Large scale distributed video processing with OTP
Video processing is both CPU and IO heavy. When it comes to Tubi, where the system need to process thousands of hours each week, it became a quite big challenge.
The Tubi team has created a way of breaking a single video process job to hundreds of tasks and distributed different tasks to different nodes that live in the same cluster. The cluster is built on OTP, the resources (CPU and IO) used by each task on each node are properly managed. Each task is doing a tiny bit of the whole thing, the input of each task may come from the output the task, both tasks may be running in different nodes.
