May 1, 2025Monthly summary for 2025-05 (percona/percona-server-mongodb): Key features delivered include (1) Authentication Restrictions for Load-Balanced Connections (Proxy Protocol): added configurable restriction modes (origin IP or peer IP) with tests validating behavior and startup parameter documentation for clientSourceAuthenticationRestrictionMode. (2) Increased FLE2 per-field tag limit for Indexed Text Encrypted Values: raised the serialization tag limit from 8-bit to 32-bit with tests updated to support more text search tokens. No major bugs fixed this month. Overall impact: strengthened security for load-balanced deployments behind proxy protocols and expanded FLE2 text search capabilities, enabling broader compliance and performance. Technologies/skills demonstrated: C++ code changes in MongoDB server, test automation and validation, documentation updates, and cross-team collaboration tracked via SERVER tickets.
