1. Introduction to Replication and Sharding in MongoDB.
2. Configuring Replica Sets.
3. Failover and Recovery with Replication.
4. Horizontal Scaling using Sharding.
5. Shard Keys and Balancing Data Across Shards.

File you will be working on: src\content\docs\mongodb\replication-and-sharding.mdx

🎯 Expected Outcome

The expected outcome is to add a comprehensive section under MongoDB that covers the following topics:

• Introduction to Replication and Sharding: Overview of what replication and sharding are, and why they are important for scaling and ensuring high availability in MongoDB.

• Failover and Recovery with Replication: Explanation of how MongoDB handles failover and data recovery through replication.
• Horizontal Scaling using Sharding: A guide on how sharding enables horizontal scaling in MongoDB, including its architecture.
• Shard Keys and Balancing Data: Best practices for choosing shard keys and managing balanced distribution of data across shards.

The content should include practical examples using MongoDB commands and configurations, showing real-world use cases for replication and sharding in production environments.
