Multi-Source deployments with MongoDB Atlas Global Clusters
Source-replica replication

MapReduce

Eventual Consistency
Immediate Consistency
Session Consistency
Tunable Consistency

Eventual Consistency

Atomicity and isolation are supported for single operations

atomic operations within a document possible

Multi-document ACID Transactions with snapshot isolation

Concurrency

Yes - Synchronous writes to local disk combined with replication and asynchronous writes in parquet format to permanent shared storage

yes

optional, enabled by default

In-memory capabilities

Is there an option to define some or all structures to be held in-memory only.

yes

In-memory storage engine introduced with MongoDB version 3.2

User concepts

Access control

Access rights for users can be defined per object

Access rights for users can be defined per database

fine grained access rights according to SQL-standard
