    Builder table = InMemoryRecordSet.builder(METADATA);
    for (String catalog : filter(listCatalogs(session, metadata, accessControl).keySet(), catalogFilter)) {
        QualifiedTablePrefix prefix = FilterUtil.tablePrefix(catalog, schemaFilter, tableFilter);
        for (Entry<SchemaTableName, List<ColumnMetadata>> entry : listTableColumns(session, metadata, accessControl, prefix).entrySet()) {
