Explore the development of Mnemosyne, a distributed indexing layer for big data, in this 52-minute Devoxx conference talk. Dive into the challenges faced by Brandwatch Audiences product and learn how they built a system capable of handling hundreds of millions of social network profiles, billions of posts, and tens of billions of follower graph edges in real-time. Discover the fusion of succinct data structures, free text search, in-memory computing with JVM, CUDA, and Kafka to create a high-performance solution. Gain insights into CAP theorem trade-offs, brute force approaches versus indexes, data structures for sorting billions of records in milliseconds, GPU problem-solving, and JVM implementation. Understand key design principles, data ingestion and storage techniques, in-memory computing concepts, and the use of bitmaps and sparse data structures. Evaluate the project's success and consider the feasibility and advisability of undertaking similar endeavors in your own work.
