- Guidance on storage tiers and temp usage
Decision clarity
Leaders see trade-offs with side-by-side KPIs.
- Throughput, p95/p99, WAL volume, temp spills, cache hit
- Clear rationale and expected impact per change
- Evidence for approvals and change boards
Safer rollouts
Adoption plans that confine risk to agreed windows.
- Replay-driven validation where needed
- Staged rollout with rollback paths
- Runbooks that ops can trust
Solution offerings
Pick the path that fits your timeline
Rapid Essentials for quick wins, Replay-driven for empirical certainty.
PostgreSQL Tuning - Essentials
3–5 days
- Config & workload review: instance/storage profile, extensions, connection patterns, OLTP/OLAP mix
- Right-sized configuration: memory, caching, concurrency, WAL to smooth p95/p99 and avoid over-provisioning
- Plan stability: improve cardinality awareness and reduce plan regressions
- Lean storage & indexes: bloat reduction, remove wasteful structures, add only high-ROI indexes
- Hotspot remediation: reduce temp spills, raise cache effectiveness, prevent saturation under load
Deliverables: Tuning Sheet (values + rationale + expected impact), quick-wins runbook, results read-out.
PostgreSQL Tuning - Replay-driven
2–3 weeks
- Snapshot & staging: consistent snapshot, optional anonymization; prod-comparable staging
- Targeted telemetry: time-boxed, high-signal logging for replay analysis
- Workload capture & replay: preserve concurrency and think-time patterns on an isolated copy
- Automated experiments: sweep memory, planner, parallelism, logging, background maintenance
- Scorecard & selection: side-by-side runs (throughput, p95/p99, WAL, temp, cache hit) with rollout plan
Deliverables: Full parameter-sweep report, diff vs. baseline, scripts/IaC snippets, 90–120 min read-out.
How it works
Evidence before change, guardrails for rollout
A low-friction process that gives quick wins fast, and replay-driven certainty when you need it.
We tune for your real workloads, not synthetic tests. When replay is needed, we capture and preserve concurrency and think-time patterns so the improvements hold in production. Every change ships with rationale, expected impact, and rollback guidance.
1
Baseline & scope
Understand goals, constraints, and the instance(s) in scope.
- Collect workload shape, connection patterns, extensions
- Align on p95/p99 targets and cost goals
- Decide Essentials vs. Replay-driven path
2
Measure & prioritize
High-signal telemetry to find the biggest wins first.
- Enable low-overhead metrics and logging; revert cleanly
- Identify hotspots: temp spills, cache hit, bloat, plan drift
- Prioritize changes by impact, effort, and risk
3
Tune & validate
Apply changes and validate outcomes.
- Essentials: rapid tuning sheet + quick-win runbook
- Replay-driven: capture → replay → sweep parameters
- Side-by-side KPIs for leadership and change boards
4
Rollout & guardrails
Make adoption safe and predictable.
- Staged rollout with rollback and checkpoints
- Runbooks and IaC snippets for reuse
- Verification plan to lock in gains
