Struct RequiredProperty 

pub struct RequiredProperty {
    pub name: Arc<str>,
    pub column_id: Option<i32>,
    pub data_type: Option<DataType>,
    pub schema_version: u64,
}

Carries resolved metadata so that scan operators and storage cursors no longer rely on alias/name heuristics. The schema_version binds the identity to a specific catalog generation, preventing stale reuse after schema changes.

Fields

name: Arc<str>

Property name (column name in storage).

column_id: Option<i32>

Resolved column index in the target ColumnStore, if known.

data_type: Option<DataType>

Data type from schema binding.

schema_version: u64

Schema version at binding time.
