# DDBELTConnectionOptions
<a name="API_DDBELTConnectionOptions"></a>

Specifies connection options for DynamoDB ELT (Extract, Load, Transform) operations. This structure contains configuration parameters for connecting to and extracting data from DynamoDB tables using the ELT connector.

## Contents

 ** DynamodbTableArn **   <a name="Glue-Type-DDBELTConnectionOptions-DynamodbTableArn"></a>
The Amazon Resource Name (ARN) of the DynamoDB table to extract data from. This parameter specifies the source table for the ELT operation.   
Type: String  
Pattern: `([\u0009\u000B\u000C\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF])*`   
Required: Yes

 ** DynamodbExport **   <a name="Glue-Type-DDBELTConnectionOptions-DynamodbExport"></a>
Specifies the export type for DynamoDB data extraction. This parameter determines how data is exported from the DynamoDB table during the ELT process.  
Type: String  
Valid Values: `ddb | s3`   
Required: No

 ** DynamodbS3Bucket **   <a name="Glue-Type-DDBELTConnectionOptions-DynamodbS3Bucket"></a>
The name of the Amazon S3 bucket used for intermediate storage during the DynamoDB ELT process. This bucket is used to temporarily store exported DynamoDB data before it is processed by the ELT job.  
Type: String  
Pattern: `([\u0009\u000B\u000C\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF])*`   
Required: No

 ** DynamodbS3BucketOwner **   <a name="Glue-Type-DDBELTConnectionOptions-DynamodbS3BucketOwner"></a>
The AWS account ID of the owner of the S3 bucket specified in `DynamodbS3Bucket`. This parameter is required when the S3 bucket is owned by a different AWS account than the one running the ELT job, enabling cross-account access to the intermediate storage bucket.  
Type: String  
Pattern: `([\u0009\u000B\u000C\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF])*`   
Required: No

 ** DynamodbS3Prefix **   <a name="Glue-Type-DDBELTConnectionOptions-DynamodbS3Prefix"></a>
The S3 object key prefix for files stored in the intermediate S3 bucket during the DynamoDB ELT process. This prefix helps organize and identify the temporary files created during data extraction.  
Type: String  
Pattern: `([\u0009\u000B\u000C\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF])*`   
Required: No

 ** DynamodbStsRoleArn **   <a name="Glue-Type-DDBELTConnectionOptions-DynamodbStsRoleArn"></a>
The Amazon Resource Name (ARN) of the AWS Security Token Service (STS) role to assume for accessing DynamoDB and S3 resources during the ELT operation. This role must have the necessary permissions to read from the DynamoDB table and write to the intermediate S3 bucket.   
Type: String  
Pattern: `([\u0009\u000B\u000C\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF])*`   
Required: No

 ** DynamodbUnnestDDBJson **   <a name="Glue-Type-DDBELTConnectionOptions-DynamodbUnnestDDBJson"></a>
A boolean value that specifies whether to unnest DynamoDB JSON format during data extraction. When set to `true`, the connector will flatten nested JSON structures from DynamoDB items. When set to `false`, the original DynamoDB JSON structure is preserved.  
Type: Boolean  
Required: No
