What exactly is materialized about class org.apache.drill.exec.record.MaterializedField?
The name gave me the impression that it would be a field/column with its data materialized (as a materialized view has copies of data). However, MaterializedField doesn't seem to contain data values (just field metadata like the name/pathname and data type). So what exactly does the class represent? (What's materialized, and relative to what?) Daniel -- Daniel Barclay MapR Technologies
