VariantLogicalType#

public enum VariantLogicalType#

Logical type identifiers returned by VariantUtils.getVariantTypeId(ColumnView).

These values mirror the explicitly assigned numeric values of the experimental C++ cudf::io::parquet::experimental::variant_logical_type enum. The IDs are part of the Java API contract and must not be derived from the Java enum ordinal.
