pingcap/tidb

This system is a comprehensive database backup and restore toolkit designed for TiDB, encompassing the BR (Backup/Restore) and Lightning utilities. It provides robust capabilities for full, incremental, and point-in-time recovery, supporting diverse storage backends like S3, GCS, and EBS, while ensuring data integrity through checksums and encryption. The system also includes performance benchmarking tools and a suite of static analysis linters to enforce code quality and security standards across the codebase.

This period focused on integrating Dumpling and the BR tool into the TiDB codebase, establishing their standalone module structures and build systems. It involved extensive refactoring of BR and Dumpling components, alongside the addition of comprehensive integration tests to ensure reliability and compatibility across various storage backends and edge cases.

This period focused on restructuring the BR module by extracting distinct components like the import client, log client, and snapshot client into dedicated packages for better maintainability. It also introduced significant features for Point-in-Time Recovery, including checkpoint management, table filtering, and CRR progress tracking, alongside comprehensive integration tests to validate these new capabilities.
