- Improved the `getRaftLogIndex` method to accurately report the Raft log index by incorporating fallback logic to read persisted snapshot metadata when the RQLite status is unavailable or returns zero.
- Added a new method `getPersistedRaftLogIndex` to read the highest Raft log index from snapshot metadata files, ensuring accurate reporting even before RQLite starts.
- Centralized the data directory path resolution logic in `rqliteDataDirPath`, simplifying the codebase and enhancing maintainability.
- Added structured logging for RQLite components, including cluster discovery and leadership processes.
- Introduced methods for preparing the data directory and launching the RQLite process, improving code organization.
- Implemented exponential backoff for leadership checks to reduce log noise and improve reliability.
- Enhanced peer health tracking and membership update logic to streamline cluster synchronization and recovery.
- Added ClusterDiscoveryService to manage peer discovery and synchronization for RQLite nodes.
- Introduced new configuration options for cluster synchronization intervals, peer inactivity limits, and minimum cluster size.
- Enhanced validation logic to ensure proper configuration of cluster parameters.
- Implemented metrics collection for cluster health and peer status, improving monitoring capabilities.
- Updated RQLiteManager to integrate with the new discovery service, allowing for dynamic leadership and cluster joining logic.
