Structs
Broke out into multiple message types so that type metadata did not need to be in separate message All types that are of the empty message types contain no additional metadata about the type
Useful for representing an empty enum variant in rust E.G. enum example{One, Two(i32)} maps to message example{ oneof{ EmptyMessage One = 1; i32 Two = 2; } }
logical expressions
logical plan LogicalPlan is a nested type
a node containing data for defining values list. unlike in SQL where it’s two dimensional, here the list is flattened, and with the field n_cols it can be parsed and partitioned into rows
Enums
Contains all valid datafusion scalar type except for List
