Case Study: Snapdeal achieves sub-millisecond dynamic pricing and scalable low-latency performance with Aerospike

Snapdeal, India’s Largest Online Marketplace, Accelerates Personalized Web Experience With Aerospike

Snapdeal, one of India’s largest online marketplaces serving 20 million+ users and 20,000 sellers, faced a critical scaling challenge: real-time dynamic pricing, inventory and seller-rating updates were slowing as the business grew, and their MongoDB cache saw response times jump from ~5 ms to over a second. That degradation threatened the responsiveness of the shopping experience and risked lost revenue as sellers made frequent price and inventory changes.

Snapdeal moved its Java‑based inventory and pricing system to the Aerospike in‑memory NoSQL database on Amazon EC2, storing 100M+ objects in DRAM. Aerospike delivered predictable sub‑millisecond performance (95–99% of transactions within 10 ms), full replication for continuity, rapid deployment in days with minimal maintenance, and the best price/performance—resulting in higher throughput, lower costs and a consistently responsive customer experience even under heavy concurrent updates.
