Creates a new job definition.
May throw InvalidInputException. May throw IdempotentParameterMismatchException. May throw AlreadyExistsException. May throw InternalServiceException. May throw OperationTimeoutException. May throw ResourceNumberLimitExceededException. May throw ConcurrentModificationException.
Parameter command
:
The JobCommand
that executes this job.
Parameter name
:
The name you assign to this job definition. It must be unique in your
account.
Parameter role
:
The name or Amazon Resource Name (ARN) of the IAM role associated with
this job.
Parameter allocatedCapacity
:
This parameter 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.
Parameter connections
:
The connections used for this job.
Parameter 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.
Parameter description
:
Description of the job being defined.
Parameter executionProperty
:
An ExecutionProperty
specifying the maximum number of
concurrent runs allowed for this job.
Parameter glueVersion
:
Glue version determines the versions of Apache Spark and Python that AWS
Glue supports. The Python version indicates the version supported for jobs
of type Spark.
For more information about the available AWS Glue versions and corresponding Spark and Python versions, see Glue version in the developer guide.
Jobs that are created without specifying a Glue version default to Glue 0.9.
Parameter logUri
:
This field is reserved for future use.
Parameter 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") or Apache Spark streaming ETL job (JobCommand.Name
="gluestreaming"), you can allocate from 2 to 100 DPUs. The default is 10 DPUs. This job type cannot have a fractional DPU allocation.
Parameter maxRetries
:
The maximum number of times to retry this job if it fails.
Parameter nonOverridableArguments
:
Non-overridable arguments for this job, specified as name-value pairs.
Parameter notificationProperty
:
Specifies configuration properties of a job notification.
Parameter 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
.
Parameter securityConfiguration
:
The name of the SecurityConfiguration
structure to be used
with this job.
Parameter tags
:
The tags to use with this job. You may use tags to limit access to the
job. For more information about tags in AWS Glue, see AWS
Tags in AWS Glue in the developer guide.
Parameter 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).
Parameter 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.
