BatchJobSpecification Class

Specifies details of the Jobs to be created on a schedule.

Constructor

BatchJobSpecification(*args: Any, **kwargs: Any)

Variables

Name	Description
priority	int The priority of Jobs created under this schedule. Priority values can range from -1000 to 1000, with -1000 being the lowest priority and 1000 being the highest priority. The default value is 0. This priority is used as the default for all Jobs under the Job Schedule. You can update a Job's priority after it has been created using by using the update Job API.
allow_task_preemption	bool Whether Tasks in this job can be preempted by other high priority jobs. (This property is not available by default. Please contact support for more information) If the value is set to True, other high priority jobs submitted to the system will take precedence and will be able requeue tasks from this job. You can update a job's allowTaskPreemption after it has been created using the update job API.
max_parallel_tasks	int The maximum number of tasks that can be executed in parallel for the job. (This property is not available by default. Please contact support for more information) The value of maxParallelTasks must be -1 or greater than 0 if specified. If not specified, the default value is -1, which means there's no limit to the number of tasks that can be run at once. You can update a job's maxParallelTasks after it has been created using the update job API.
display_name	str The display name for Jobs created under this schedule. The name need not be unique and can contain any Unicode characters up to a maximum length of 1024.
uses_task_dependencies	bool Whether Tasks in the Job can define dependencies on each other. The default is false.
all_tasks_complete_mode	str or BatchAllTasksCompleteMode The action the Batch service should take when all Tasks in a Job created under this schedule are in the completed state. Note that if a Job contains no Tasks, then all Tasks are considered complete. This option is therefore most commonly used with a Job Manager task; if you want to use automatic Job termination without a Job Manager, you should initially set onAllTasksComplete to noaction and update the Job properties to set onAllTasksComplete to terminatejob once you have finished adding Tasks. The default is noaction. Known values are: "noaction" and "terminatejob".
task_failure_mode	str or BatchTaskFailureMode The action the Batch service should take when any Task fails in a Job created under this schedule. A Task is considered to have failed if it have failed if has a failureInfo. A failureInfo is set if the Task completes with a non-zero exit code after exhausting its retry count, or if there was an error starting the Task, for example due to a resource file download error. The default is noaction. Known values are: "noaction" and "performexitoptionsjobaction".
network_configuration	BatchJobNetworkConfiguration (This property is not available by default. Please contact support for more information) The network configuration for the Job.
constraints	BatchJobConstraints The execution constraints for Jobs created under this schedule.
job_manager_task	BatchJobManagerTask The details of a Job Manager Task to be launched when a Job is started under this schedule. If the Job does not specify a Job Manager Task, the user must explicitly add Tasks to the Job using the Task API. If the Job does specify a Job Manager Task, the Batch service creates the Job Manager Task when the Job is created, and will try to schedule the Job Manager Task before scheduling other Tasks in the Job.
job_preparation_task	BatchJobPreparationTask The Job Preparation Task for Jobs created under this schedule. If a Job has a Job Preparation Task, the Batch service will run the Job Preparation Task on a Node before starting any Tasks of that Job on that Compute Node.
job_release_task	BatchJobReleaseTask The Job Release Task for Jobs created under this schedule. The primary purpose of the Job Release Task is to undo changes to Nodes made by the Job Preparation Task. Example activities include deleting local files, or shutting down services that were started as part of Job preparation. A Job Release Task cannot be specified without also specifying a Job Preparation Task for the Job. The Batch service runs the Job Release Task on the Compute Nodes that have run the Job Preparation Task.
common_environment_settings	list[EnvironmentSetting] A list of common environment variable settings. These environment variables are set for all Tasks in Jobs created under this schedule (including the Job Manager, Job Preparation and Job Release Tasks). Individual Tasks can override an environment setting specified here by specifying the same setting name with a different value.
pool_info	BatchPoolInfo The Pool on which the Batch service runs the Tasks of Jobs created under this schedule. Required.
metadata	list[BatchMetadataItem] A list of name-value pairs associated with each Job created under this schedule as metadata. The Batch service does not assign any meaning to metadata; it is solely for the use of user code.
