$dateDiff operator should be useful to calculate age

In the documentation it says: " For example, two dates that are 18 months apart would return 1 year difference instead of 1.5 years.". But if startDate is 2021-08-01 and endDate is 2023-02-01, the result is 2 years difference. I think it should be...

Currently you can supply a `hint` to the `aggregation` call in order to tell MongoDB to use a specific index for the initial `$match`. But there is currently no way to specify which index to use for a `$graphLookup` later in the pipeline. I would...

Asynchronous variant of IIdGenerator

We have use cases where IDs assigned to documents are generated by an external service. Communication with the external service is asynchronous. We have created custom IIdGenerator implementations for this purpose, and they work, but unfortunately...

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...
