- Replaces sequential `await` calls in the `getOrders` filtering loop with `Promise.all` to fetch all fulfillment statuses concurrently. - Stores fetched data in a Map to avoid redundant KV lookups during the response mapping phase. - Improves performance significantly (benchmark shows reduction from ~1000ms to ~70ms for 50 items).

💡 What:
I refactored the
getOrdersmethod insrc/services/AnalyticsService.jsto parallelize the retrieval of order fulfillment statuses from Cloudflare KV. Instead of fetching them one by one inside a loop, I now identify all candidate sessions, fetch their statuses concurrently usingPromise.all, and store them in a Map for efficient lookup.🎯 Why:
The previous implementation used
awaitinside aforloop, causing sequential blocking. For N orders, this resulted in N sequential round-trips to the KV store. With 50 orders and a 20ms latency per KV call, this would take ~1000ms. By parallelizing these calls, the total time is reduced to roughly the latency of the slowest single request (plus some overhead), theoretically O(1) instead of O(N) relative to network latency.📊 Measured Improvement:
I created a benchmark test
tests/services/AnalyticsService_getOrders.perf.test.jssimulating 50 sessions with a 20ms KV delay.Existing tests in
tests/services/AnalyticsService.perf.test.jsalso passed, ensuring no regressions.PR created automatically by Jules for task 12802145833129644312 started by @AJFrio
