Strengths

When real-time analytics on large event data demands query speed and engineering exists.

Limits

When a managed warehouse is enough; BigQuery or Snowflake need less maintenance.

In depth

  • extreme query performance
  • open source, EU self-hostable
  • ideal for real-time and event data
  • SQL dialect with quirks

What is ClickHouse?

Blazing fast columnar database for real-time analytics. Open-source, self-hostable in the EU. We integrate it cleanly into your data architecture and draw a clear boundary to the alternatives.

When it fits, and when it doesn't

A fit when:

  • real-time analytics on large event data matters
  • self-hosting in the EU is wanted
  • a data-engineering team is in place

Less so when:

  • a classic BI warehouse is enough (then BigQuery)
  • no engineering resources are available
  • standard SQL without quirks is mandatory

What Datascale builds with ClickHouse

We decide the architecture, then build:

  • self-hosted setup in the EU region
  • schema design for event and real-time data
  • ingestion pipeline
  • connection to BI (Metabase, Grafana)
  • performance tuning and monitoring

The full picture lives in the matching service. We integrate and implement ClickHouse where it's the best fit for your case, not as an end in itself. Related: Audit Sprint.
