cosmos DB.

  19. Allow Activity Log Alert on Control Plane operations

    To be notified if someone deletes a collection unintended, i think it would be great to have an activity entry for collection removal. Right now, I only can set an event if the database is removed.

  20. whitelist ip - include a description

    Can we include a short text description for each white listed ip in the cosmos firewall settings - similar to azure sql server white listed ip settings

    It would make auditing so much easier, currently we have to maintain a seperate document showing which IP corresponds to what
