LoadEqualityDeletes()

Result< std::unique_ptr< UncheckedStructLikeSet > > iceberg::DeleteLoader::LoadEqualityDeletes	(	std::span< const std::shared_ptr< DataFile > >	delete_files,
		const StructType &	equality_type
	)		const

Load equality deletes into an in-memory set.

Parameters

delete_files	Equality delete files to load (must have content == Content::kEqualityDeletes)
equality_type	The struct type describing the equality columns

Returns

A StructLikeSet containing the deleted rows

LoadPositionDeletes()

Result< PositionDeleteIndex > iceberg::DeleteLoader::LoadPositionDeletes	(	std::span< const std::shared_ptr< DataFile > >	delete_files,
		std::string_view	data_file_path
	)		const

Load position deletes for a specific data file.

Reads the given position delete files and returns a PositionDeleteIndex containing only the positions that apply to the specified data file path. Supports both regular position delete files and deletion vectors.

Parameters

delete_files	Position delete files to load (must have content == Content::kPositionDeletes)
data_file_path	Path of the data file to filter positions for

Returns

A PositionDeleteIndex with deleted positions for the data file
