Case Study: Mercado Libre achieves fast, scalable marketplace search with Elastic

MercadoLibre Powering Latin America's premier online marketplace

Mercado Libre, Latin America’s leading online marketplace, needed a faster, more reliable way for millions of sellers to search and manage product data across a rapidly growing catalog. Before Elastic, its Redis and MongoDB setups struggled with search functionality, scalability, and uptime, making it difficult to support 4 million sellers and tens of millions of listings.

Elastic implemented Elasticsearch to power Mercado Libre’s seller-facing “My Account” and other search APIs, delivering real-time search, 24/7 availability, and easy scaling. The results included searchable items within 1–2 seconds of publishing, order search response times cut to 100 milliseconds for large sellers, and the ability to add servers in seconds while reducing maintenance and downtime.
