How does Cloudflare R2 differ from AWS S3?

Cloudflare R2 is S3-compatible but charges zero egress bandwidth fees, making it significantly more cost-effective for applications with high data retrieval rates.

Can I use existing S3 SDKs with Cloudflare R2?

Yes, R2 supports the S3 API. You can use standard AWS SDKs for JavaScript, Python (Boto3), and the AWS CLI by updating the endpoint to your R2 account URL.

What is Sippy migration?

Sippy is an incremental migration tool that copies objects from S3 to R2 on-demand as they are requested, allowing you to migrate data without paying massive upfront egress charges.

What is the benefit of using R2 with Cloudflare Workers?

R2 provides a native Workers binding that allows for low-latency, high-performance storage operations directly on the Cloudflare edge without managing API keys.

Does R2 support multipart uploads?

Yes, R2 supports multipart uploads for files up to 5TB. This skill includes implementation patterns for handling large files (>100MB) efficiently.
