Personal learning notebook
Beautiful, self-contained lessons built one tangible win at a time. Each topic is its own course.
Relevance, internals, performance, Query DSL — depth for interviews.
The single-threaded model, data structures, caching, persistence & clustering — first-principles depth.
The clustered index, query planning, transactions, locking, durability & replication — first-principles depth.
The heap & MVCC, VACUUM & bloat, the planner, snapshot isolation, the WAL & replication — first-principles depth, taught by contrast with InnoDB.
The document model, WiredTiger storage, indexing, the aggregation pipeline, replica sets & sharding — first-principles depth, taught by contrast with Postgres/InnoDB.
Built with the /teach workflow.
