 @NonNull String ioImplClassName,
 @NonNull Map<String,String> properties)

Description copied from interface: FileIOFactory

Loads a FileIO implementation for server-side use (metadata read/write, purge).

This method may obtain subscoped credentials to restrict the FileIO's permissions, ensuring secure and limited access to the table's data and locations.

storageAccessConfig is authoritative for credentials and storage-config extras. properties may carry catalog-trusted contextual settings (for example table-default.*). Callers must not pass table metadata.properties(), which can include caller-controlled FileIO client settings such as s3.endpoint.

Specified by:

loadFileIO in interface FileIOFactory

Parameters:

accessConfig - the storage access configuration containing credentials and other properties.

ioImplClassName - the class name of the FileIO implementation to load.

properties - catalog-trusted contextual properties for the FileIO.

Returns:

a configured FileIO instance.
