JobSet

JobSet is a software abstraction that represents a collection of computational tasks, or jobs, intended to be executed as a unit. A JobSet typically includes metadata such as dependencies between jobs, resource requirements, priorities, and time constraints. The concept is used to simplify submission to schedulers, manage parallel execution, and track overall progress.

Common operations on a JobSet include adding and removing jobs, querying status, submitting the set to a runner or queue, and synchronizing completion (waiting for all jobs to finish). Implementations often support handling failures by retrying individual jobs, aborting the entire set, or resubmitting affected tasks. Some variants provide mechanisms for partial success, enabling downstream jobs to start as soon as their prerequisites are satisfied within the set.

JobSet appears in a variety of contexts, including batch processing systems, distributed computing frameworks, workflow engines, and continuous integration pipelines. In these environments, a JobSet serves as a controllable unit of work that can be scheduled, monitored, and governed according to resource policies and reliability requirements.

Design considerations for JobSet implementations include support for dependencies, fault tolerance, and retry policies; clear status reporting; reproducibility of executions; and the ability to specify resource constraints such as CPU, memory, and time limits. Some designs emphasize immutability after submission to prevent changes that could affect correctness, while others allow dynamic updates prior to execution.

History and usage vary by system; the term JobSet is used across multiple software ecosystems without a single universal standard. It is commonly encountered in batch schedulers, cloud orchestration tools, and data processing pipelines.
