Storage layer implementations
Provides file-based and RocksDB storage backends. Storage layer for d-engine.
This module provides pluggable and extensible storage components for persisting Raft state and application data. It defines core traits, adapters, and utilities to support different backend implementations.
Key responsibilities include:
- Managing Raft log entries and snapshots.
- Providing an abstraction layer (
StorageEngine) for persistence. - Supporting in-memory buffering and disk-backed storage (e.g., via Sled).
- Coordinating state machine application and snapshot lifecycle.
- Managing key expiration through lease-based lifecycle management.
This module is designed so developers can easily implement custom storage backends without changing the Raft protocol logic.
