AgileData.io - DataOps: Enhanced Database Connection Stability

We've fine-tuned our database connection handling to improve reliability, especially during high-traffic periods and cold starts.

**What Changed:**

* Disabled Spanner metrics thread that was causing SSL errors during Cloud Run cold starts
* Optimized session pool configuration for better performance
* Improved session caching strategy for handling multiple simultaneous instances
* Enhanced retry logic for SSL connection issues

**Technical Details:**

* Set SPANNER_ENABLE_BUILTIN_METRICS_EXPORT to false to prevent conflicts
* Configured session pool size for optimal performance
* Implemented more effective session caching for cold start scenarios
* Added retry mechanisms for transient SSL issues

**What This Means for You:**

* More stable connections during peak usage times
* Faster response times when the platform scales up to handle load
* Reduced timeout errors and connection issues
* Smoother overall platform performance

This optimization work ensures the platform remains responsive and reliable even as usage grows.
