Feb 1, 2026

February 2026 (2026-02): Focused on strengthening Resource Manager lifecycle reliability in viamrobotics/rdk. Delivered Resource Manager Resilience: Re-add Resources After Module Restart, which automatically re-adds resources after a module restart to reduce orphaned resources and improve overall system stability. This work aligns with RSDK-13250 and was implemented in commit 8fcae40ab3f30de07259ba9f45df6e21750ed07c (PR #5710), with collaboration from Cheuk.

April 2025 — viamrobotics/rdk: Focused on reliability and observability enhancements. Key changes include batching resource additions to batches of 10 to reduce concurrency issues, and expanding unary request counting across namespaces with a refactor to derive the service name from the resource name for more granular telemetry. These efforts, captured in commits c9090803e3a196d12b78d2a2fce2f1407d483069 (RSDK-10495) and 4d9950618a6f8060a64cf29fd15643c337cf6e0f (RSDK-9893), lay groundwork for improved stability and better metrics in high-load scenarios. No explicit bug fixes were recorded this month; the work delivered aligns with reliability and telemetry objectives.
