### Feature Request / Improvement Today, long-running writes to PyIceberg risk failing when credentials expire mid-transaction. The Java implementation addressed this by adding a vended-credential refresh mechanism that calls a REST catalog endpoint to obtain new credentials whenever the current ones are within five minutes of expiring. I propose a similar approach for PyIceberg, delivered in three separate PRs: 1. **VendedCredential class implementation** (largest diff) -> PR ready to review 2. **Credential refresh support in `PyArrowFileIO`** -> PR pending review and merge of 1 3. **Credential refresh support in `FsspecFileIO`** -> PR pending review and merge of 1 PRs 2 and 3 depend on PR 1, which provides the core vended-credential implementation. -- This is an automated message from the Apache Git Service.
