A write-ahead log is not a universal part of durability

Read Original

This technical article argues that a write-ahead log (WAL) is not strictly required for database durability, though it is standard practice. It explains durability concepts, contrasts an in-memory database with a basic disk-persisted version, and discusses crash safety and fsync to build foundational understanding of why WALs are critical in modern database design.
