Mini-LSM is a hands-on course for learning database internals by building an LSM-tree storage engine in Rust. It covers memtables, SSTs, compaction, crash recovery, MVCC, and transactions across a guided three-week curriculum plus a coding-agent track.

Use cases

• learn how LSM-tree storage engines work
• build a key-value storage engine in Rust
• understand compaction strategies and write amplification
• study crash recovery with write-ahead logs and manifests
• learn MVCC and transaction concurrency control
• prepare to read production storage engine code like RocksDB

When to choose

• you know basic Rust and want to understand what happens below database APIs
• you want a structured, hands-on course with tests and guided chapters
• you are a systems or backend engineer studying storage internals

When to avoid

• you need a production-ready storage engine for an application
• you want to learn SQL parsing, query optimization, replication, or distributed consensus
• you do not want to write Rust code
