Week 3: MongoDB Advanced Features and Optimization Techniques (Days 15-21)
In Week 3, we will dive deeper into MongoDB’s advanced features, focusing on performance optimization, replication, and security best practices. By the end of this week, you’ll be well-equipped to handle large-scale MongoDB projects with improved performance, high availability, and strong security.
Day 15: Performance Tuning in MongoDB
- Index Optimization:
- Review how to create efficient indexes to speed up queries. Understand which types of indexes (single-field, compound, and text indexes) work best for different queries.
- Using the
explain()Method: - Learn how to use
explain()to analyze query performance and identify slow queries. Use it to optimize your indexes and query patterns.
Example:
db.collection.find({ name: "John" }).explain("executionStats");- Sharding in MongoDB:
- Understand sharding and how it helps distribute data across multiple servers, improving performance and scalability for large datasets.
Day 16: MongoDB Replication
- What is Replication?
- Learn about MongoDB’s replication features, which allow data to be duplicated across multiple servers for high availability and fault tolerance.
- Setting up Replica Sets:
- Learn how to set up replica sets, where one node is the primary (write) node and others are secondary (read) nodes.
Example:
rs.initiate()- Read and Write Concerns:
- Learn about read and write concerns to ensure data consistency and reliability across replica sets.
Day 17: Data Consistency and Failover
- Consistency in Replica Sets:
- Learn how MongoDB handles data consistency across replicas and the importance of write and read concerns in ensuring consistency.
- Automatic Failover:
- Understand MongoDB’s automatic failover mechanism and how it ensures high availability by electing a new primary node in case the current primary fails.
Day 18: MongoDB Security Basics
- Authentication in MongoDB:
- Learn how to set up authentication in MongoDB to control access to the database using user accounts and roles.
- Authorization with Roles:
- Understand MongoDB’s role-based access control (RBAC) and how to assign specific permissions to users.
Example:
db.createUser({
user: "appUser",
pwd: "password",
roles: [{ role: "readWrite", db: "myDatabase" }]
});Day 19: Advanced MongoDB Security Practices
- Encrypting Data:
- Learn how to use MongoDB’s encryption features to protect sensitive data both in transit and at rest.
- Auditing and Monitoring:
- Explore MongoDB’s auditing and monitoring features to track database access and activities for compliance and security purposes.
- MongoDB Security Best Practices:
- Understand the best practices for securing MongoDB, including limiting access, using SSL/TLS, and implementing IP whitelisting.
Day 20: MongoDB Backup and Restoration
- Backup Strategies:
- Learn about MongoDB’s backup options, including the
mongodumptool and the Cloud Manager for automated backups.
Example:
mongodump --host localhost --port 27017 --out /backup/- Restoring Data:
- Understand how to restore data using
mongorestoreand how to handle full and incremental backups.
Example:
mongorestore /backup/Day 21: MongoDB Data Migration and Upgrades
- Migrating Data Between MongoDB Versions:
- Learn how to migrate data from one MongoDB version to another using tools like
mongodumpandmongorestore. - Upgrading MongoDB:
- Understand how to upgrade your MongoDB server and ensure compatibility with the latest version while maintaining data integrity.
Conclusion
Week 3 focuses on optimizing your MongoDB performance, ensuring high availability with replication, securing your databases, and managing backups and upgrades. Mastering these advanced features will enable you to handle enterprise-level MongoDB deployments efficiently.
In the next week, we will cover MongoDB’s advanced use cases, including working with large datasets and creating production-grade MongoDB applications. Stay tuned for Week 4, where we’ll take MongoDB to the next level!
