Incremental Dataset Versioning for LLMs with S3

Question

Pulumi · Accepted Answer

When you want to implement incremental dataset versioning for large language models (LLMs) using Amazon S3, you are essentially looking to create an S3 bucket on AWS which allows for the versioning of objects. This is particularly useful when dealing with LLMs, as the datasets used for training such models can be very large and change frequently. Having the ability to revert to or access previous versions of these datasets is critical for experiments and audits.

To set this up, we'll need to:

1. Create an S3 bucket to store your datasets.
2. Enable versioning on that S3 bucket to keep track of changes and allow for access to older dataset versions.

Here's a Pulumi program that accomplishes just that:

```python
import pulumi
import pulumi_aws as aws

# Create an S3 bucket to store your dataset
bucket = aws.s3.Bucket("llm-dataset-bucket",
    # Define bucket configuration as needed, for example, setting the ACL to private
    acl="private"
)

# Enable versioning on the S3 bucket to keep track of changes to the datasets
# and allow retrieval of older versions
# For more information, see the documentation: https://www.pulumi.com/registry/packages/aws/api-docs/s3/bucketversioningv2/
bucket_versioning = aws.s3.BucketVersioningV2("llm-dataset-versioning",
    bucket=bucket.id,  # Link the versioning configuration to our bucket
    versioning_configuration={
        "status": "Enabled"  # By setting this to 'Enabled', versioning is turned on for the bucket
    }
)

# Export the name of the bucket
pulumi.export("bucket_name", bucket.id)
# Export the name of the bucket versioning configuration
pulumi.export("bucket_versioning_status", bucket_versioning.versioning_configuration.apply(lambda v: v["status"]))
```

In this program, we import the necessary modules from Pulumi's AWS SDK. We first create a new S3 bucket that will hold the datasets. We set the access control list (ACL) of the bucket to `private` to ensure that the data is not publicly accessible.

After creating the bucket, we proceed to enable versioning by using the `BucketVersioningV2` resource from the `pulumi_aws` module. Through the `versioning_configuration` property, we set the `status` to `Enabled`. This ensures that every change to an object in the bucket will create a new version, which can then be retrieved as needed.

We also export the name of the bucket and the status of the versioning feature using Pulumi's `export` function. The `.apply()` method is used to transform the nested value within the output, allowing us to just get the `status` from the `versioning_configuration`.

By running this Pulumi program with `pulumi up`, you will provision the necessary AWS S3 infrastructures that are set up for incremental dataset versioning, which is a foundation for effectively managing data for LLMs.
