💡 What
Replaced multiple chained
.reduce()passes over thesession.usageRecordsrelation array with a singlefor...ofloop in bothpackages/web/src/app/api/orgs/[orgSlug]/dashboard/sessions/route.tsandpackages/web/src/app/api/orgs/[orgSlug]/dashboard/sessions/[sessionId]/route.ts.🎯 Why
When processing large arrays fetched via Prisma's
includerelations, chaining multiple array methods (like.map()or.reduce()) requires the V8 engine to iterate over the entire array multiple times. By combining the calculation ofinputTokens,outputTokens, andestimatedCostUsdinto a single loop, we eliminate redundant iterations and array traversals, lowering CPU overhead and reducing memory bottlenecks.📊 Impact
.reduce().🔬 Measurement
Run
pnpm run testonpackages/weband observe that the logic results match perfectly, showing that the single-loop logic computes the totals identically to the previous triple-reduce logic.PR created automatically by Jules for task 10837783799934645001 started by @seonghobae
