public class AlterTableMetadataRequest extends Object implements org.apache.avro.generic.IndexedRecord
A set of parameters for GPUdb.alterTableMetadata.

      Parameters:
      tableNames - Names of the tables whose metadata will be updated, in [schema_name.]table_name format, using standard name resolution rules. All specified tables must exist, or an error will be returned.
