	Optional list of historical table schemas for field lookup.
std::shared_ptr< Schema >	projected_schema
bool	case_sensitive = true
std::shared_ptr< NameMapping >	name_mapping
	Optional name mapping for files written without field IDs.
std::unordered_map< std::string, std::string >	properties
	Format-specific or implementation-specific options for data readers.
bool	apply_residuals {false}

Detailed Description

Options shared by all tasks opened by this reader.

Member Data Documentation

apply_residuals

bool iceberg::FileScanTaskReader::Options::apply_residuals {false}

Whether to enforce each task's residual filter row by row, after deletes and before final projection. Residuals are bound against projected_schema; invalid references and unsupported expressions return errors.

case_sensitive

bool iceberg::FileScanTaskReader::Options::case_sensitive = true

Case sensitivity for residual binding and reader field name resolution. Must match TableScan::is_case_sensitive(); tasks do not carry this setting.

projected_schema

std::shared_ptr<Schema> iceberg::FileScanTaskReader::Options::projected_schema

The read and output projection; this need not be the full table schema. Must be a projection of table_schema. With apply_residuals enabled, callers must include every field referenced by each task's original residual, even if binding would fold its predicate to a constant. Open() fails on missing references rather than adding fields from table_schema. Filter-only columns remain in the output; delete-only columns are added internally as needed and removed before returning batches.
