These are just some of the many integrations available with AWS S3 Batch Operations. With this powerful tool, businesses can automate their data processing workflows and gain more insight into the performance of their cloud applications.

Some Features:

  • Job Cloning: With the Amazon S3 batch process, you are able to effortlessly duplicate a current job and adjust its parameters before sending it off as an all-new task. These cloned tasks can reproduce failed jobs or make any other necessary revisions for existing ones.
  • Programmatic Job Creation: To optimize your workflow, consider integrating a Lambda function into the bucket where your inventory reports are automatically generated. This way, as soon as a report arrives in the specific inventory folder, you can launch an automated batch job without waiting for human confirmation – it’s instant!
  • Job Priorities: You can have several jobs running simultaneously in each AWS region, with higher priority jobs taking precedence. If you need to adjust a job’s execution, select the active job and click Update Priority.
  • CSV Object Lists: Struggling to identify objects within an S3 bucket with no common prefix? Building a CSV file is the perfect solution! Start by generating an inventory report, then filter out desired items based on their name or reference. For example, if you’re utilizing Amazon Comprehend for sentiment analysis of your documents, use the generated inventory report to add any new unanalyzed documents into a CSV file. This way, you can easily and quickly build up your subset without manually searching through each item in the bucket!

Manifest object ETag

Manifest object ETag is a powerful feature of Amazon S3 Batch Operations that helps ensure data processing jobs’ integrity. The Manifest object ETag is an identifier used by Amazon S3 to track each file or folder in an S3 batch job and detect any changes made to them during the execution process. This helps you to avoid processing the same data twice or skipping data that has been updated since the last time it was processed.

Each file or folder is assigned a unique Manifest object ETag when running a batch job. The ETag is then used to check for any changes made to the file or folder during the execution of the job. If any changes are detected, the job will fail, and an error message will be thrown. This helps to make sure that only the most up-to-date version of a file or folder is processed, ensuring accuracy and consistency in your data processing jobs.

Overall, Manifest object ETag is an excellent tool for ensuring the integrity of your S3 batch jobs and is an invaluable asset for businesses that rely heavily on Amazon S3 Batch Operations.

Why would we use Amazon S3 Batch Operation instead of triggering a Lambda function directly from an S3 Bucket configured for a Prefix?

Amazon S3 Batch Operations allows for automated, large-scale operations on many objects in an S3 bucket at once. This is beneficial when many objects are in the bucket, and individually triggering Lambda functions would be resource-intensive and time-consuming. Additionally, Amazon S3 Batch Operations can easily integrate with other AWS Services, such as Amazon EMR and AWS Lambda, to perform multiple tasks in parallel. This allows for faster data processing since multiple tasks can be processed simultaneously rather than one at a time. By leveraging the automation capabilities of S3 Batch Operations, users can save money on compute costs associated with running individual Lambda functions per object in an S3 bucket. Furthermore, S3 Batch Operations can be configured to perform specific operations on objects in an S3 bucket based on certain criteria, such as object size or type. This makes it easier to manage large-scale data operations efficiently and cost-effectively.

How to set up an AWS S3 Batch Operation

Setting up an AWS S3 Batch Operation can be intimidating at first glance, but the process is relatively simple after creating a Role with appropriate IAM permissions. This Role should have access to upload, list, download and delete objects in the Amazon S3 bucket. Additionally, if you are working with a Cross Account setup, then you may need to enable access from another account. Once those steps have been completed, an AWS S3 Batch Operation can easily be set up and launched without too much additional preparation.

Amazon S3 Inventory and S3 Batch Operations

The S3 Inventory feature of Amazon Simple Storage Service (S3) is closely related to AWS S3 Batch Operations as it provides a reliable way to track, manage and audit the content stored in S3. It allows customers to generate individual inventory reports that list object metadata for all objects within a specified bucket or prefix. This can be useful for identifying duplicate objects and assessing the security of an S3 bucket. With S3 Inventory, customers have the ability to quickly identify things that need further attention by analyzing the object’s metadata in an easily readable CSV format.

With AWS S3 Batch Operations, customers can use this generated inventory (manifest) report as a source of inputs to perform a series of operations on all objects in the inventory.

Giving permissions

Before launching S3 Batch Operations, it is essential to grant suitable permissions. For example, suppose you want to carry out an Amazon S3 Batch Operation job. In that case, you must provide s3:CreateJob permission and allow iam:PassRole authorization for that individual in order to assign a particular AWS Identity and Access Management (IAM) role related to this specific job over to Batch Operations.

Before determining the ideal permissions for your operations, consider one of these policies to ensure smooth running. There is a policy that would fit perfectly with whatever type of operations you are managing:

  • In any situation, Amazon S3 should possess the authority to access your manifest object from your bucket and potentially submit a report. Therefore, all policies specified below comprise these permissions.
  • To manage your Amazon S3 Inventory report manifests efficiently, you must grant permission to S3 Batch Operations to read the manifest.json object and all associated CSV data files.
  • When referencing the version ID of your objects, exclusive permissions such as s3:GetObjectVersion are necessary.
  • To successfully run S3 Batch Operations on encrypted objects, you must provide IAM access to the AWS KMS keys associated with those same objects.
