Contributed to the MariaDB/server repository by developing a read-only system variable, init_rpl_role, which exposes the server’s replication role at runtime. This feature was implemented in C++ with a focus on database management and system variables management, allowing users to access replication role information without requiring a server restart or impacting normal operations. The approach ensured backward compatibility and non-intrusive integration, validated through standard SQL queries such as SHOW GLOBAL VARIABLES and SELECT statements. The work enhanced operational observability and troubleshooting capabilities, with the implementation linked to a specific commit and subjected to code review and testing for reliability.
