How to Delete S3 Objects Quickly with ExecuteTasks

Procedure

| What You Need | Detailed Explanation |

|---|---|

| 1. AWS Account | An account for using various AWS (Amazon Web Services) services. If you don't have one yet, you need to create one on the AWS website. <ul> <li> Account Creation: Go to the AWS website and create an account according to the instructions. You will need to register your credit card information and phone number. </li> <li> Root User and IAM User: When you create an AWS account, a "root user" with all privileges is created. However, for security reasons, it is recommended to create an "IAM (Identity and Access Management) user" for daily work and grant only the necessary privileges. </li> </ul> |

| 2. AWS CLI (Command Line Interface) or SDK (Software Development Kit) | Tools for operating AWS services. <ul> <li> AWS CLI: A tool for operating AWS services from the command line (terminal). <ul> <li> Installation: Download and install the installer for each OS (Windows, macOS, Linux) from the AWS website. </li> <li> Settings: After installation, use the aws configure command to set AWS authentication information (access key ID, secret access key, etc.). </li> </ul> </li> <li> SDK: A library for operating AWS services from each programming language (Python, Java, JavaScript, etc.). <ul> <li> Installation: Install using the package manager (pip, Maven, npm, etc.) for each language. </li> <li> Settings: You need to set AWS authentication information when using the SDK. </li> </ul> </li> </ul> |

| 3. S3 Bucket to Delete | S3 (Simple Storage Service) is an object storage service provided by AWS. Specify the S3 bucket where the objects to be deleted are stored. <ul> <li> Checking Buckets: Check the name of the bucket where the objects to be deleted are stored from the AWS Management Console. </li> <li> Creating Buckets (if necessary): If you have not created a bucket yet, create it using the AWS Management Console or AWS CLI/SDK. </li> </ul> |

| 4. (Optional) Tools for Speeding Up | Tools for speeding up processing when deleting a large number of objects. <ul> <li> S3 Batch Operations: A service for executing batch processing on a large number of objects. It is possible to perform operations such as copying and tagging as well as deletion processing. </li> <li> Lifecycle Rules: A function that automatically manages the lifecycle (creation, storage, deletion, etc.) of objects in an S3 bucket. You can streamline the deletion process by setting up automatic deletion of old objects. </li> <li> Third-Party Tools: There are also tools specializing in deleting S3 objects. For example, s3-batch-delete uses S3 Batch Operations to achieve high-speed deletion processing. </li> </ul> |

Supplementary Information

 * IAM User Permissions: To delete S3 objects, you need appropriate IAM user permissions. Use an IAM user with permissions such as s3:DeleteObject.

 * Versioning: If versioning is enabled in the S3 bucket, past versions will remain even if you delete an object. To delete completely, you need to use the --versions option.

Alternatives

 * AWS Management Console: You can delete objects by GUI operation from the AWS web console. Suitable for deleting a small number of objects.

 * S3 Glacier: Objects transferred to S3 Glacier, an archive storage service, must be restored before deletion.

The above is an example of a detailed explanation. Please refer to the AWS documentation and support information for more detailed information.
