- Add aws_access_key_id, aws_secret_access_key, aws_session_token, and region_name parameters - Pass credentials through to S3StorageAdapter and boto3.client() - Enables multi-tenant scenarios with different AWS accounts - Maintains backward compatibility (uses boto3 default credential chain when omitted) - Add comprehensive tests for credential handling - Add examples/credentials_example.py with usage examples Fixes credential conflicts when multiple SDK instances need different credentials. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

"""Example: Using explicit AWS credentials with DeltaGlider.
|
|
|
|
This example demonstrates how to pass AWS credentials directly to
|
|
DeltaGlider's create_client() function, which is useful when:
|
|
|
|
1. You need to use different credentials than your environment default
|
|
2. You're working with temporary credentials (session tokens)
|
|
3. You want to avoid relying on environment variables
|
|
4. You're implementing multi-tenant systems with different AWS accounts
