How do you diagnose WiredTiger lock contention using diagnostic FTDC (Full Time Data Capture) metrics?
❓ Interview Prompt: Explain FTDC (Full Time Data Capture) diagnostic metrics, analyzing lock wait times, and resolving global write contention.
Analyzing FTDC diagnostic metrics and 'system.profile' reveals lock wait durations, queue depth, and global write lock contention bottlenecks.
Code Implementation Example
typescript
console.log('FTDC metrics reveal WiredTiger queue depth and lock wait durations');💡Diagnosing database lock contention using FTDC.
🎯 Interview Key Takeaway
Analyze FTDC diagnostic files to identify WiredTiger lock wait bottlenecks under heavy write concurrency.
