Enum RelationIdType 

pub enum RelationIdType {
    Int32,
    Int64,
    Utf8,
    LargeUtf8,
    Utf8View,
}

Scalar ID types accepted by dense relational operations.

This is deliberately narrower than the set of Arrow integer types. Native cuVS output/gather paths are only defined for these five stable SQL types.

Variants

Int32

Signed 32-bit integer identifiers.

Int64

Signed 64-bit integer identifiers.

Utf8

UTF-8 string identifiers with 32-bit offsets.

LargeUtf8

UTF-8 string identifiers with 64-bit offsets.

Utf8View

UTF-8 identifiers stored as Arrow string views.
