How do you import and export data in DynamoDB?

To import data into DynamoDB, you can use the following methods: 1. Use AWS CLI: You can use the `dynamodb batch-write-item` command in AWS CLI to import data in batches. First, save the data as a JSON or CSV file, then use the command to import the data into the DynamoDB table. 2. Use DynamoDB Import Tool: DynamoDB provides an official import tool to help you import data from other sources (such as DynamoDB, DynamoDB Local, CSV files, JSON files, etc.) into DynamoDB tables. You can find the import tool in the DynamoDB console in the AWS Management Console. 3. Use AWS Data Pipeline: AWS Data Pipeline is a fully managed ETL (Extract, Transform, Load) service that can help you import data from various sources (such as S3, RDS, DynamoDB, etc.) into DynamoDB tables. You can create a data pipeline in the AWS Management Console, configure the data sources and targets, and then trigger the data import job. To export data from DynamoDB, you can use one of the following methods: 1. Use AWS CLI: You can use the `dynamodb scan` command in AWS CLI to scan and export data from DynamoDB tables. The scan results will be returned as JSON format output. You can save the output to a file for further processing. 2. Use DynamoDB Export Tool: DynamoDB provides an official export tool to help you export data from DynamoDB tables to other sources (such as DynamoDB, DynamoDB Local, CSV files, JSON files, etc.). You can find the export tool in the DynamoDB console in the AWS Management Console. 3. Use AWS Data Pipeline: AWS Data Pipeline can also be used to export data from DynamoDB tables to other sources (such as S3, RDS, etc.). You can create a data pipeline in the AWS Management Console, configure the data sources and targets, and then trigger the data export job. Whether importing or exporting data, using the right tools and methods can make the task quick and convenient.
