public static List<ColumnInfo> getUpsertColumnMetadataList(final Configuration configuration) throws SQLException {
    Preconditions.checkNotNull(configuration);
    List<ColumnInfo> columnMetadataList = null;
    columnMetadataList = ColumnInfoToStringEncoderDecoder.decode(configuration);

    }
    final String tableName = getOutputTableName(configuration);
    Preconditions.checkNotNull(tableName);
    final Connection connection = ConnectionUtil.getOutputConnection(configuration);
    List<String> upsertColumnList = PhoenixConfigurationUtil.getUpsertColumnNames(configuration);
    if (!upsertColumnList.isEmpty()) {
        LOG.info(String.format("UseUpsertColumns=%s, upsertColumnList.size()=%s, upsertColumnList=%s ", !upsertColumnList.isEmpty(), upsertColumnList.size(), Joiner.on(",").join(upsertColumnList)));
    }
    columnMetadataList = PhoenixRuntime.generateColumnInfo(connection, tableName, upsertColumnList);
    // we put the encoded column infos in the Configuration for re usability.
    ColumnInfoToStringEncoderDecoder.encode(configuration, columnMetadataList);
    connection.close();
    return columnMetadataList;
}
