# Rationale for this change
This PR introduces support for multi-part namespaces, enabling more flexible
and organized data layouts. This feature allows users to structure their tables
within nested hierarchies (e.g., `('database', 'schema', 'table')`), which is a
common pattern in many data warehouse systems.
The level of support varies depending on the underlying catalog
implementation. Here's a summary of the changes:
| Catalog Implementation | Multi-Part Namespace Support | Notes
|
| ---------------------- | ------------------------------ |
----------------------------------------------------------------------- |
| REST Catalog | ✅ Yes | Fully supports
multi-part namespaces as defined by the REST spec. |
| DynamoDB Catalog | ✅ Yes | The namespace is
represented as a composite key. |
| File Catalog | ✅ Yes | Namespace parts
are mapped to directory hierarchies in the file system. |
| In-Memory Catalog | ✅ Yes | Supports
multi-part namespaces for testing purposes. |
| Hive Catalog | ❌ No | Spark and Hive
Metastore do not support multi-part namespaces. |
| Glue Catalog | ❌ No | Uses AWS Glue
databases which do not support multi-part namespaces. |
