Why is it necessary to configure tiers correctly in MongoDB Atlas?

Configuring tiers correctly in MongoDB Atlas is essential to access advanced features such as Performance Advisor. MongoDB Atlas offers various performance-related tools and features that can greatly assist in monitoring and optimizing database operations. By selecting the appropriate tier, users can unlock capabilities tailored to their specific workload needs, including automated scaling, performance analytics, and suggestions for query optimization provided by the Performance Advisor.

These advanced features depend on the tier selected, as they are designed to help users manage resources more efficiently based on their application's demands. Without the right tier, users may not be able to benefit from these tools, leading to potential performance bottlenecks and inefficient resource management. Thus, selecting the correct tier is not just about performance; it's about gaining access to features that can drive better overall system performance and health.

The optimization of query speed, maintenance of data integrity, and minimization of data redundancy, while important, are aspects that focus more on database design and operational strategies rather than tier configuration specifically.
