Meta has rolled out a new feature in their Download Your Information tool, known as data logs, aimed at improving user transparency and control over personal data. The development faced hurdles due to Meta's operational scale and inefficiencies in their data warehouse system, Hive. As a solution, Meta created a batching approach that optimizes data retrieval, minimizing the processing of irrelevant information. This system is supported by their internal task-scheduling service and leverages advanced data processing technologies to ensure reliable and efficient data handling.
