view on nested array
- It is quite common to have nested array in documents in MongoDB.
- It is also quite common to have to "flatify" those arrays in queries.
Here is an example where we have a collection with consultants and their professional experiences.
consultant [{ name:"Toto", age: 25, experiences: [{ role: "Sofware Engineer", from: "2010-01-01", to: "2012-01-01", company: "CompanyA" }, { role: "Data Analyst", from: "2018-01-01", to: "2020-01-01", company: "CompanyB" }] }]If we would like to list all experiences at a company during a certain period of time, we would have to do an aggregate query with 3 steps that are sometimes…

Low latency Change Stream for Global Cluster in Atlas
our event-driven applications need to publish events to Kafka triggered by Change Stream feature. It works perfect in replicaset MongoDB cluster.
However, after migrating to Global Cluster in Atlas, the Change Stream cannot keep low latency because of ordering reason among shards.
The latency may go up to 20 seconds when for a single change event.It would be nice if application can receive Change Stream from the single shard only (not care about ordering among shards) to prevent latency.
The idea is to pass "location" options when starting the Change Stream cursor.

updateMany limit
When porting an application backend from an RDBMS to MongoDB, we've spoken to two people who've are looking for a way to specify a limit on the number of documents in .updateMany(). I understand the behavior cannot be defined on a sharded cluster, but if we had a way to do this on an unsharded collection, that would help when dealing with these teams.

Option to prohibit a non-voting member from becoming a sync source of a voting member
Hi,
Our proposition in a few words: add a replica set option to allow chained replication but with the following exception: a non-voting member cannot become a sync source of a voting member under any circumstance.
This proposition would allow chained replication for clusters having both w=majority writes and analytics nodes.
Right now, those clusters cannot safely enable chained replication, because under some circumstances, the non-voting analytics member may become the first secondary in a serial chain of replication. In that case, this node[*] slows down the replication process for all downstream secondaries. Higher replication lag translates to extremely slow…

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.

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 you3 votes -
Automatic Indexes
MongoDB can already suggest useful indexes. Why not take the next step and allow MongoDB to autonomously create and manage indexes. Ideally it will automatically maintain the indexes over time as the structure and usage of the database changes.

Coordinate Releasing Better
When Mongo releases a new version, the downloads, release notes, and version selection in the support portal are never in sync and sometimes out of sync for weeks.
An example right now is 7.0.20. It has been out for a while. If I update via my OS's package manager, I get 7.0.20. Is 7.0.20 in the release archive download page? No. Does it have any published release notes? No. Is it selectable in the Versions list at support.mongodb.com? No. In fact, 7.0.19 is still not selectable there.
This is very frustrating and causes a lot of workflow/process issues. For example,…

Validation should support default values
Various users feel that validation should support default values. See, for instance:

mongodump - add support for nsInclude/nsExclude
Currently mongodump supports the excludeCollection/includeCollection options but this requires the use of the --db option. It would be useful if mongodump was able to dump all databases, as it does by default, but also be able to specify a collection or collections not to dump.

Leveraging Group By/Distinct Query to use regular Index
When using Group By or Distinct queries on database, provide the ability to leverage existing index
i.e these queries today will miss using existing index
db.collection.distinct("field")
db.collection.aggregate([
{ $group: { _id: "$category", count: { $sum: 1 } } }

Disallow new connections that don't specify an appName field
Currently as a DBA it's sometimes hard to identify which service is causing load on a shared cluster/database. Some people connect for adhoc workloads but don't specify an appName making it hard to track back to the owner. It would be useful to require appName for connections to a cluster to enforce this behavior.

Add support for Atlas Search via Stable API
In the aggregation pipeline, the $search stage is very helpful in developing my organization's application's functionalities. But using the Stable API or Versioned API, as it was once called, I am unable to use the $search stage as it is a part of Atlas Search and not a core MongoDB Server function. I would like to request that the support for Atlas Search be added to Stable API. This will allow my organization to seamlessly upgrade the server without breaking functionality. Other workarounds are not possible for us. Please do consider this as a feature for current or future versions…

Allow to decrease time series granularity and custom bucketing values
In our IoT use case, we are leveraging MongoDB’s time series functionality. Due to high write volume, we need to adjust the timeseries.granularity and bucketMaxSpanSeconds parameters to manage the write load. However, after increasing the bucketMaxSpanSeconds, we need to run the system for several days to observe stability. If the value is set too high, MongoDB does not support decreasing the bucketing value, and we are forced to create a new collection instead.
It would greatly simplify our testing process and increase flexibility in adapting to business changes if MongoDB allowed the decrease of bucketMaxSpanSeconds after it has been increased.

Metadata (Created Date) for database accounts
We frequently have audit questions about when a given user was created in our Mongo databases. Other DBMSs (Oracle, for instance) have a 'CREATED' field in a metadata table (i.e. DBA_USERS) that shows when a user was created, and this would be very helpful when responding to these audits.

log redaction customization
If we have customizations on the log redaction feature then we can add our preference where we have to apply log redaction. As of now according to my opinion it is getting applied on the all log fields which may create a issue while troubleshooting the any issue.

Named MongoDB Connections
When a service is acting erroneously and generating hundreds or thousands of connections, it's currently difficult to determine which service is doing so when you have 30+ services connecting to MongoDB.
My proposal is that we should be optionally able to specify a non-unique name for the connection in the MongoDB URL (possibly after a #), which would allow DB administrators to see how many of each named connection was connected at any given time, and also other metrics (operations/s per name, average/max query execution time per name, etc.).
Example URL:
mongodb://user:****@clustername.abcd.mongodb.net:27017/dbName?authSource=admin#myServiceName2 votes
