April 2025 (wandb/weave) monthly summary focusing on end-to-end storage footprint visibility, performance improvements, reliability fixes, and code quality gains across API, backend, and frontend. This release materially improves observability of storage and trace metrics, enhances data loading performance, and strengthens reliability of dashboards and queries. Key features delivered: - Storage footprint visibility across API and UI: added storage size to API and display it in Trace view, call summaries, and object details; frontend project-wide storage and trace size displays; backend stats queries now include storage size; project-level file size totals retrievable. - Input handling improvements: loosened regex to accept potentially CJK characters to improve data ingestion without breaking existing workflows. - Codebase and maintainability: removed TSLint from weave project; refactored cache key usage for cleaner, more reliable caching; added subquery alias support to queries. - UX enhancements: clearer trace endpoint error messaging to guide users; frontend/backend alignments to surface storage/trace size consistently. Major bugs fixed: - Trace Size Filter robustness: fixed case where Trace Size could become a filter condition leading to behavior inconsistencies. - Reliability of table queries: ensured 500 errors are correctly triggered on failures in table_query_stats and fixed related validation issues; uncommented validation checks and fixed the query as needed. - Data accuracy fixes: corrected bytes calculation to reflect actual payload sizes; fixed product-impact related issue to prevent downstream problems. Overall impact and accomplishments: - Increased observability and business value by surfacing storage footprint across the stack, enabling cost-conscious storage planning and faster decision-making. - Improved performance and reliability of dashboards and data loading pipelines, reducing latency and support tickets. - Strengthened code quality, consistency, and developer experience through targeted maintenance work. Technologies/skills demonstrated: - Frontend/UI work (storage/trace size displays, error messaging, and project-wide views) - Backend metrics and stats queries (including storage size in stats, file size totals) - Data performance tuning and evaluation comparison - Input validation, regex refinement for internationalization (CJK) - Code quality, build tooling cleanup, and caching architecture
