Why Write-Ahead Logging Is Critical for Database Durability

Lucas and Luna dive into write-ahead logging (WAL), the mechanism that ensures your database can survive a power failure without losing data. They explain how PostgreSQL, Oracle, and SQL Server implement WAL, the performance trade-offs of synchronous vs asynchronous commit, and how checkpointing keeps the log from growing forever.
