With Rapydo:
You would immediately see:

• Which queries are taking the longest to execute
• Whether these queries are using indexes effectively
• If the buffer pool is being utilized optimally
• Recommendations on how to optimize the problematic queries

This level of detail allows you to address the root cause of performance issues quickly and effectively.

Customization and User-Defined Rules

CloudWatch Customization

CloudWatch does offer some customization options:

• Setting alarms based on metric thresholds
• Creating custom dashboards
• Combining multiple metrics in a single graph

However, these customizations are generic and lack MySQL-specific intelligence. For example, you can set an alert for high CPU usage, but CloudWatch won't provide context on why the CPU usage is high or how to address it in the context of MySQL operations.

Rapydo's Advanced Customization

Rapydo takes customization to the next level with user-defined rules tailored specifically for MySQL environments:

• Intelligent Alerting: Create alerts based on MySQL-specific metrics like query execution time, table scan rates, or index usage.
• Automated Performance Adjustments: Set up rules to automatically optimize your database when certain conditions are met. For example:
  • Automatically adding indexes when query performance degrades
  • Adjusting buffer pool size based on usage patterns
  • Identifying and optimizing frequently executed slow queries
• Custom Optimization Workflows: Design workflows that combine multiple optimization steps based on your specific use case and performance requirements.

‍

Alert Example

Automation Example

Suppose you frequently face issues with slow queries. With Rapydo, you could set up a rule like this:

IF average_query_execution_time > 1 second

AND query_frequency > 100 per minute

THEN

    1. Analyze query execution plan

    2. Suggest index optimizations

    3. If approved, automatically apply optimizations

    4. Monitor query performance for next 1 hour

    5. If performance improves, keep changes; else, revert

This level of automation and MySQL-specific intelligence is simply not possible with CloudWatch alone.
