+## Bucket-Level Configuration
+
+The Native S3 FileSystem supports per-bucket configuration overrides, allowing
different S3 buckets to use different connection settings within the same Flink
cluster. This enables scenarios like:
+
+- **Checkpointing to one bucket** with specific credentials
+- **Savepoints to another bucket** with different region/endpoint
+- **Data sinks to third-party buckets** with cross-account IAM roles
+
+### Format
+
+Bucket-level configuration uses the format:
`s3.bucket.<bucket-name>.<property>`
+
+Bucket names containing dots (e.g., `my.company.data`) are fully supported
through longest-suffix matching.
