AWS Managing duplicate objects

 AWS Managing duplicate objects

Managing duplicate objects in AWS typically involves identifying and removing duplicate data to optimize storage and ensure data consistency. Here are some common approaches

Identifying duplicates: Use AWS services like S3 Inventory, AWS Glue, or Athena to scan and identify duplicate objects based on criteria such as file name, size, or content.

Removing duplicates:

Manual deletion: Identify and delete duplicates manually using the AWS Management Console, AWS CLI, or SDKs.

Automated deletion: Use AWS Lambda functions triggered by S3 events to automatically identify and delete duplicates based on predefined rules.

Preventing duplicates:

Implement data validation checks to prevent duplicate uploads.

Use unique identifiers or metadata to track and manage objects to avoid duplicates.                                         - AWS Data Engineering Online Training

Versioning:

Enable versioning on your S3 bucket to retain all versions of an object. This can help in managing duplicates and restoring previous versions if needed.

Lifecycle policies:

Use S3 lifecycle policies to automatically transition or delete objects based on predefined rules. This can help manage duplicate or outdated objects more efficiently.                                     - AWS Data Engineering Training Ameerpet
