Pachyderm Pipeline System (PPS) is the computational component of the Pachyderm platform that enables you to perform various transformations on your data. Pachyderm pipelines have the following main concepts:
A pipeline is a job-spawner that waits for certain conditions to be met. Most commonly, this means watching one or more Pachyderm repositories for new data. When a new data arrives, a pipeline executes a user-defined piece of code to perform an operation and process the data. Each of these executions is called a job.
A job is an individual execution of a pipeline. A job can succeed or fail. Within a job, data and processing can be broken up into individual units of work called datums.
A datum is the smallest indivisible unit of work within a job. Different datums can be processed in parallel within a job.
