Expand description
Write-Ahead Log (WAL) module that provides interfaces for durable logging.
The WAL is a critical component for maintaining data consistency and durability in distributed systems. It ensures that all state changes are first recorded persistently before being applied, enabling:
- Crash recovery: System can recover its state by replaying the log
- Consistency: Ordered record of all state transitions
- Durability: Persistent storage of operations
This module defines the core WAL trait that implementations must satisfy.
