Question

I have using PropertyGraphIndex. How can I save and load PropertyGraphIndex from AWS s3?

To save and load a PropertyGraphIndex using AWS S3, you can follow these steps:

Saving to S3

1. Set up S3FS: Ensure you have the s3fs package installed and configure it with your AWS credentials.

2. Save the Index:

   import s3fs
   import os
   
   # Set up s3fs
   AWS_KEY = os.environ["AWS_ACCESS_KEY_ID"]
   AWS_SECRET = os.environ["AWS_SECRET_ACCESS_KEY"]
   R2_ACCOUNT_ID = os.environ["R2_ACCOUNT_ID"]
   
   s3 = s3fs.S3FileSystem(
      key=AWS_KEY,
      secret=AWS_SECRET,
      endpoint_url=f"https://{R2_ACCOUNT_ID}.r2.cloudflarestorage.com",
      s3_additional_kwargs={"ACL": "public-read"},
   )
   
   index.set_index_id("property_graph_index")
   index.storage_context.persist(persist_dir="llama-index/storage_demo", fs=s3)

Loading from S3

1. Load the Index:

   from llama_index.core import StorageContext, load_index_from_storage
   
   index_from_s3 = load_index_from_storage(
      StorageContext.from_defaults(persist_dir="llama-index/storage_demo", fs=s3),
      index_id="property_graph_index",
   )

Ensure you have the necessary S3 permissions (s3:ListBucket, s3:PutObject, s3:GetObject) to perform these operations ^[1].

Why do I need R2_ACCOUNT_ID here?

[dosubot[bot]]

The R2_ACCOUNT_ID is needed to construct the endpoint_url for the S3-compatible storage service. This URL is essential for s3fs.S3FileSystem to connect to the correct storage endpoint, as shown in the setup example:

s3 = s3fs.S3FileSystem(
    key=AWS_KEY,
    secret=AWS_SECRET,
    endpoint_url=f"https://{R2_ACCOUNT_ID}.r2.cloudflarestorage.com",
    s3_additional_kwargs={"ACL": "public-read"},
)

This ensures that the connection is made to the right storage service ^[1].

Can I do it without R2_ACCOUNT_ID?

[dosubot[bot]]

Yes, you can configure s3fs.S3FileSystem without the R2_ACCOUNT_ID if you're using standard AWS S3. You would simply omit the endpoint_url or set it to None:

s3 = s3fs.S3FileSystem(
    key=AWS_KEY,
    secret=AWS_SECRET,
    endpoint_url=None  # Use None for standard AWS S3
)

This setup will connect directly to AWS S3 without needing a custom endpoint URL ^[1].
