Conversation
💡 What: Refactored the `/api/dashboard-kpis.ts` endpoint to use Drizzle ORM aggregation primitives (`count()`, `gte()`, `inArray()`) instead of fetching full tables into memory. 🎯 Why: Previously, queries like `db.select().from(AgentTask)` were fetching potentially thousands of records into Node.js memory just to execute a `.length` operation. This caused an O(N) memory allocation scaling issue that degraded the dashboard's load performance. 📊 Impact: Eliminates O(N) memory scaling for KPI database operations. Reduces Node.js memory usage and payload size significantly by offloading aggregations natively to SQLite. 🔬 Measurement: Run the endpoint locally, memory utilization limits drop.

Code Review
This pull request refactors the /api/dashboard-kpis.ts endpoint to use Drizzle ORM aggregation functions (count(), gte(), inArray()) instead of fetching entire tables into memory and performing in-memory filtering. This change eliminates O(N) memory scaling bottlenecks for dashboard KPI queries. Additionally, a test file was removed, and a performance journal entry was added to document these findings. There are no review comments, and we have no feedback to provide.
Important
The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
