Detailed Description

Registry for FileIO implementations.

Provides a mechanism to register and load FileIO implementations by name. This allows the REST catalog (and others) to resolve FileIO implementations at runtime based on configuration properties like "io-impl".

Member Function Documentation

Load()

Result< std::unique_ptr< FileIO > > iceberg::FileIORegistry::Load ( const std::string &  name, const std::unordered_map< std::string, std::string > &  properties  )

static

Load a FileIO implementation by name.

Parameters

name	The implementation name to look up.
properties	Configuration properties to pass to the factory.

Returns

A unique_ptr to the FileIO instance, or an error if not found.

Register()

void iceberg::FileIORegistry::Register ( const std::string &  name, Factory  factory  )

static

Register a FileIO factory under the given name.

Parameters

name	The implementation name (e.g., "local", "s3")
factory	The factory function that creates the FileIO instance.
