During November 2024, Alex Harding developed an automated retention-based purge system for accounting tallies in the storj/storj repository. He designed and implemented a configurable retention policy, allowing administrators to specify how long tallies are kept before being deleted. This involved adding a Purge function to the tally service and introducing the DeleteTalliesBefore method in the database layer, ensuring efficient and reliable cleanup of outdated records. Working primarily with Go and leveraging his expertise in backend development and database management, Alex addressed compliance and regulatory requirements by enabling periodic, automated data removal, laying a solid foundation for future system administration enhancements.
