String Json Parser
lately, I imported a big CSV file, containing fields with values of Json object in String format, the simplest way to parse those strings to object it was by doing find().forEach( JSON.pase then update) it taken too much time to update the collection the only think that i have could done to reduce the latency is putting write priority to 0 which isn't very advisable with high throughput of updates, I don't really know for sure I'am not the expert here but working with big data demand a lot of cleaning, and not being able to do the cleaning on…

Extend db.collection.distinct() to work with multiple fields in a compound key
Currently the distinct() command finds the unique set of values for a SINGLE specified field across a collection or view. For example:
db.staff.distinct("last_name" )If there is an index on the lastname field, the DISTINCTSCAN plan can use that index and the operation is very fast.
To find the unique values for a set of more than one fields, the $group aggregation stage has to be used like this:
db.staff.aggregate([
{$group: {id: {FName: "$firstname", LName: "$last_name"}} ]);This operation does not really need the $group functionality, as it is not calculating a sum/min/max/average/etc value using the…

Allow collection collation to be editable
Collation of a collection can be set at creation time only. It would be useful to edit these fields to avoid creating an entire new collection and copying the collection over.

Reduce the minimum value for watchdogPeriodSeconds
The storage watchdog attempts to create, write, and read a test file in critical directories every 10 seconds.
The watchdogPeriodSeconds parameter controls how often these a thread checks to ensure at least one check has succeeded since the last check.
The minimum value for watchdogPeriodSeconds is 60 seconds. This means that in the worst case, the mongod could be unable to write for up to 2 minutes before the watchdog asserts and kills the stalled node. That is a very long time for a primary node to be stalled in a busy cluster.
It does make sense that watchdogPeriodSeconds must…

wiredTiger open files usage
Currently WT uses a file per collection and index, leading in some scenarios to extremely high number of open files/dhandles.
Is there any plan to support one file/dhandle per database?

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.

Allow multiple text indexes per collection
MongoDb only allow one text index by collection, in contrast of other index types.
This is a limitation that makes it difficult to develop projects with search functionality, for example, if you want to add a text search for advanced users on all fields and a public search on a subset of fields, there isn't a simple and performant way to solve it.
Many developers end up using other products like elastic search, or creating additional collections and using lookup, or using preg_reg or building smart indexes when the creation of multiple text indexes per collection would allow a quick,…

Ability to enable collection name enforcement
Currently if you perform a find or other operation, and you have a typo in your collection name, the operation will execute successfully and there is no indication that the collection you are operating on doesn't exist. It would be handy if there were some sort of session variable that could be set that tells the engine, to return an error if the collection being operated on does not exist. For example, lets say we have a collection named "myCollection". If I issue a find with a typo in the collection name from the shell like:
db.myCollectio.find();
This will successfully…

Ability to view and track collection wise transactions (read,write,success,failures)
We have multiple microservices using the same collection and we'd like to track how many calls come from each, and also understand which transactions are successful or not.
Ultimately this will allow us to understand the MDB usage by each of the microservices.
[setting verbose logging level to 1 and then using these logs to create a dashboard in Splunk doesn't give us enough granularity]1 vote -
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 -
Find all geoJSON points within a large collection of polygons. Reference collection in geoWithin.
I would like to be able to find all geoJSON points located within a collection of polygons. My personal goal is to find points located within earth's water bodies. The water bodies are located in their own collection while the geoJSON points are located in a separate collection within the same DB. Mongo's geoWithin function only lets me hard code the polygons, but I would like to reference a collection of polygons.

Auditing requirement for the changes done through Ops Manager portal
Changes done through Ops Manager portal are visible only in Alerts(Activity Feeds). Though these Alerts(Activity Feeds) can be derived through API, our auditors may not accept API calls and we need ops manger to log these change in respective deployment mongo audit.log

Kafka audit event streaming
Provide Kafka Topic as a write target for database auditing and database message logging.
https://docs.mongodb.com/manual/core/auditing/
Auditing is currently limited to a local and editable JSON/BSON file or the system console log.
The SYSLOG is not recommended by MongoDB. "The syslog message limit can result in the truncation of the audit messages. The auditing system will neither detect the truncation nor error upon its occurrence."5 votes
