May 1, 2025May 2025 monthly summary focused on strengthening stream reliability and preparing for a partial testnet upgrade through observability enhancements and P2P refactoring. Key features delivered: - Stream Read Observability Enhancements: added reason strings for stream removals and expanded logging on stream closures to improve failure diagnosis and MTTR; began investigation of a view-change anomaly where the next leader was the same as the current leader, informing future fixes. - P2P Stream Refactoring and Partial Testnet Upgrade Planning: initiated refactor work and drafted a phased release plan to evaluate Harmony compatibility in a staged testnet upgrade. Major bugs fixed: - No explicit bug fixes completed this month. The work focused on features and stabilization through improved observability. The view-change issue was investigated for future remediation. Overall impact and accomplishments: - Improved operational visibility enables faster detection and resolution of issues, reducing mean time to recovery during upgrades and incidents. - Establishes a safer upgrade path via partial testnet rollout and P2P refactor groundwork, reducing risk for full-scale deployments. Technologies/skills demonstrated: - Observability instrumentation and enhanced logging for distributed streams. - P2P stream architecture refactoring and release planning for phased upgrades. - Documentation and commit traceability (two commits updating gheis-mohammadi.md) as part of change management.
