Social Media

With over 250 million users worldwide, Discord operates as a voice, video, and text communication service, where people talk and hang out with friends and communities. Discord migrated from Apache Cassandra to ScyllaDB to achieve the predictable low latencies required to drive their high-volume homepage personalization engine.

Kik lets users connect with friends, groups, and the world around them through chat. Kik messenger moved their instant messaging data platform from Apache Cassandra to ScyllaDB Cloud.

IMVU is an online metaverse and social networking site where members create 3D avatars to meet new people, chat, create, and play games. Members also participate in a vibrant virtual economy, creating and selling products in the IMVU catalog. IMVU eliminated a cache-based solution by migrating from Redis to ScyllaDB, achieving a scalable solution capable of supporting hundreds of thousands of concurrent users with low latency and predictable performance.

Zenly is a free smartphone app that enables friends and family to follow each other’s locations on a map in real-time. The app is update-heavy: a two-minute old location is already outdated. With Cassandra, application threads would stop for too long, and, with Zenly’s small clusters, Java garbage collection was a deal-breaker. With ScyllaDB, Zenly was able to eliminate their cache, while achieving 100% uptime and p99 latencies under 3 milliseconds.
