Alok Pandey enhanced the percona/pmm repository by implementing a security-hardening feature focused on RDS performance_schema access. He adjusted PMM user privileges to enforce the principle of least privilege, removing unnecessary write permissions and ensuring only SELECT access was granted. This change reduced the risk of unintended writes and improved security compliance for database administration. Alok updated the project’s documentation in Markdown to clearly outline the new access requirements, supporting better governance and transparency. His work demonstrated a strong understanding of security best practices and database administration, delivering a targeted solution that improved the overall risk posture of the system.
