Join us as we explore how KRAFTON optimized data governance for PUBG IP, enhancing cost efficiency and scalability. KRAFTON operates a massive data ecosystem, processing tens of terabytes daily. As real-time analytics demands increased, traditional Batch-based processing faced scalability challenges. To address this, we redesigned data pipelines and governance models, improving performance while reducing costs. Transitioned to real-time pipelines (batch to streaming) Optimized workload management (reducing all-purpose clusters, increasing Jobs usage) Cut costs by tens of thousands monthly (up to 75%) Enhanced data storage efficiency (lower S3 costs, Delta Tables) Improved pipeline stability (Medallion Architecture) Gain insights into how KRAFTON scaled data operations, leveraging real-time analytics and cost optimization for high-traffic games.
