Walmart Labs Adopts Guavus SQLstream for Streaming SQL Analytics

We’re very excited to welcome Walmart Labs to the SQLstream community.  They will be using Guavus SQLstream to support the Analytics Team for Merchant Technologies.

Walmart’s Merchant Technology team oversees online and in-store search, pricing, catalog, content, inventory, replenishment, and fulfillment technology to provide the optimal experience for their merchants and customers.

Walmart Labs has adopted Apache Kafka to connect hundreds of microservices and teams and evolve to a company-wide multi-tenant data hub. In doing so, Walmart Labs discovered that dealing with hundreds of millions of products and thousands of sellers required a streaming analytics platform that was able to handle very high data volumes, the complexity of many different data types, and dynamically changing stream definitions.  Something that open-source and other commercial solutions were not able to easily address.

Given that this streaming data quality solution is primarily for Walmart’s data analysts, they also wanted an analyst-friendly experience that enables rapid deployment of real-time reports and analytics, in contrast to the traditional batch analytics they had been using.

“We looked at the market and found Guavus SQLstream to be the most mature SQL-compliant, streaming analytics solution that could handle the scale and complexity of Walmart,” says Leo Nagata, Director of Analytics at Walmart Labs.  “Not only did it empower our analysts to use their existing SQL skills, we also believe that StreamLab, SQLstream’s analyst-friendly development environment with intelligent suggestions, will provide better productivity and automation over other products we have seen in the market.”

Guavus SQLstream empowers Walmart Lab’s analysts with fully-standards-compliant streaming SQL, which their analysts already understand.  Plus, standards-compliant SQL avoids the inconsistencies of SQL-like or SQL-light approaches which necessitate low level coding to fill in the gaps.  

“Obviously, we are very excited to work with a technology leader like Walmart Labs as they look to change the way the world shops,” says Damian Black, CEO/Founder at SQLstream.  “We always saw great potential for streaming SQL in retail and it’s great to see Walmart leading the way as the industry starts to see the value of real-time insight.”
