Core Concepts

Job

A Job represents a complete batch processing task. It consists of one or more Steps that are executed in a specific sequence. Each Job has a unique name and can be configured with various parameters and listeners. For detailed information about Jobs, see Job.

Step

A Step is a single phase in a Job that encapsulates an independent unit of processing. GoBatch supports three types of steps:

• Simple Step: Executes a single task in one thread
• Chunk Step: Processes data in chunks (read-process-write pattern)
• Partition Step: Splits a large task into multiple sub-tasks for parallel processing

For detailed information about Steps, see Step.

JobInstance

A JobInstance represents a logical run of a Job, uniquely identified by the Job name and job parameters. Multiple JobExecutions may be created for a single JobInstance in case of failures.

JobExecution

A JobExecution represents a single attempt to execute a JobInstance. Each execution tracks its status, start time, end time, and execution results.

StepExecution

A StepExecution represents a single attempt to execute a Step within a JobExecution. It contains information about the step's execution status and results.
