  1. official Dart driver

    We use mongo in weebi Dart / Flutter application.
    We would be eternally grateful if you could implement an official Dart Driver,
    There is already an unofficial mongo dart repo :
    https://github.com/mongo-dart
    The specific feature we need is Ejson
    https://github.com/mongo-dart/bson/issues/29

    Thank you for building a great tool

  3. Allow to set default maxTimeMS for all cursors

    By default, a cursor has no maxTimeMS.

    We want to be able to set the default maxTimeMS so all cursors have it set. The current Java driver does not allow to set that default and each cursor needs it manually specified. I.e. a cursor factory or default options would be great.

    Alternatively, it would also be great to have this as an option on the cluster itself.

  4. Estimated Filtered Count

    Hi,

    We are currently using a pattern where we use a find(query).limit(x) and a count(query) with $near to find x results and display the overall count. Using this pattern, we are able to pass the same query to find and count. However that count method was removed in SCALA-517 and replaced by estimatedDocumentCount and countDocuments. The problem is that countDocuments will not work with $near. There is a workaround to use $geowithin with $center/$centerSphere, however this doesn't return the results sorted as $near did. We would like to have the option to pass the same query to count as we…

  5. CSFLE - Encryption of fields within an Array Object instead of whole Array

    CSFLE - Can you provide Encryption of fields within an Array Object as part of mongo-crypt library in the future releases. current library encrypts the whole array and we are not able to do queries within the Array object.

  6. csfle support for zOS

    Please modify your drivers so our java applications can encrypt and decrypt from the mainframe (zOS) UNIX environment. This missing feature is a road-block to our migration to Atlas.

    We have multiple Java applications that run on an IBM mainframe. Those applications read and write into MongoDB collections, like inserting Mainframe data into MongoDB collections. The mongo-crypt driver for CSFLE does not work on the Mainframe UNIX environment.

    Company policy states we have to encrypt all PHI/PII data prior to inserting the data into Atlas.

    I had opened a support ticket with MongoDB and the final reply was you do…

  8. It will be helpful to provide Sock Proxy support for our drivers

    Some customers have security policy restriction to directly connect to Atlas. So it will be helpful for them to use sock proxy to connect.

  9. Add a function for determining if a connection object is still healthy

    If an application needs to cache database connections to MongoDB. It would be helpful to have a function to call when retrieving a cached database connection. This function would ensure the connection is healthy before use. It could just return a boolean and allow the client application to handle a bad connection accordingly.

    Using a disconnected event handler is not always reliable especially with FaaS serverless functions.

  10. Make driver aware of Autoscaling

    Driver not aware of autoscaling (topology changes)

    This is related to https://support.mongodb.com/case/01186544. We are experiencing exceptions when autoscaling is supposed to work flawlessly. The problem seems to be that the driver checks for a heartbeat every few seconds but fails to do so under heavy bursts of workloads, which we are currently facing.

    When autoscaling kicks in, there should be a possibility to make the nodes aware that they have been scaled, so that when they communicate with the driver, they provide this information back to the driver. The driver would then explore the new topology first before throwing…

  11. Compressed Fields

    When large JSON structures are being stored but don't need to be queryable it may be more performant to handle the compression at the field-level as opposed to the network level (similar to what is described in https://medium.com/idealo-tech-blog/advanced-mongodb-performance-tuning-2ddcd01a27d2).

    This would isolate compression and decompression on the client side (unless network compression was used as well), however the compressed field would be persisted as-is (compressed) to the cluster.

  12. Allow custom service names with mongodb+srv URI scheme

    We are using DCOS (marathon/mesos) to manage our services. DCOS generates SRV records for our mongos instances under a record that looks like

    mongos-mongodb.tcp.marathon.mesos
    However, there's currently no way for me to use this because when I provide a connection url like

    mongodb+srv://mongos-mongodb.tcp.marathon.mesos
    the drivers prepend "mongodb.tcp" to the provided url. It's not clear why it's required that the host must start with "mongodb.tcp". Why not let the user specify the actual DNS entry to query?

    I believe the same issue will exist for multiple orchestration frameworks such as Consul/Nomad and Kubernetes.

  17. Take possible SerialName annotation into account for the query DSL (Kotlin)

    Hey,

    I'm talking about the kotlin-driver (there was no kotlin selectable in the dropdown, so I chose "Java" since the kotlin driver is based on the java driver).

    When using the kotlin-driver with kotlinx.serialization it's a bit complicated to write refactoring-safe queries, because when using the KProperty.name reference like in the examples of the documentation a possible @SerialName annotation is not considered.

    I'd like an API matching what KMongo provided that you can just reference the KPropery, and the driver under the hood decides whether to choose just the name or the value of a possible SerialName annotation.

  18. Client-Side Automatic Field Encryption - Support contacting keyvault via Sock Proxy

    When using Atlas from our application in our Datacenter, we are able to connect to it without issue.

    When adding CSFLE, some HTTP calls are made to login on Azure and access the AKV. These HTTP calls must go through a proxy.

  19. Dynamic Configuration Changes for Connections

    We would like to suggest a feature improvement where connection parameters can be dynamically changed so that no restart of client application infrastructure is needed.

    Currently, when changing connection configuration, this usually requires the restart of a considerable number of pods or containers with the unavoidable consequence of a sudden surge in connection attempts.

    Our request specifically would be to provide a way for drivers to read both connection string and connection parameters information from a source that can be easily managed and that's not necessarily embedded in the code, and

    Drivers should also detect when this configuration has changed…

  20. BsonIgnoreIfEmpty - Property Attribute

    Like BsonIgnoreIfDefault and BsonIgnoreIfNull, we can add BsonIgnoreIfEmpty.
    It can be added on IEnumerables (which we basically know they cannot have infinite values since it is inserted to db after all..) and if the IEnumerable is empty, it wont serialize it to the db BUT will know to put default value (an empty list for example) in said property.

    They will decrease below boilerplate code for IEnumerable<T>:

    Serialization:
    Field = otherField?.count > 0 ? otherFIeld : null;

    Deserialization:
    otherField = Field ?? new List<T>;

    Obviously, we can improve this code to also support Dictionary<Tkey, Tvalue>.
