# Showing Delivery SLA at 10x Scale with 1/10th Latency

**[Flipkart Tech](https://daily.dev/sources/flipkart)** · 18 min read · 0 upvotes · 0 comments

## Summary

Flipkart's Promise team aimed to display delivery dates for products on its Search and Browse page within a stringent latency constraint of 100ms for a batch of 100 items. They tackled this challenge by innovating the existing computation flow, optimizing source and vendor capacity stores, and employing caching techniques using Aerospike. These changes enabled real-time delivery date calculations with over 90% accuracy at large scale QPS without compromising user experience.
