What happens during MongoDB replication failover?
During MongoDB replication failover, the primary node goes down, and one of the secondary nodes is elected as the new primary.
How does the election process work for the new primary?
The election process involves a voting mechanism where the secondaries communicate with each other to determine which node has the most up-to-date data.
What are the potential issues that can arise during this process?
Potential issues include split-brain scenarios, where two nodes believe they are primary, and data inconsistency if not properly managed.
How can I prevent these issues in my MongoDB setup?
You can prevent these issues by configuring proper write concerns, using replica set configurations, and monitoring your nodes regularly.
