AWS S3

We have tested extensively with the following SDK's

• Node.js

npm install @aws-sdk/client-s3 @aws-sdk/s3-request-presigner

• Python

pip install boto3>=1.34.0

• Rust AWS S3 SDK

# Cargo.toml S3 sdk
aws-sdk-s3 = { version = "1.72.0", features = ["behavior-version-latest"] }

It is expected that all existing client SDKs available for all languages, are compatible with Flashback API, for the supported API operations.

This is thanks to S3 authentication mechanism based on HMAC signatures.

Given the right credentials, any S3 client SDK can generate the correct request or pre-signed URL signature, and the signature can be validated by the Flashback Endpoint against the API key, without any external intervention or the need of an authentication endpoint.

The only requirement to use S3 client SDKs on Flashback nodes is indicating the endpoint URL you want to use, and use one of the valid repo generated API keys.
