Web API Reference (API Version 2017-03-31)

JobUpdate

Specifies information used to update an existing job definition. The previous job definition is completely overwritten by this information.

Contents

AllocatedCapacity

This field is deprecated. Use MaxCapacity instead.

The number of AWS Glue data processing units (DPUs) to allocate to this job. You can allocate from 2 to 100 DPUs; the default is 10. A DPU is a relative measure of processing power that consists of 4 vCPUs of compute capacity and 16 GB of memory. For more information, see the AWS Glue pricing page.

Type: Integer

Required: No

Command

The JobCommand that executes this job (required).

Type: JobCommand object

Required: No

Connections

The connections used for this job.

Type: ConnectionsList object

Required: No

DefaultArguments

The default arguments for this job.

You can specify arguments here that your own job-execution script consumes, as well as arguments that AWS Glue itself consumes.

For information about how to specify and consume your own Job arguments, see the Calling AWS Glue APIs in Python topic in the developer guide.

For information about the key-value pairs that AWS Glue consumes to set up your job, see the Special Parameters Used by AWS Glue topic in the developer guide.

Type: String to string map

Required: No

Description

Description of the job being defined.

Type: String

Length Constraints: Minimum length of 0. Maximum length of 2048.

Pattern: [\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF\r\n\t]*

Required: No

ExecutionProperty

An ExecutionProperty specifying the maximum number of concurrent runs allowed for this job.

Type: ExecutionProperty object

Required: No

LogUri

This field is reserved for future use.

Type: String

Required: No

MaxCapacity

The number of AWS Glue data processing units (DPUs) that can be allocated when this job runs. A DPU is a relative measure of processing power that consists of 4 vCPUs of compute capacity and 16 GB of memory. For more information, see the AWS Glue pricing page.

Do not set Max Capacity if using WorkerType and NumberOfWorkers.

The value that can be allocated for MaxCapacity depends on whether you are running a Python shell job or an Apache Spark ETL job:

  • When you specify a Python shell job (JobCommand.Name="pythonshell"), you can allocate either 0.0625 or 1 DPU. The default is 0.0625 DPU.

  • When you specify an Apache Spark ETL job (JobCommand.Name="glueetl"), you can allocate from 2 to 100 DPUs. The default is 10 DPUs. This job type cannot have a fractional DPU allocation.

Type: Double

Required: No

MaxRetries

The maximum number of times to retry this job if it fails.

Type: Integer

Required: No

NotificationProperty

Specifies the configuration properties of a job notification.

Type: NotificationProperty object

Required: No

NumberOfWorkers

The number of workers of a defined workerType that are allocated when a job runs.

The maximum number of workers you can define are 299 for G.1X, and 149 for G.2X.

Type: Integer

Required: No

Role

The name or Amazon Resource Name (ARN) of the IAM role associated with this job (required).

Type: String

Required: No

SecurityConfiguration

The name of the SecurityConfiguration structure to be used with this job.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 255.

Pattern: [\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF\t]*

Required: No

Timeout

The job timeout in minutes. This is the maximum time that a job run can consume resources before it is terminated and enters TIMEOUT status. The default is 2,880 minutes (48 hours).

Type: Integer

Valid Range: Minimum value of 1.

Required: No

WorkerType

The type of predefined worker that is allocated when a job runs. Accepts a value of Standard, G.1X, or G.2X.

  • For the Standard worker type, each worker provides 4 vCPU, 16 GB of memory and a 50GB disk, and 2 executors per worker.

  • For the G.1X worker type, each worker maps to 1 DPU (4 vCPU, 16 GB of memory, 64 GB disk), and provides 1 executor per worker. We recommend this worker type for memory-intensive jobs.

  • For the G.2X worker type, each worker maps to 2 DPU (8 vCPU, 32 GB of memory, 128 GB disk), and provides 1 executor per worker. We recommend this worker type for memory-intensive jobs.

Type: String

Valid Values: Standard | G.1X | G.2X

Required: No
