  [Startup] CLP is deployed on Uber’s big data platform. In 2021, Uber’s growth eclipsed the capability of their existing log management tools, forcing them to start dropping Petabytes of INFO-level Spark logs due to scalability issues (e.g., capacity, SSD burn-out). We integrated CLP into their logging library (Log4j) on Uber’s big data platform, achieving a 169x compression ratio. Now, all logs are retained, and efficiently analyzed, at 169x less cost. Check out Uber’s Engineering Blog for more details. (Also checkout the Hacker News discussion.)
