This project implements a Write-Ahead Log (WAL) in Go, using Protocol Buffers (default) as the encoding format for all log records. The goal of this WAL is to provide a reliable foundation for systems that require strong durability guarantees and predictable recovery behavior. The WAL records every change in a strictly sequential order and ensures that each entry is written to stable storage before it is considered committed. By using Protocol Buffers, each record is encoded in a compact and schema-safe format, which makes the log easy to extend and efficient to store.
