  1. Get current RequestCharge inside stored procedures and post triggers

    It would be nice to be able to access the current 'RequestCharge' value (as it appears in the final response) from within a post trigger or even a stored procedure.
    It would allow for easier cost monitoring mechanisms on the developers' side.

  2. Partition keys should propagate to newly created vertices

    Assume a pre-existing graph whose vertices are on different partitions (and thus have different partition keys).

    Now, consider adding new vertices through new edges in bulk through the Gremlin API, e.g. like this:

    g.V().addE('l').to(__.addV('newVertex').property('PartitionKey', 'p')

    This would work just fine but it would possibly place the source and sink vertices into different partitions. If we would want them to remain on the same partition, we're currently lost with CosmosDB.

    The Tinkerpop API allows the property-step to specify a traversal, so the following query is actually possible in the Tinkerpop reference implementation and would solve the issue:

    g.V().as('source').addE('l').to(.addV('newVertex').property('PartitionKey', .select('source').id())

    This…

  3. DATA QUALITY: Please support graph transactions.

    Today, if a traversal fails at step n of m, figuring out what state the graph is in is quite a chore. As a result, all data modification traversals have to be written to support retries. Unfortunately, if the retrying component fails, the network fails, or something else fails, which prevents retry, the graph is left in an unknown state.

    Hello and thank you for your suggestion.

    While Cosmos DB provides support for transactions within a partition, we do not have support multi-step, cross-partition or distributed transactions.

    We recommend to customers requiring transactions across multi-step operations to coordinate these using the consistency model and optimistic concurrency control.

    Thank you for your suggestion.

  4. Support ST_Buffer Spatial Function

    This is a great function I use frequently in SQL Server. It lets you to generate an area around a point. It makes Radius Searches much easier and flexible. I like to see this in Cosmos DB to make radius searches better.

  7. Add geospatial aggregate functions like ConvexHullAggregate

    Looking for a way to compute the bounding box of some features based on a query. For example SQL has https://docs.microsoft.com/en-us/sql/t-sql/spatial-geography/convexhullaggregate-geography-data-type?view=sql-server-2017

    Of course I can download all the documents and compute this, but I think it would be more efficient to let Cosmos DB perform the calculation on the server.

  8. 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

  10. Better documentation and examples for Azure Cosmos DB Data Migration tool

    I would like better documentation for the Azure Cosmos DB Data Migration tool to ease migration to Cosmos DB from other data sources as these impedes migration of brownfield developments.

    If you are mapping LEFT joins from sql to arrays or collections of objects this documentation is missing from instructions. The below post is the only starting point for some

  14. Table Strorage JAVA SDK Performance Tuning

    Table Storage JAVA SDK does not provide concurrency option for any of its operation. We are getting TPS of around 500 for table insert queries but it is also because we have designed our data model such that.
    Async functionality is available for Table Storage C sharp SDK but not for JAVA SDK.
    It would be good if there is concurrency option for Table Storage Java SDK.

    Hello Anton. Thank you for your suggestion. Yes, the rate limit graphic is overly aggressive. We are planning to change that behavior so it more closely maps actual rate limiting.

    This work is planned but we do not have a precise ETA. Will update here either when this is started and for sure when it is complete.

    Thank you for your suggestion.

  20. Manage parallel processing server side

    If I run a query like "SELECT * FROM d WHERE d.field = "x" against a parallel database I expect the DBMS to run that query against each partition at the same time and return a set of collated results. As apparent from the REST API, it appears that such a query is only executed against 1 partition at a time. This means that to get proper parallel processing the client has to work out the partitioning, fire multiple queries and do the collation client side. To some extent this appears to have been encapsulated in the SDKs.

    To me,…

    One of the goals for parallel query execution in the client-side was to support low latency query execution. We’ve since added support for parallelism in the SDKs.

    We are planning to add support for REST API of all queries for workloads that need to reduce client CPU utilization.
