**Which part is this question about** `object_store` crate. **Describe your question** The `AmazonS3Builder` implements its own AWS credentials resolution and provisioning (which currently doesn't support ECS environments natively). AWS SDKs (see [here](https://github.com/awslabs/aws-sdk-rust/blob/d1962fd42d376c5c695877041d2a269fd1fa50cd/sdk/aws-config/src/default_provider/credentials.rs#L25) for the Rust SDK) feature a well defined Credential Provider Chain. My question is: why does this project not use the official AWS Rust SDK implementation for credentials (and possibly the S3 client implementation)? **Additional context** Issue apache/arrow-rs#4283 should fix credentials resolution for ECS runtime environments. However the fix doesn't work, since the provided metadata_endpoint is still used in the context of the EC2 credentials provider which postfixes a `/latest/api/token` path, which breaks credentials resolution for ECS: https://github.com/apache/arrow-rs/blob/77aa8f5b2645a91724048f5c1d644c6b52880028/object_store/src/aws/credential.rs#L429 -- This is an automated message from the Apache Git Service.
