1. Tinybird's ClickHouse® Course: Free Developer-Focused Training
What the Course Is and Why It Exists
Tinybird's course page presents a free course aimed at developers to learn how to work with ClickHouse® from fundamentals to typical production patterns and decisions. The promise is clear: help you understand how product and data teams at companies like Vercel and Canva query billions of rows with very low latencies, but without stopping at "hello world."
The focus isn't on memorizing syntax, but on internalizing the mental model: how data is physically organized, why schema design rules performance, how to prevent ingestion from becoming the bottleneck, and which pieces typically break when you scale. The site indicates they share over three hours of video content, with 40+ tutorials and 70+ lessons spread across 6 modules.
Overall Structure: 6 Modules with Logical Progression
The FAQ summarizes the progression well: you start with foundations (architecture, schema, engines), then move to ingestion, and from there, query optimization, schema evolution, distributed architecture, and practice with real cases. Starting from the ingestion module, they introduce Tinybird in examples, but the course emphasizes that it's not required to follow the curriculum.
Module 1: Foundation (Real Foundations)
This covers what you need to avoid designing ClickHouse® "as if it were Postgres": architecture, schema design principles, and storage engines. The module page lists reasonable prerequisites (SQL, some command line knowledge, and familiarity with distributed systems concepts, though not mandatory).
The table of contents shows lessons on columnar databases, "internals", table design, data type rules, codecs, and why data locality matters. There's also a deep dive into engines and especially the MergeTree family (including variants like ReplacingMergeTree and AggregatingMergeTree).
Module 2: Ingestion (Ingestion and Scaling)
This module gets practical: ingestion types (batch vs streaming), typical problems when scaling writes, the "ingestion proxy pattern", and practical connectors (HTTP, Kafka, cloud storage), plus backfilling, snapshots, and the APPEND vs REPLACE distinction. It also covers real-time change data capture patterns.
An operational detail: content in this and other modules is "unlockable" by providing your email, which the site explicitly states.
Module 3: Querying and Optimization (Production-Grade Speed)
The core of this module: materialized views for pre-aggregation, optimization strategies, sorting keys and index granularity, EXPLAIN, data skipping indices, PREWHERE, JOIN optimization, and dictionaries. In other words, what separates a dashboard that flies from one that collapses under concurrency.
It includes practical comparisons like Projections vs Materialized Views and detailed guides for writing efficient queries.
Module 4: Schema Evolution (Migrations Without Tears)
Few courses explain this well, but here it gets an entire module: why schema evolution is hard, what primitives the engine offers, how to classify changes by operational cost (from metadata updates to mutations and rewrites), and safe migration patterns. It closes with a real multi-tenant example—typically the point where many teams hit a wall.
Module 5: Distributed Architecture (Clusters and Operational Reality)
This module dives into shards, replicas, parts, partitions, merges, and indexes; along with scaling strategies (reads and ingestion) and operational challenges. It's important because ClickHouse® doesn't "scale automatically by magic"—performance depends on partitioning decisions, sorting choices, and how you manage the lifecycle of parts and merges.
Module 6: Practice What You Learned (Cases and Templates)
Here the course moves from theory to practice: case studies (web analytics, log analytics, and user-facing analytics) and a "Build Your Own" section with project ideas like OpenTelemetry, logs explorer, LLM tracker, Ghost CMS, URL shortener, or "Inbox Zero"—designed to help you practice building a complete data product from start to finish.
Why It's Useful If You Already "Know SQL"
If you come from row-based databases, ClickHouse® forces a mental shift: in analytics, what matters is reading fewer bytes, leveraging columnar storage, and designing for repeated filters and aggregations. The course emphasizes this from the beginning and chains together topics that, in scattered documentation, often remain disconnected.
For example:
- The MergeTree family is the heart of storage and brings concepts like partitioning, indexes (including data-skipping), and internal mechanics that directly affect latency and cost.
- Materialized views (and their relationship to projections) are a huge lever for moving computation from "query time" to "insert time" and maintaining low P95s in real analytics.
- Understanding parts, merges, and how they grow or compact explains 80% of production surprises when ingestion spikes or when you change the schema.
Cost, Requirements, and Fine Print (Matters)
According to the site, the course is free—no credit card, no hidden costs, no upsells. To get started, they ask for an email and warn you'll be subscribed to a bi-weekly newsletter (you can unsubscribe). They also indicate you don't need to install anything or prepare a specific instance: you can follow along with any ClickHouse®, including Tinybird's free tier if you want hands-on practice.
In parallel, they clarify the difference between ClickHouse® (open source technology) and ClickHouse®, Inc., noting that Tinybird is not affiliated with or sponsored by that company, along with the trademark notice.
How to Get the Most Out of It (Without Wasting Time)
Take the Foundation module slowly and apply what you learn to a small but real dataset. If you don't leave with a clear intuition about "sorting keys, partitions, and types," everything else becomes trial and error.
In Ingestion, focus on the patterns and decision order: event format, idempotency, backfilling, and how to prevent writes from sinking the cluster.
In Optimization, practice with a slow query and make it fast using a materialized view or changing sorting and filters (PREWHERE, indexes, etc.). That's where things "click."
If you work with multi-tenant systems, don't skip the migration example in the Schema Evolution module. It's a common problem and expensive to fix late.
To consolidate, pick a case from the Practice module (web analytics or logs) and turn it into a mini product: ingestion, model, aggregates, endpoints, or typical queries.
