Query Optimization

Your slowest queries, fixed.

AI-driven tuning that ranks every query by business impact, proposes precise rewrites, and simulates the fix before it ships.

What it is

The 10× queries you didn't know were possible.

An AI query advisor that analyzes your top workloads, explains why each plan is suboptimal, and proposes the specific rewrite, index, or schema change that will improve it — with quantified predicted impact.

Why it matters

The hard part isn't the model — it's the workflow.

Most query tuning guides point at the biggest offenders. We go further: we tell you the fix, prove it on a replica, estimate the runtime cost and migration risk, and hand the engineer a PR that's ready to review.

What's included

Top-N query ranking weighted by business impact
Plan-aware rewrite suggestions (joins, subqueries, CTEs)
Missing and redundant index detection
Composite and covering index recommendations
Schema-level recommendations: partitioning, denormalization
Shadow-run validation with traffic replay

Real-world scenarios

How enterprises deploy this service to solve specific, high-stakes problems.

High-frequency trading

Trading platform shaved 72% off matched-order latency

The optimizer proposed a covering index on a three-column lookup that the team had missed for two years. Shadow validation against replayed market-open traffic confirmed a 72% p99 reduction before rollout.

B2B analytics

Analytics vendor cut p95 dashboard load time from 18s to 2.4s

Rewriting 4 tenant-facing aggregations and adding 2 partitioned indexes delivered a 7.5× improvement on the heaviest workload, with zero schema downtime.

Gaming

Mobile gaming company eliminated a seasonal lobby-join slowdown

The advisor flagged a CTE pattern that was forcing full table scans at peak hours. A join rewrite + one composite index held p99 under 40ms through the holiday event.

How it works

1

Analyze

Continuously scan live workload for high-impact optimization candidates.

2

Propose

Generate concrete fixes with predicted speedup and migration cost.

3

Validate

Shadow-run against replayed production traffic on a replica.

4

Ship

Hand the engineer a reviewable PR with rollback plan.

Why VS Tech

Fix, not report

Every recommendation comes as a reviewable diff, not a bullet point.

Risk-priced

We estimate migration cost, lock duration, and blast radius up front.

Replay-validated

Every fix is proven on replayed traffic before a human sees it.
