1,000+ QPS customer-facing dashboards, monetised at 50%+ lower TCO

A high-growth B2B fintech with 18,000+ merchants turned petabytes of transaction data into a premium self-service analytics product, priced on performance it could finally afford.

THE STORY

From cost center to premium feature

The dashboards are now sold to merchants as a premium offering, priced on performance the old stack could not deliver at any budget.

01

The opportunity

Petabytes of transaction data across 18,000+ merchants, and a plan to sell self-service analytics on top of it. The catch: every query had to meet strict latency SLAs at high concurrency, or the product was dead on arrival.

02

The wall

Approaching 1,000 QPS, the incumbent engine could not hold p95 under 2 seconds. Scaling capacity ballooned infrastructure cost while performance still lagged: high concurrency and low latency, but never both.

03

The evaluation

A structured proof of concept on their own data: candidate engines were scored on the criteria that decided the product - p95 latency under real concurrency, cost at scale, security, and ease of adoption - with production queries replayed rather than synthetic benchmarks.

04

The drop-in

e6data ran the pilot alongside the existing engines, on the same S3 tables and Glue catalog. Granular autoscaling absorbed traffic bursts and scaled back down, and near-real-time querying kept merchant insights fresh.

05

The result

12x faster query completion across OLAP and near-real-time workloads, 1,000+ QPS sustained with p95 under 2 seconds, and 50%+ lower TCO. The analytics product shipped as a new revenue stream instead of a write-off.
