September 2025 monthly summary for Altinn/altinn-broker: Focused on performance optimization of file transfer data retrieval with a concise, business-value oriented approach. Delivered a key feature improvement by refactoring the FileTransferRepository SQL to replace hardcoded constants with enum values and updated join conditions to enable faster retrieval of file transfer data by actor and status. This work is associated with commit 32995af38955cd3fdaf344dd3cc6d53326139cea ("Tuning of getfiles (#710)"). No major bug fixes were required this month; the emphasis was on performance gains and code quality. Impact: Reduced query latency for common file transfer lookups, improved scalability for larger datasets, and strengthened maintainability of the repository layer. Technologies/skills demonstrated: SQL query optimization, enum-based value usage over constants, repository pattern refactoring, performance tuning, and collaboration around issue #710.

Month 2025-08: Delivered performance and robustness enhancements to the Authorization Service in Altinn/altinn-authorization-tmp, focusing on multi-request throughput and resilient JSON handling. Key changes include (1) a temporary sorted list to speed up resource lookups for large multi-request calls, (2) migration of JSON deserialization to System.Text.Json for improved performance, and (3) enabling case-insensitive JSON deserialization in DecisionController to reduce input-related failures. Implemented via two commits supporting these goals: 5261f249c96c50137784a701e59107298e24e327 and e69ebef2f2ac1423a8d705ab49277fe8ef24b7d6. The work reduces latency for large request patterns, improves reliability of authorization checks, and sets groundwork for further performance optimizations.

April 2025 Monthly Summary: Focused on optimizing the authorization workflow in Altinn/altinn-authorization-tmp by delivering a targeted performance enhancement in the Xacml resource handling path. Key changes: - Added EndEventValue to XacmlResourceAttributes and updated ContextHandler.cs to short-circuit GetAuthInfo when EndEventValue or TaskValue is present, reducing unnecessary data retrieval and lowering authorization latency. - Change tracked in commit b0b69aad32b0bc2a6f39089bd680d31cfc21878a with message "Avoid calling GetAuthInfo (#555)". Key achievements (Top 3-5): - Implemented EndEventValue support for more precise authorization decisions. - Optimized authorization pipeline by short-circuiting redundant GetAuthInfo calls, cutting data retrieval overhead. - Centralized performance improvement in the authorization path, contributing to lower latency and higher throughput for authorization checks. - Clear, auditable change with a single targeted commit improving maintainability and traceability. Note on bugs fixed: No major fixes were reported this month; the focus was on performance optimization and feature enhancement to reduce latency in the authorization flow.
