Enum SchemaProfile 

pub enum SchemaProfile {
    Homogeneous {
        column_count: usize,
        kind: BuilderKind,
    },
    Mixed,
}

Schema profile for processor optimization.

Classifies schemas as homogeneous (all columns same type) or mixed to enable specialized processing paths.

Variants

Homogeneous

All columns share the same type.

Fields

column_count: usize

Number of columns in the schema.

kind: BuilderKind

The common builder kind for all columns.

Mixed

Columns have different types.
