1. csfle support for zOS

   Please modify your drivers so our java applications can encrypt and decrypt from the mainframe (zOS) UNIX environment. This missing feature is a road-block to our migration to Atlas.

   We have multiple Java applications that run on an IBM mainframe. Those applications read and write into MongoDB collections, like inserting Mainframe data into MongoDB collections. The mongo-crypt driver for CSFLE does not work on the Mainframe UNIX environment.

   Company policy states we have to encrypt all PHI/PII data prior to inserting the data into Atlas.

   I had opened a support ticket with MongoDB and the final reply was you do not support zOS and to put in this request. (Case number 00802484)

   Here is the error message I shared with MongoDB:
   Exception in thread "main" java.lang.UnsatisfiedLinkError: Native library (com/sun/jna/z/os-s390/libjnidispatch.so) not found in resource path (Ýfile:/sharedappdev/test/CD/apps/mongopoc/mongo40apps/,

2. Make The client model serializable

   I am working on a mongodb connector for the Apache Flink project - https://flink.apache.org/

   Internally, Flink is using java serialization to save the records it is working on in a state which in turn used to recover from failures etc, as well as for passing records between different tasks in the pipeline.
   I have noticed the mongodb client model classes are not Serializable for instance, classes such as WriteModel https://github.com/mongodb/mongo-java-driver/blob/master/driver-core/src/main/com/mongodb/client/model/WriteModel.java and its subclasses or the different Options like ReplaceOptions https://github.com/mongodb/mongo-java-driver/blob/master/driver-core/src/main/com/mongodb/client/model/ReplaceOptions.java

   is there a reason for these classes to not be declared Serializable? Is there a way to contribute to the Java driver project by opening a PR that addresses this?

3. geoContain

   Dear all,
   according to the attached image, I have some documents (in blue, with id from 1 to 5) having a geographic extent and a search area (in yellow).
   I need to find all documents where search area is completly inside the document's geometry.
   Using different words, I need to find all documents where geometry completly covers the given search area.
   In my sample, the geo query should return the document with id 1.
   This kind of query has a opposite logic than the $geoWithin

   Could you provide a $geoContain functionality in the next future?

4. Compressed Fields

   When large JSON structures are being stored but don't need to be queryable it may be more performant to handle the compression at the field-level as opposed to the network level (similar to what is described in https://medium.com/idealo-tech-blog/advanced-mongodb-performance-tuning-2ddcd01a27d2).

   This would isolate compression and decompression on the client side (unless network compression was used as well), however the compressed field would be persisted as-is (compressed) to the cluster.

5. Multiple collection ACID transactions

   Currently we can update multiple documents with one query if all documents belong to the same collection as shown below;

   dB.collection.bulkWrite([ query1, query2, query3, query4 ])

   This feature is wonderful but it is paramount if mongodb can enable us to use this query or something similar to update multiple documents from different collections with the one query instead of having to send and await each query one at a time as is currently the case.

   The truth is, mongodb only needs to enable this feature of being able to update multiple documents with one query from different collections and then it will certainly be superior to the SQL databases and will get much more market share.

6. Serve API endpoint for MongoDB Compatibility Matrix

   This is a feature request for website API calls/endpoints to retrieve the MongoDB Compatibility matrix for each driver language. For example, NodeJS is located here in HTML format https://docs.mongodb.com/drivers/node/current/compatibility/

   It would be helpful to have a programmatic endpoint for the same compat table results. This will help log parsers and aggregators to quickly identify applications and clients that are connecting to deployments with untested or incompatible client drivers.

9. Estimated Filtered Count

   Hi,

   We are currently using a pattern where we use a find(query).limit(x) and a count(query) with $near to find x results and display the overall count. Using this pattern, we are able to pass the same query to find and count. However that count method was removed in SCALA-517 and replaced by estimatedDocumentCount and countDocuments. The problem is that countDocuments will not work with $near. There is a workaround to use $geowithin with $center/$centerSphere, however this doesn't return the results sorted as $near did. We would like to have the option to pass the same query to count as we do to our find, even if there are risks associated as there was with count, an estimatedDocumentCount or unSafeCount, if you will, that accepts the same filter as our query.

10. Dynamic Configuration Changes for Connections

    We would like to suggest a feature improvement where connection parameters can be dynamically changed so that no restart of client application infrastructure is needed.

