Apr 1, 2025

April 2025 monthly summary for Azure/durabletask focusing on strengthening robustness and observability in core task orchestration and Azure Storage integration. Delivered two key features: enhanced CreateTimer validation and rich activity context in DurableTask Core, and storage read metrics in the Azure Storage Durable Task provider, including a refactor to DownloadLeaseBlob and updated TableQueryResponse to track entities read. These changes were accompanied by updating DurableTask.Core version to align APIs and improve runtime observability. No major bugs fixed were documented in this period.

Dec 1, 2024

December 2024 monthly summary for Azure/azure-functions-durable-extension: Implemented consistent scaler IDs across target-based scaling and scale monitor implementations, with a refactor to use a single ID generation entry point (GetScalerUniqueId). This unifies ID handling and reduces cross-implementation discrepancies. Fixed a flaky integration test related to scaler ID usage, improving test reliability and release confidence. Commit: 93eddb68c2a6c1bcb199c775d6881dde658388bc. Resulting in more predictable auto-scaling behavior, reduced operational risk, and a cleaner architecture for scaling components.

Nov 1, 2024

Month 2024-11 — Azure/azure-functions-durable-extension: Delivered a performance-oriented refactor to the Durable Task extension to create per-task hub singletons for DurableTaskScaleMonitor and DurableTaskTargetScaler inside AzureStorageDurabilityProvider, reducing storage polling costs for large numbers of durable-trigger functions and simplifying descriptors by removing unnecessary function-specific identifiers. This work, captured in commit 860216c1df60651ebfe0bd687b9eb41da0da8148 (Make scalers into per-task hub singletons), lays groundwork for better scalability and lower run-time costs.
