placement of mongosh,mongo tools and mongo binary inside core bin
Hi Team,
Hope you are doing great!
Didn't understand the purpose of keeping mongosh,mongo tools and mongo binary separately, can't this be place in a single rpm/tar file so that it can be easy the installation process.
As per the current :
Mongo binary location :/var/lib/mongodb-mms-automation/mongodb-linux-x86_64-6.0.8-ent/bin
Mongo Tools location :
/var/lib/mongodb-mms-automation/mongodb-database-tools-linux-x86_64-100.7.4/bin
Mongosh location :
need to keep this file in separate location and access the mongodh. mongosh-1.10.1-linux-x64.tgz
Thank you

Allow rotation of Arbiter TLS certificates when authentication is enabled
Mongo arbiters do not support using db.rotateCertificates(), because they do not possess the internal table of user and role mappings used for authentication.
Add functionality to enable rotation of these certificates.

Exclude PDB files from installation
mongod.pdb is nearly 1.0GB, mongos.pdb - 0.5GB
Since these fils are not necessary for the server to function properly, they should be optional, e.g. provide a checkbox to exclude them during installation.

DB Snapshot triggers when RDS Snapshot starts.
Looking for a feature regarding DB Snapshots, so that we can configure a Snapshot Policy to be triggered whenever a specific AWS RDS snapshot starts (for the daily schedule).
Thank you in advance.

Allow live migration using private interface
There should be an option to live migrate data via a private interface instead of public one. With VPC being peered, it would be a great option to avoid exposing database to the public interface (even if it's specific set of IPs). This can resolve concerns of many customers who are following or need to follow some short of compliance on their end.

an aggregation stage to load data to DRAM for the fields that are only requested
When we use $project stage, it loads whole document from disk to memory (if not in working set). Because of this, When we create a data model, We have to create separate collection if the field is not required in frequent access of data. Creating a view is an option, but what if $project itself or $project with some argument in it, or a new pipeline stage or operator gets introduced which fetches the data from disk only for the fields specified instead of loading whole document.
With memory mapped file, retrieving fields specified alone would not be simply possible…

When was last backup/mongodump ran on databases or database backup history
How can get detail of last backup was taken using query. Its very hard to get into log file and see the history of mongodump. Just like other database tool mongodump history can be retrieved via query instead mongo log file.
I know get the detail from ops manager if using enterprise only but what if we are using community edition.
If you include this feature it will very helpful for DBA to get the details juts like other database tools available in market.

$group all fields
$group should have the ability to allow specifying all fields in a document (without explicitly defining them all, which can lead to duplicating dozens of lines just to do "key: $first")
This will help users that use $unwind and then want to $group the results without having to do a subsequent $lookup and $mergeObjects (or similar) to get the final document structure they're looking for.

Amazon Linux 2023 Support for MongoDB 6.0 and OpsManager 6.0
Amazon Linux 2023 is supported in rapid releases from 6.2.0 and will be supported in the upcoming 7.0 release of MongoDB, however it appears there is currently no plan to support AL2023 for the 6.0 release of MongoDB. Can support for AL2023 be added to the 6.0 branch for both MongoDB and OpsManager?

Support indexes on single array elements (e.g. "MyArray.0")
Currently, if I create an index on an array field and specify an element number ("MyArray.0"), the system still indexes the whole array as normal.
Normally, this might increase the index size but at least it's still useful when querying MyArray.0 later.
However, it would be better to be able to index individual numbered elements in cases like compound indexes where I might need to check whether two arrays are non-empty, and I can't use a compound index for a query on MyArray.0 and MyOtherArray.0 at the same time due to the multi-array limitation.
For MongoDB folks with access to…

Collection which stores last login date_time for the users
Are you please able to store the last login date_time for the users which exist either in admin database or $external database in a collection of admin database of that cluster or opsmanager database which manages the clusters?
I have a requirement at my end - is to find the users who havent logged in for 60 days, , their roles to be revoked. And, ultimately delete the users who dont have any roles attached after a fixed period of time.
I do undertsnad you store the login details in audit logs. But that would be a tedious process at…

Add timestamps to user documents
Most database technologies store this metadata by default.
Because the expected data volume and change rate of this attribute will most probably be low, there should be no reason of not storing this information.
Of course this information might already be available in audit files, but first: auditing isn't enabled by default.
Second: most database users won't have access to this file/info and third: most users won't expect this info in a separate file (reminder, MongoDB recommends to store the data where it belongs when it comes to "data/schema modelling", so the metadata of a user document should also be…1 vote -

Change stream Monitoring/Aletring in management
how to monitor change stream activity per namespace
1. Number of Change streams per namespace
2. Set + Manage the allowed number of change streams
3. A metrics UI tab for OpsManager.
4. Alert if the number of change streams exceeds the set limit.This will assist in managing the cluster and also avoiding any issue that may arise from highly demanding change streams that take up RAM and compute.

Cascading delete for DBRefs
Since transactions have been added in 2018, which work across collections (https://www.mongodb.com/docs/manual/core/transactions/) and across shards (https://www.mongodb.com/docs/manual/core/transactions-sharded-clusters/), shouldn't cascading deletes be possible now? I only worked with sql transactions in the past, but my intuition would be that it should be fairly easy to do this in a client:
- start a transaction
- fetch document
- look for dbref fields
- fetch those docs
- continue at 2 until all docs have been found, stopping at branches when a doc has already been fetched
- go back in reverse and delete all of them
- commit transaction
If this is possible to do…
