May 2025 monthly summary focusing on delivering observability, packaging reliability, and deployment readiness across Percona products. Key telemetry groundwork was established for Percona XtraBackup (PXB) and its Docker images, enabling call-home data collection, versioning controls via environment variables, and a robust startup entrypoint for telemetry. Packaging and deployment improvements were completed for Percona MongoLink on Debian and RPM, including new packaging scripts and updated build pipelines to reflect service/name changes. A critical bug fix was implemented for mongosh, replacing the problematic cat command with fs.readFileSync to ensure reliable configuration parsing across multiple Percona Server MongoDB versions. Build resilience improvements were added for MongoLink packaging, with enhanced git clone error handling, Go module download retries, and module caching to reduce timeouts and failed fetches. These efforts collectively improve observability, deployment speed, and build reliability, delivering measurable business value and stronger quality signals to customers.
