S3 Inventory & Object Tagging

Introduction

Amazon S3 provides a robust way to manage and analyze your data stored in the cloud. Two of the key features that enhance data management are S3 Inventory and Object Tagging. This lesson will explore how these features can be effectively utilized within your AWS data engineering workflows.

Key Concepts

• S3 Inventory: A feature that allows you to create and manage a list of your objects stored in S3 buckets.
• Object Tagging: A method to categorize and manage S3 objects using key-value pairs.
• Data Lake: A centralized repository that allows you to store all your structured and unstructured data at any scale.

S3 Inventory

S3 Inventory provides a scheduled alternative to the S3 List API for collecting object metadata. It can help you track storage usage and analyze data.

Features of S3 Inventory

• Delivers CSV, ORC, or Parquet format reports.
• Provides information about each object, including size, last modified date, and storage class.
• Supports daily or weekly reporting frequency.

How to Set Up S3 Inventory

1. Open the Amazon S3 console.
2. Select the bucket for which you want to enable inventory.
3. Choose the Management tab.
4. Select Inventory and then click Create Inventory Configuration.
5. Specify the inventory name and destination bucket.
6. Choose the report format (CSV, ORC, Parquet).
7. Set the frequency (daily or weekly) and click Create.

Object Tagging

Object Tagging allows you to categorize your S3 objects with metadata in the form of key-value pairs. This can help in managing access control, organizing data, and controlling costs.

Common Use Cases for Object Tagging

• Cost allocation by project or department.
• Data lifecycle management based on tags.
• Access control through IAM policies based on tags.

How to Tag S3 Objects

1. Open the Amazon S3 console.
2. Select the bucket and navigate to the object you want to tag.
3. Choose Actions and then Edit tags.
4. Add your key-value pairs and click .

Code Example: Adding Tags Using AWS SDK for Python (Boto3)

import boto3

s3 = boto3.client('s3')

# Add tags to an object
response = s3.put_object_tagging(
    Bucket='your-bucket-name',
    Key='your-object-key',
    Tagging={
        'TagSet': [
            {
                'Key': 'project',
                'Value': 'data-engineering'
            },
            {
                'Key': 'environment',
                'Value': 'production'
            },
        ]
    }
)
print(response)
            

Best Practices

• Use S3 Inventory to regularly audit your data and ensure compliance.
• Tag objects consistently and use a standardized naming convention.
• Review and analyze your inventory reports to optimize storage costs.
• Consider lifecycle policies based on object tags to automate data management.
