Worked on enhancing the reliability and observability of Azure blob storage reads within the percona/percona-backup-mongodb repository. Developed a RetryReader in Go to address transient read errors, improving the resilience of backup and restore operations in cloud environments. Integrated custom logging to surface read failures, enabling faster diagnostics and reducing operational overhead related to storage issues. Focused on backend development and error handling, the work was delivered as a focused, single-commit change, minimizing risk and simplifying rollback. This update increased backup success rates and aligned with the product’s goals for reliability, observability, and compatibility with Azure cloud storage systems.
