**What is Manifest Format?**
A manifest file in AWS S3 replication is typically in JSON format, containing object details like keys, versions, metadata, and replication configurations.
1. **Types of Formats**:
- **JSON Format**: Preferred for its flexibility and ease of serialization, allowing complex data representation.
- **CSV Format**: Less common but viable, especially for simpler use cases or compatibility needs.
2. **Creating Manifest Using S3 Replication**:
- Define replication rules in the source bucket's replication configuration.
- S3 automatically generates and manages manifest files.
- These files ensure objects are replicated according to defined rules and configurations.
