In today’s modern distributed systems landscape, many tasks consist of batch processing, and parallel processing divides the jobs into smaller portions and units that can be executed in parallel. Kubernetes, also known for its container orchestration, provides an object called Job to handle such cases.

Not all batch jobs are similar. Depending on the details and nature of the task, some coordination is required between them; we might need different patterns for distributing such workloads. That is where the coarse parallel processing model fits in.
