Data and ClickHouse area

Queries cost more

than the data.

eBay rebuilt its OLAP platform on ClickHouse and cut over 90% of its Druid infrastructure. ClickHouse is the engine under Langfuse, Helicone, SigNoz and HyperDX. We design it, migrate to it and keep it running, with certified consultants.

Why ClickHouse

The engine under the platforms you know

This isn't a technology bet: it's the database behind Cloudflare's analytics, Uber's logging and eBay's OLAP. And now Langfuse, Helicone, SigNoz and HyperDX too.

  1. Diagnosis

    2 weeks

    Free

    Data platform X-ray

    Cost per query and per terabyte today, bottlenecks, and the estimated saving of a ClickHouse migration — before you commit a euro.

  2. Pilot Build

    2-3 weeks

    First workload on ClickHouse

    One real dataset moved onto ClickHouse and compared against your current platform on the same queries. Real numbers, not brochure benchmarks.

  3. Build

    8-12 weeks

    ClickHouse migration

    Moving off Elastic, Druid, Snowflake or BigQuery: data model, ingestion, schema and go-live, without stopping what's running.

  4. Stewardship

    Retainer

    Platform stewardship

    Continuous tuning, cost control and platform growth, with the people who built it.

What you get

A migration that doesn't stop what's running

The current system stays live throughout. One workload at a time, and every step can be stopped.

Real workload analysis

Which queries actually cost, which are slow, which nobody has run in months. Often the third group is the largest.

Data model and schema

Sort keys, partitioning and types chosen for your real access patterns: this is where ClickHouse either flies or crawls.

Ingestion and sync

Loading from existing systems with dual writes during the transition, so the comparison is like-for-like.

A measured comparison, not a promised one

The same queries on both systems, cost and latency side by side. If it doesn't pay off, we say so and you stop.

Go-live

Backups, replicas, monitoring and runbooks. A fast database nobody can operate is a problem postponed.

Handover

Your team learns to read query plans and tune on its own. Stewardship becomes a choice, not a dependency.

Questions we get

What people ask before signing

Not always, and not necessarily all of it. It shines on analytical queries over large volumes; for transactional workloads or governed reporting it can coexist with what you have. The Diagnosis says which part is worth moving.
