Write-ahead Log

Durable WAL with segment rotation, crash recovery and fsync guarantees

A write-ahead log that guarantees durability through segment-based rotation, CRC checksumming, and fsync — the same primitive that powers database engines and Kafka's log storage.

What it demonstrates

  • Durability guarantees
  • Segment rotation
  • Crash recovery
  • CRC checksums
