I'm working on a project where I need to deploy two MongoDB databases in different geographical locations. I want both databases to work independently, allowing reads and writes on both sides. However, I also need a mechanism to ensure that changes made in one database are synced to the other in a master-master-like fashion.
What strategies or technologies can I employ to achieve this master-master replication setup in MongoDB? Are there any best practices or specific considerations for handling synchronization across different locations? I'd appreciate any insights, examples, or recommended tools to implement a robust and reliable solution for keeping two MongoDB databases in sync.
I've explored Active-passive, but it doesn't entirely fulfill my requirement for a master-master setup with databases deployed in different geographical locations. While primary-secondary replication is excellent for high availability and fault tolerance, it doesn't support simultaneous writes to both databases, making it fall short for my specific use case.