    Currently, when changing connection configuration, this usually requires the restart of a considerable number of pods or containers with the unavoidable consequence of a sudden surge in connection attempts.

    Our request specifically would be to provide a way for drivers to read both connection string and connection parameters information from a source that can be easily managed and that's not necessarily embedded in the code, and

    Drivers should also detect when this configuration has changed and gradually refresh connections to reflect the new configuration. Ideally there would be ways of forcing the driver to be more aggressive or more gradual, which should accommodate for emergency situations or tuning scenarios that are not urgent. This is the part that would avoid any client infrastructure restart, and avoid sudden surges in connection attempts.

13. Support "default" keyword in MongoDB's implementation of JSON Schema

    Without defaults, there is a need to iterate though each property just to check if a default value is needed (most probably this can be easily done on type check). Also without defaults we need to remember checking it both in inserts and updates (for example with $push operator)

16. Provide a direct download for current versions of driver files/dependencies on the official MongoDB sites

    Note: This post was inspired by my attempts to find a direct download for the MongoDB Java driver, but I've left the category as "Unspecified" because it could apply to any driver download for which the official sites say to "Just use Maven/etc"

    Right now the documentation for the MongoDB Java driver (https://mongodb.github.io/mongo-java-driver/4.2/driver/getting-started/installation/) indicates that "The recommended way to get started using one of the drivers in your project is with a dependency management system." However, as far as I could tell from my own research, the official MongoDB sites have no official direct download link for the driver/dependency jar files - only the Maven groupId/artifactId are provided. If for some reason a developer is restricted such that they cannot use a dependency manager for their project and must obtain the jar files as a direct download, they must find the official Apache Maven repository on their own, and download the files from there.

    I understand that this seems like a problem that can be solved by saying "just suck it up and use Maven", but please understand that at its core, this actually constitutes a security issue, as it makes it difficult for developers to find a download that they know they can trust.

    Consider the following situation: Due to some situation, a developer is unable to use a dependency manager for their project. They must use a direct download of the driver/dependency jar files for the MongoDB Java driver in order to do their job. The first thing they will likely do (rightfully so) is go to the official MongoDB sites to try and find a download. They will not find it, and will instead look elsewhere.

    Performing a Google search for "mongodb java driver" returns first the official MongoDB sites, which the developer already knows will not help them, and then returns an unofficial Maven Repository browser (mvnrepository). I haven't looked into the validity of this site, and I'm usually one to assume the best of intentions, but the fact remains that it's run by a person who is not affiliated with Apache/Maven or MongoDB, from which the developer will likely download several unverified jar files and include them with their project. This is a big security risk, as theoretically speaking, for all we know this site could be malicious, but it remains the most convenient option for the developer, because the official MongoDB sites do not include one. The safest option for the developer is to use the official Maven repository at search.maven.org, but this site only appears at the very bottom of the first page of the Google results, and the developer may not even see this during their search.

    I feel like this problem could be fully solved by creating a section on the "Downloads" page (https://www.mongodb.com/try/download) for drivers, and including the most recent normally-supported release of each driver, including its dependencies. This may not be the recommended method, and it could very well include prominent text encouraging developers to consider using a dependency manager if possible, but it would effectively remove the potential for developers to accidentally download a malicious jar file from an unverified source and include it with their project.

    TL;DR: If you don't include a direct downloads for MongoDB drivers/dependencies, a malicious actor on the internet will.

17. Nearest read preference should take account of database load

    I understand it only take account of network latency however this node can have high load and would give a poor response. Instead, I wished the driver would contact the more distant network latency node that has less CPU/memory load.

19. BsonIgnoreIfEmpty - Property Attribute

    Like BsonIgnoreIfDefault and BsonIgnoreIfNull, we can add BsonIgnoreIfEmpty.
    It can be added on IEnumerables (which we basically know they cannot have infinite values since it is inserted to db after all..) and if the IEnumerable is empty, it wont serialize it to the db BUT will know to put default value (an empty list for example) in said property.

    They will decrease below boilerplate code for IEnumerable<T>:

    Serialization:
    Field = otherField?.count > 0 ? otherFIeld : null;

    Deserialization:
    otherField = Field ?? new List<T>;

    Obviously, we can improve this code to also support Dictionary<Tkey, Tvalue>.
