Release notes with urgency and risk
Provide MongoDB customers/users with an understandable release notes, especially for bugfixes.
What are the risks this bugfix release covers, what is its urgency.Right now, release notes are made of MongoDB Jira tickets, which are very detailed and refer to the implementation of MongoDB, and thus cannot be easily understood by end users.
As a suggestion, release notes could sum up the following data in a simple table:
- Nature of impact
-> data corruption: yes/no
-> downtime: of a single node / of the whole cluster / on a subset of requests / etc
- Context of impact…11 votes -

connection
Hi,
it will be greatly appreciated to have an option to control the connections number when choosing an instance.
M30 is just what we need except for the connections number
we have around ~2.5k and max is 3k it would help a lot to have an option to increase just the connections number, so we wont need to move to M403 votes -
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…

TTL Support within a document
The current TTL implementation where documents can expire after a certain amount of time is extremely useful, especially because of its robustness in terms of if the db crashes.
I would love for this to be extended upon with the ability to allow data within a document to expire after a set time. So for example, if you add data to a document you could set that data and that data only to expire with its own time to live value

Support newer versions of JSON Schema in validation to be able to use the "if", "then", "else" and "const" keywords
Currently there is no way to have conditional schema validators because you can't use the "const" keyword in a "oneOf" or the "if", "then" and "else" keywords.

Providing connection details with username for real time connection monitoring.
Currently, mongd.log provides connection details like remote IP, source port with authentication information but doesn't provide the connection is in active state or not.
serverStatus() only provides number of current and active connections.Example:
10.0.0.100:12345 - username active
10.0.0.101:12346 - username idle2 votes -
Include or flag nodes seen more than once / duplicates when traversing with $graphLookup
When traversing a graph with $graphLookup, we suppress duplicates (in cases of cycles). It would be useful to have an option to include a flag indicating a node that caused the traversal to stop due to duplication.

We need to be able to use $[<identifier>] and "$setOnInsert" in the same command
I want to be able to have a maintain array of counters for a user through a single update statement. If the document containing array of counters does not exist, I want to add it. If it does exist, I want to increment the counter
For example, this command
db.inboxItemCounts.updateOne(
// filter
{
"userId": userDoc.userId
},
// update
{
"$setOnInsert": {
"userId": userDoc.userId,
"fromUserSummary": [{
"userName": fromUserDoc.userName,
"count": 1
}]
},
// "$inc": incBody,
"$inc": {
"fromUserSummary.$[userElement].count": 1
}
},
// options
{
"upsert": true,
"writeConcern": { "w": "majority" },
"arrayFilters": [
{ "userElement.userName": { $eq: fromUserDoc.userName }}
]

Preserve field order in $merge
Filed on behalf of https://jira.mongodb.org/browse/SERVER-63853:
A variety of formats require strict adherence to the sequence of fields, such as bioinformatics
Files of such formats are often very large and contain nested structures, so it is convenient to use them as collections. But to keep the data belonging to the above specs, it is necessary to keep the arrangement of the fields. Unfortunately, aggregations with saving results to another DB lose original arrangement.

Support hex conversion and binary operators in aggregation framework
The aggregation framework lacks function for HEX <-> Number conversion and binary operations. Such functions are common in almost every programming language.
Typically and most required operations would be:
- convert Int/Long to Hex
- convert Hex to Int/Long
- Create BinData from Hex string
- Get Hex string of BinData
- Binary AND
- Binary OR
- Binary XOR
- Binary NOT (i.e. complement)
Some of these functions are available in mongo shell or in Bitwise Query Operators but they do not exist in aggregation framework.
For details see https://jira.mongodb.org/browse/SERVER-55386
This request becomes more urgent, because starting in MongoDB 8.0, server-side JavaScript functions ($accumulator, $function, $where) are…

Write parts of database engine in ZIG
Zig is a zero-dependency, drop-in C/C++ compiler that supports cross-compilation out-of-the-box. Implementing some parts of MongoDB database engine core in ZIG might brings some performance improvements.

Self-Managed Computed Collections
This feature would enable MongoDB to automatically generate common patterns by computing entire collections. A particularly useful application would be the ability to identify duplicate fields within a collection and create a computed collection that groups all possible duplicate together.
Sometimes, a field is duplicated between two documents, while another field in the same document is duplicated across seven other documents. Each of these seven documents might have fields that are duplicated in yet other documents, leading to a vast iteration in search of possibilities.
Having MongoDB abstract all this logic in a performant manner to create computed collections would…

My account is stuck in "We are deploying your changes (current action: configuring MongoDB)" endless loop for the entire eveing and I cannot finish my project for tomorrow. Cannot connect to my database even with a saved IP.

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

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.
