April 2026 performance summary for deepflowio/deepflow: Delivered two business-value capabilities with improved cross-VPC operability and enhanced observability. Reduced configuration friction, increased deployment flexibility, and strengthened troubleshooting capabilities. Aligns with our focus on scalability, reliability, and developer productivity. In particular, two key capabilities were implemented: - Global VPC Matching for Custom Services: Custom services can operate without a specified VPC ID by applying a global VPC match when no VPC IDs are provided; this included updates to the service data structure and tests to support the new behavior. Commit: 76de14a408280bcba30ac9d5baf98567b47a6525 (feat: ip/port type biz service vpc is not required). - Enhanced logging for remote execution: Logging around remote execution commands was improved to provide clearer request/response details, aiding monitoring and troubleshooting. Commit: e8aa07052a9a961ed9eedb90b5324f9a3760c9db (feat: optimize remote execute log).
