  1. Efficient case-insensitive search

    At the moment, STRINGEQUALS with the case-insensitive flag requires a linear index scan over the property, so it is cardinality dependent, resulting in extremely high RU charges in large collections. Please implement a (perhaps optional) index that supports cardinality independent case-insensitive STRINGEQUALS. At the moment, the ugly workaround is to manually store duplicates of the property values in lower case.

  2. Emulator does not open data explorer if started with /NoExplorer

    If the emulator is started with /NoExplorer, then it will never open the data explorer even if explicitly requested to (i.e., right-click on icon, select "Open Data Explorer"). It would be better to have the /NoExplorer flag prevent the explorer from opening on startup, but allow it to be opened if explicitly requested.

  5. [CosmosDB] Be able to manage Backup and Restore with Portal and APIs

    Please provide the ability to manage backup and restore on our own.

    Restore through support is not clear and inconvenient.

    It turned out restore is only available through paid support plan.

    This document https://docs.microsoft.com/en-us/azure/cosmos-db/online-backup-and-restore#restoring-a-database-from-an-online-backup does not say it in any word.

    The situation made our customer extremely unhappy.

  6. Graph DB - more query tabs

    You should add more query tabs on CosmosDB for Gremlin, so that users can run different queries and compare the result without deleting every time the content of the textbox

  9. 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.

    We’ve recently announced a serverless model for Azure Cosmos DB – which we believe addresses use-cases with sparse but spiky throughput. Serverless enables billing based on a per consumed request unit basis – which goes 1 step further than managing provisioned throughput at a per minute granularity.

    We will continue to support the provisioned throughput model (along with autoscale) for use-cases that have high throughput utilization and/or require stronger guarantees w.r.t. availability and performance characteristics.

    For more information – please see: https://devblogs.microsoft.com/cosmosdb/serverless-preview/

  11. 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 -

  12. Add the ability to delete ALL data in a partition

    In a partitioned collection, it would be useful to have the option delete all data with a given partitionId.

  13. Add more options for GraphSONMode

    Currently I am using the GraphSONMode.Normal to get adjcency information of a 'vertex' but then I only use the outgoing edge information and ignore the incomming edge information.

    From optimization point of view we should add more options to have more fine-grained control on the output format of the gremlin query.

    I would like to suggect that we add 'IncludeOutE' option for GraphSONMode to return GraphSON format including only Outgoing edge information and 'IncludeInE' option to return GraphSON format including only Incomming edge information.

  15. 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.
