Enum CatalogBackendType 

#[non_exhaustive]
pub enum CatalogBackendType {
    Parquet,
    External(String),
}

Catalog backend used to satisfy runtime data catalog requests.

Serializes as its name, so an external backend round-trips as the plain factory name that registered it, matching WriterBackendType.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
