  2. How to limit the number of document updates?

    Hi
    I want to limit the number of document updates in one command.

    for example

    db.users.updateMany(
    <filter>,
    <update>,
    {
    limit : 100
    }
    );

  3. 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

  4. 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

  5. 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 }}
    ]
    }

  6. 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.

  7. 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

  8. 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.

  10. 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.

  11. 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?

  12. 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…

  14. I believe the future is for AI to assist the user in simple but sometimes frustrating tasks like connecting or finding the correct build

    An Artificial Intelligence assistance would be very useful to the user for finding the correct configuration and helping set up connections. There are many deprecated components, especially if you are trying to integrate a IoT platform like Raspberry Pi. It would be great for the system to recognize what you are trying to do and guide you along the right path.

  16. $addToSetIfNotExists or javascript code as array operator

    This would allow for unique if not last entry into arrays.

    Preventing:

    ['one', 'one', 'two', 'three']

    But allowing:

    ['one', 'two', 'three', 'one']

    Or perhaps (to run js code on the array at the db):

    `.update({}, {$js: {'array_field': 'var last = ""; for (var key in array) {if (array[key] === last) {array.splice(key);}}'});

  17. 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.

  18. views on different database (synonyms)

    It would be great if we could have in Mongo the same as in Oracle with DBLink synonyms:
    Access table or views from a different database.
