public class BaseUserDefinedTableMacro extends org.apache.calcite.sql.validate.SqlUserDefinedTableMacro
Druid-specific version of SqlUserDefinedTableMacro which copies & overrides a bunch of code to handle string array arguments. Would be best if Calcite handled such argument: retire this class if we upgrade to a version of Calcite that handles this task.
