Independent DBA lab
Databases that don’t panic under load.
NorthGridLab focuses on database performance, reliability, and observability. When queries go rogue and I/O starts screaming, we step in, dissect, and bring order back.
Reliability
Backups, HA/DR, failover strategies.
Observability
Monitoring, metrics, anomaly detection.
About
A small lab that speaks fluent execution plan.
NorthGridLab is an independent DBA-focused studio. The mission is simple: make databases predictable. No magic, no cargo cult tuning, just deep analysis and practical fixes that survive production.
Services
Query & Execution Plan Analysis
Most performance issues are not about hardware. They are about bad decisions made by the optimizer under imperfect statistics. We read execution plans like forensic reports: where rows explode, where estimates lie, where memory grants go rogue. Then we fix the root cause, not the symptom.
Performance Audits
When a system slows down, the problem is rarely where people look first. We analyze waits, IO patterns, CPU pressure, and query behavior together. The goal is to map the real bottleneck, not just chase high CPU graphs.
Backup & Restore Validation
A backup that was never restored is just a comforting illusion. We verify chains, test restores, and make sure your RTO/RPO are not theoretical. When things break, recovery must be boring and predictable.
HA / DR Architecture
AlwaysOn, Patroni, and replication setups all look good on diagrams. Reality is different. We design failover strategies that actually work under stress, including edge cases nobody tests until production forces them to.
Monitoring & Observability
Metrics without context are noise. We build monitoring that explains what is happening: from PLE drops to replication lag spikes. The system should tell a story before it fails.
Emergency Troubleshooting
When everything is on fire, there is no time for theory. We prioritize fast signal extraction: top queries, blocking chains, IO stalls. Stabilize first, optimize second, sleep later.
