Start with Apache Iceberg. --- Learn # Interactive lessons on the things worth understanding deeply. Short, hands-on explainers on data engineering, platforms, and leadership. Each lesson lets you poke at the moving parts - diagrams you can open, simulations you can run, and a quick check at the end - because some ideas only click when you can play with them. New here? Start with **Apache Iceberg**, then **Lakehouse table formats** to build your data-engineering foundation - then branch into the Applied AI track (vector search, RAG, ClickHouse) or the Leadership track at whatever order suits you. [Available Data engineering ### Apache Iceberg, explained interactively Explore the metadata tree, simulate writes and time-travel, evolve schema and partitions, and test yourself. Beginner to advanced ~25 min 4 interactives](apache-iceberg.html) [Available Data engineering ### ClickHouse, explained interactively Columnar storage, the MergeTree sparse index, parts and merges, table engines, and writing efficient queries. Beginner to advanced ~30 min 5 interactives](clickhouse.html) [Available Data engineering ### Advanced ClickHouse, explained interactively Compression and codecs, materialized views, projections and skipping indexes, and SharedMergeTree cloud scaling - the advanced layer, made interactive. Intermediate to advanced ~30 min 5 interactives](clickhouse-advanced.html) [Available Applied AI ### Vector search, embeddings & RAG Explore an embedding space, watch approximate nearest-neighbour search, and simulate a RAG pipeline end to end. Intermediate ~25 min 4 interactives](vector-search-rag.html) [Available Platform strategy ### Lakehouse table formats compared Iceberg, Delta, Hudi, and Paimon - what actually differs, and how to choose for your workload. Intermediate ~20 min 4 interactives](lakehouse-table-formats.html) [Available Leadership ### Leading data teams that compound Operating models, prioritisation, and the habits that turn a busy data team into a high-leverage one. For leads ~18 min 3 interactives](leading-data-teams.html)
