Paul Lathrop: Senior Infrastructure Engineer at Krux


Krux delivers data fabric for the consumer web. Krux’s data management platform (DMP) helps companies protect, manage, and monetize across screens and sources.


Krux needs to work fast behind the scenes while managing a large amount

of data that includes more than one terabyte of client data and 50,000 requests per second.

the company began maxing out the single machine that handled its old data store,

even after upgrading the memory.


Their application requires high availability and low latency, so the company needed a database solution that would allow it to deliver fast, actionable, profitable insights to clients while scaling its business. With a growing customer base requiring it to store more customer data, Krux needed a storage system that could expand horizontally to every new device and browser.


Krux uses Cassandra with DataStax Enterprise to support three key use cases — its user data service, its ETL-like system for offline analysis and reporting, and a dynamic audience generation service that allows its clients to perform content targeting.
