RowSignatures

public static final class RowSignatures.ComplexSqlType
extends org.apache.calcite.sql.type.AbstractSqlType

Calcite RelDataType for Druid complex columns, to preserve complex type information. If using with other operations of a RelDataTypeFactory, consider wrapping the creation of this type in RelDataTypeFactory#createTypeWithNullability(RelDataType, boolean) to ensure that if the type factory is a {@link org.apache.calcite.rel.type.RelDataTypeFactoryImpl} that the type is passed through {@link org.apache.calcite.rel.type.RelDataTypeFactoryImpl#canonize(RelDataType)} which interns the type. If {@link SqlTypeName} is going to be {@link SqlTypeName#OTHER} and a {@link RelDataTypeFactory} is available, consider using {@link #makeComplexType(RelDataTypeFactory, ColumnType, boolean)}. This type does not work well with {@link org.apache.calcite.sql.type.ReturnTypes#explicit(RelDataType)}, which will create new {@link RelDataType} using {@link SqlTypeName} during return type inference, so implementors of {@link org.apache.druid.sql.calcite.expression.SqlOperatorConversion} should implement the {@link org.apache.calcite.sql.type.SqlReturnTypeInference} directly for best results.
