mongodb

Scope

Covers MongoDB itself: document modelling and its migration path, CRUD and update operators, the aggregation pipeline, indexes and explain, transactions and durability, replication and sharding semantics, time-series collections, Atlas Search and vector search, driver-side connection and cursor behaviour, and authentication, authorisation and encryption at the database level.

The body is written against MongoDB 8.0 (the current LTS). Rules that need a rapid release carry a gate such as (8.3+); 8.3.x is the current rapid release and the version every measurement quoted below was taken on. Nothing here assumes 9.0, which is still in alpha.

Not covered:
