  1. Allow custom autoscaling policies

    Currently this is the following autoscaling policy in mongo:

    Please note, if the next highest cluster tier is within your Maximum Cluster Size range, Atlas scales the cluster up to the next tier if one of the following is true for any node in the cluster:

    Average CPU Utilization has exceeded 75% for the past hour, or
    Memory Utilization has exceeded 75% for the past hour.

    The feature request is to allow a DBA to setup custom autoscaling policy

  2. Conditional TTL index

    In case of auto purging sometimes user might want to ensure data has been archived before purging. If conditional TTL was allowed user could set value of a field to indicate document has been archived and then db can purge accordingly.

  3. Include schema validation events in changestream payload

    let's say my document has JSON schema validation like:

    {
  $jsonSchema: {
    properties: {
      phone: {
        bsonType: 'string'
      }
    }
  }
}

    and the validation action is set to "warning", if I do a command like: db.test.insert({"phone":1}), I would like the warning message to be included in my change stream.

  6. Data masking policy

    Implement Data masking similar to Schema Validation in Mongo so that customer can define a server-side data masking policy to mask the results of a query and a new role which will give explicit permission to users for reading unmasked data

  7. Deny Privilege

    Provide the ability to explicitly deny a privilege on a specific resource.

    Example: Grant the privilege to perform the find action on all collections in the test database except "test.secrets".

  9. String Json Parser

    lately, I imported a big CSV file, containing fields with values of Json object in String format, the simplest way to parse those strings to object it was by doing find().forEach( JSON.pase then update) it taken too much time to update the collection the only think that i have could done to reduce the latency is putting write priority to 0 which isn't very advisable with high throughput of updates, I don't really know for sure I'am not the expert here but working with big data demand a lot of cleaning, and not being able to do the cleaning on…

  10. Extend db.collection.distinct() to work with multiple fields in a compound key

    Currently the distinct() command finds the unique set of values for a SINGLE specified field across a collection or view. For example:
    db.staff.distinct("last_name" )

    If there is an index on the lastname field, the DISTINCTSCAN plan can use that index and the operation is very fast.

    To find the unique values for a set of more than one fields, the $group aggregation stage has to be used like this:
    db.staff.aggregate([
    {$group: {id: {FName: "$firstname", LName: "$last_name"}} ]);

    This operation does not really need the $group functionality, as it is not calculating a sum/min/max/average/etc value using the…

  11. TTL expiration on embedded subdocs

    TTL expiration on an embedded subdoc will delete the parent/root doc.

    Provide an option to only delete the subdocument on expiration.

  12. Allow collection collation to be editable

    Collation of a collection can be set at creation time only. It would be useful to edit these fields to avoid creating an entire new collection and copying the collection over.

  13. Reduce the minimum value for watchdogPeriodSeconds

    The storage watchdog attempts to create, write, and read a test file in critical directories every 10 seconds.

    The watchdogPeriodSeconds parameter controls how often these a thread checks to ensure at least one check has succeeded since the last check.

    The minimum value for watchdogPeriodSeconds is 60 seconds. This means that in the worst case, the mongod could be unable to write for up to 2 minutes before the watchdog asserts and kills the stalled node. That is a very long time for a primary node to be stalled in a busy cluster.

    It does make sense that watchdogPeriodSeconds must…

    wiredTiger open files usage

    Currently WT uses a file per collection and index, leading in some scenarios to extremely high number of open files/dhandles.

    Is there any plan to support one file/dhandle per database?

  15. Validation for referential integrity

    Currently, with the JSON Schema validation, we are able to limit the values for a field using enumerations. However, we need to have a way to limit the values to those entered in another collection.

  16. Allow multiple text indexes per collection

    MongoDb only allow one text index by collection, in contrast of other index types.

    This is a limitation that makes it difficult to develop projects with search functionality, for example, if you want to add a text search for advanced users on all fields and a public search on a subset of fields, there isn't a simple and performant way to solve it.

    Many developers end up using other products like elastic search, or creating additional collections and using lookup, or using preg_reg or building smart indexes when the creation of multiple text indexes per collection would allow a quick,…

  17. Ability to enable collection name enforcement

    Currently if you perform a find or other operation, and you have a typo in your collection name, the operation will execute successfully and there is no indication that the collection you are operating on doesn't exist. It would be handy if there were some sort of session variable that could be set that tells the engine, to return an error if the collection being operated on does not exist. For example, lets say we have a collection named "myCollection". If I issue a find with a typo in the collection name from the shell like:

    db.myCollectio.find();

    This will successfully…

  18. Ability to view and track collection wise transactions (read,write,success,failures)

    We have multiple microservices using the same collection and we'd like to track how many calls come from each, and also understand which transactions are successful or not.
    Ultimately this will allow us to understand the MDB usage by each of the microservices.
    [setting verbose logging level to 1 and then using these logs to create a dashboard in Splunk doesn't give us enough granularity]

  19. geoIntersects feature for 2D index

    At Airbus, we would like to use geoIntersects feature with 2D Index.
    We don't need 2DSphere Index, but we have to use it if we want to have geoIntersects avalaible.
    As a consequence, we have to manage Spherical margins which introduces a useless and hard to maintain workaround in our product.
    Could you please plan to implement geoIntersects and not only geoWithin with 2D Index ?
    Thank you

  20. Find all geoJSON points within a large collection of polygons. Reference collection in geoWithin.

    I would like to be able to find all geoJSON points located within a collection of polygons. My personal goal is to find points located within earth's water bodies. The water bodies are located in their own collection while the geoJSON points are located in a separate collection within the same DB. Mongo's geoWithin function only lets me hard code the polygons, but I would like to reference a collection of polygons.
