redb is an embedded key-value store and ACID-compliant storage engine. It functions as a persistent storage system for saving and retrieving data as key-value pairs within a tree structure.
The engine is built as an MVCC transactional database, utilizing multi-version concurrency control to manage simultaneous reads and writes without blocking. It employs a single-writer multi-reader model to ensure data consistency while allowing multiple threads to access the store.
The system provides persistent state management and atomic transaction management to prevent data corruption during crashes. It handles concurrent data access and ensures that groups of changes are applied as single units.
