ClickHouse workshop guide for hands-on learning

A ClickHouse workshop provides developers with practical experience in schema design, data ingestion, queries, and pre-aggregation, preparing them for real-world analytics projects using this column-oriented SQL database tailored for OLAP workloads. The half-day session consists of five modules, each with specific exercises that utilize standard ClickHouse SQL and can be executed on a local ClickHouse instance, ClickHouse Cloud, or Tinybird's managed environment. Participants are expected to have prior SQL experience and can optionally use sample NDJSON event files for ingestion exercises. Key skills developed include designing a MergeTree table with appropriate partition and sort keys, ingesting events via batch processes and Kafka for production, writing optimized aggregation queries with PREWHERE and sampling, building and querying materialized views, and applying TTL for data lifecycle management. The workshop also discusses transitioning from this learning environment to production settings, emphasizing the need for ingestion pipelines, monitoring, and API layers, with Tinybird offering a managed solution that integrates these components and facilitates a smoother setup and execution process.
