 ** AllocatedCapacity **   <a name="Glue-Type-JobUpdate-AllocatedCapacity"></a>
This field is deprecated. Use `MaxCapacity` instead.

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](https://aws.amazon.com/glue/pricing/).

 ** Description **   <a name="Glue-Type-JobUpdate-Description"></a>
Description of the job being defined.  
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 2048.

 ** ExecutionClass **   <a name="Glue-Type-JobUpdate-ExecutionClass"></a>
Indicates whether the job is run with a standard or flexible execution class. The standard execution-class is ideal for time-sensitive workloads that require fast job startup and dedicated resources.  
The flexible execution class is appropriate for time-insensitive jobs whose start and completion times may vary.   
Only jobs with AWS Glue version 3.0 and above and command type `glueetl` will be allowed to set `ExecutionClass` to `FLEX`. The flexible execution class is available for Spark jobs.

 ** GlueVersion **   <a name="Glue-Type-JobUpdate-GlueVersion"></a>
In Spark jobs, `GlueVersion` determines the versions of Apache Spark and Python that AWS Glue available in a job. The Python version indicates the version supported for jobs of type Spark.   
Ray jobs should set `GlueVersion` to `4.0` or greater. However, the versions of Ray, Python and additional libraries available in your Ray job are determined by the `Runtime` parameter of the Job command.  
For more information about the available AWS Glue versions and corresponding Spark and Python versions, see [Glue version](https://docs.aws.amazon.com/glue/latest/dg/add-job.html) in the developer guide.  
Jobs that are created without specifying a Glue version default to Glue 0.9.

Required: No

 ** JobMode **   <a name="Glue-Type-JobUpdate-JobMode"></a>
A mode that describes how a job was created. Valid values are:  
+  `SCRIPT` - The job was created using the AWS Glue Studio script editor.
+  `VISUAL` - The job was created using the AWS Glue Studio visual editor.
+  `NOTEBOOK` - The job was created using an interactive sessions notebook.
When the `JobMode` field is missing or null, `SCRIPT` is assigned as the default value.  
Type: String  
Valid Values: `SCRIPT | VISUAL | NOTEBOOK`   
Required: No

 ** JobRunQueuingEnabled **   <a name="Glue-Type-JobUpdate-JobRunQueuingEnabled"></a>
Specifies whether job run queuing is enabled for the job runs for this job.  
A value of true means job run queuing is enabled for the job runs. If false or not populated, the job runs will not be considered for queueing.  
If this field does not match the value set in the job run, then the value from the job run field will be used.  
Type: Boolean  
Required: No

 ** LogUri **   <a name="Glue-Type-JobUpdate-LogUri"></a>
This field is reserved for future use.  
Type: String  
Required: No

 ** MaintenanceWindow **   <a name="Glue-Type-JobUpdate-MaintenanceWindow"></a>
This field specifies a day of the week and hour for a maintenance window for streaming jobs. AWS Glue periodically performs maintenance activities. During these maintenance windows, AWS Glue will need to restart your streaming jobs.  
 AWS Glue will restart the job within 3 hours of the specified maintenance window. For instance, if you set up the maintenance window for Monday at 10:00AM GMT, your jobs will be restarted between 10:00AM GMT to 1:00PM GMT.  
Type: String  
Pattern: `^(Sun|Mon|Tue|Wed|Thu|Fri|Sat):([01]?[0-9]|2[0-3])$`

 ** MaxCapacity **   <a name="Glue-Type-JobUpdate-MaxCapacity"></a>
For Glue version 1.0 or earlier jobs, using the standard worker type, 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](https://aws.amazon.com/glue/pricing/).  
For Glue version 2.0\$1 jobs, you cannot specify a `Maximum capacity`. Instead, you should specify a `Worker type` and the `Number of workers`.  
Do not set `MaxCapacity` if using `WorkerType` and `NumberOfWorkers`.  
The value that can be allocated for `MaxCapacity` depends on whether you are running a Python shell job, an Apache Spark ETL job, or an Apache Spark streaming 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.

 ** Timeout **   <a name="Glue-Type-JobUpdate-Timeout"></a>
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.  
Jobs must have timeout values less than 7 days or 10080 minutes. Otherwise, the jobs will throw an exception.  
When the value is left blank, the timeout is defaulted to 2880 minutes.  
Any existing AWS Glue jobs that had a timeout value greater than 7 days will be defaulted to 7 days. For instance if you have specified a timeout of 20 days for a batch job, it will be stopped on the 7th day.  
For streaming jobs, if you have set up a maintenance window, it will be restarted during the maintenance window after 7 days.  
Type: Integer  
Valid Range: Minimum value of 1.  
Required: No

 ** WorkerType **   <a name="Glue-Type-JobUpdate-WorkerType"></a>
