ScyllaDB - Tracking Millions of Heartbeats on ZEE’s Streaming Platform

“ZEE is India’s largest media and entertainment business, covering broadcast TV, films,  streaming media, and music. ZEE5 is their premier OTT streaming service, available in over 190 countries with ~150M monthly active users. And every user’s playback experience, security, and recommendations rely upon a “heartbeat API” that processes a whopping 100B+ heartbeats per day. The engineers behind the system knew that continued business growth would stress their infrastructure (as well as the people reviewing the database bills). So, the team decided to rethink the system before it inflicted any heart attacks. TL;DR, they designed a system that’s loved internally and by users. And Jivesh Threja (Tech Lead) and Srinivas Shanmugam (Principal Architect) joined us on Valentine’s Day last year to share their experiences.”
