pub struct VortexSource { /* private fields */ }
Expand description
Execution plan for reading one or more Vortex files, intended to be consumed by DataSourceExec
.

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