A map of arguments used to configure the `DevEndpoint`.  
Valid arguments are:  
+  `"--enable-glue-datacatalog": ""` 
You can specify a version of Python support for development endpoints by using the `Arguments` parameter in the `CreateDevEndpoint` or `UpdateDevEndpoint` APIs. If no arguments are provided, the version defaults to Python 2.

 ** GlueVersion **   <a name="Glue-Type-DevEndpoint-GlueVersion"></a>
Glue version determines the versions of Apache Spark and Python that AWS Glue supports. The Python version indicates the version supported for running your ETL scripts on development endpoints.   
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.  
Development endpoints that are created without specifying a Glue version default to Glue 0.9.  
You can specify a version of Python support for development endpoints by using the `Arguments` parameter in the `CreateDevEndpoint` or `UpdateDevEndpoint` APIs. If no arguments are provided, the version defaults to Python 2.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 255.

The status of the last update.  
Type: String  
Required: No

 ** NumberOfNodes **   <a name="Glue-Type-DevEndpoint-NumberOfNodes"></a>
The number of AWS Glue Data Processing Units (DPUs) allocated to this `DevEndpoint`.  
Type: Integer  
Required: No

 ** NumberOfWorkers **   <a name="Glue-Type-DevEndpoint-NumberOfWorkers"></a>
The number of workers of a defined `workerType` that are allocated to the development endpoint.  
The maximum number of workers you can define are 299 for `G.1X`, and 149 for `G.2X`.   
Type: Integer  
Required: No

 ** PrivateAddress **   <a name="Glue-Type-DevEndpoint-PrivateAddress"></a>
A private IP address to access the `DevEndpoint` within a VPC if the `DevEndpoint` is created within one. The `PrivateAddress` field is present only when you create the `DevEndpoint` within your VPC.  
Type: String  
Required: No

 ** PublicAddress **   <a name="Glue-Type-DevEndpoint-PublicAddress"></a>
The public IP address used by this `DevEndpoint`. The `PublicAddress` field is present only when you create a non-virtual private cloud (VPC) `DevEndpoint`.  
Type: String  
Required: No

 ** PublicKey **   <a name="Glue-Type-DevEndpoint-PublicKey"></a>
The public key to be used by this `DevEndpoint` for authentication. This attribute is provided for backward compatibility because the recommended attribute to use is public keys.  
Type: String  
Required: No

 ** PublicKeys **   <a name="Glue-Type-DevEndpoint-PublicKeys"></a>
A list of public keys to be used by the `DevEndpoints` for authentication. Using this attribute is preferred over a single public key because the public keys allow you to have a different private key per client.  
If you previously created an endpoint with a public key, you must remove that key to be able to set a list of public keys. Call the `UpdateDevEndpoint` API operation with the public key content in the `deletePublicKeys` attribute, and the list of new keys in the `addPublicKeys` attribute.
Type: Array of strings  
Array Members: Maximum number of 5 items.  
Required: No

 ** RoleArn **   <a name="Glue-Type-DevEndpoint-RoleArn"></a>
The Amazon Resource Name (ARN) of the IAM role used in this `DevEndpoint`.  
Type: String  
Pattern: `arn:aws:iam::\d{12}:role/.*`   
Required: No

 ** SecurityConfiguration **   <a name="Glue-Type-DevEndpoint-SecurityConfiguration"></a>
The name of the `SecurityConfiguration` structure to be used with this `DevEndpoint`.

The subnet ID for this `DevEndpoint`.  
Type: String  
Required: No

 ** VpcId **   <a name="Glue-Type-DevEndpoint-VpcId"></a>
The ID of the virtual private cloud (VPC) used by this `DevEndpoint`.  
Type: String  
Required: No

 ** WorkerType **   <a name="Glue-Type-DevEndpoint-WorkerType"></a>
The type of predefined worker that is allocated to the development endpoint. 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.
Known issue: when a development endpoint is created with the `G.2X` `WorkerType` configuration, the Spark drivers for the development endpoint will run on 4 vCPU, 16 GB of memory, and a 64 GB disk.   
Type: String  
Valid Values: `Standard | G.1X | G.2X | G.025X | G.4X | G.8X | Z.2X`   
Required: No
