Implementations§

Source§

impl VortexSource

Source

pub fn with_expr_adapter_factory( &self, expr_adapter_factory: Arc<dyn PhysicalExprAdapterFactory>, ) -> Arc<dyn FileSource>

Sets a PhysicalExprAdapterFactory for the VortexSource. Currently, this must be provided in order to filter columns in files that have a different data type from the unified table schema.

This factory will take precedence when opening files over instances provided by the FileScanConfig.
