Kristi Tsukida, a staff engineer at Quantcast, explains how the Ad Tech company is using Aerospike to replace a legacy system that stored user history for ad targeting. The previous system lacked flexibility, limiting the company’s ability to improve product offerings. With Aerospike, Quantcast anticipates being able to access more datasets in real-time, enabling better ad-targeting decisions and providing value to marketers. The transition to Aerospike has been surprisingly easy, with the key-value store proving to be scalable, maintainable, and reliable, backed by excellent support from Aerospike’s team.
