Javaで大規模なフォームデータのバッチ操作を処理するにはどうすればよいですか?

public void insertBatch(List<FormData> formDataList) {
    Connection conn = null;
    PreparedStatement pstmt = null;
    try {
        conn = DBUtil.getConnection();
        conn.setAutoCommit(false);
        String sql = "INSERT INTO form_data (name, age, gender) VALUES (?, ?, ?)";
        pstmt = conn.prepareStatement(sql);
        for (FormData formData : formDataList) {
            pstmt.setString(1, formData.getName());
            pstmt.setInt(2, formData.getAge());
            pstmt.setString(3, formData.getGender());
            pstmt.addBatch();
        }
        pstmt.executeBatch();
        conn.commit();
    } catch (SQLException e) {
        e.printStackTrace();
        if (conn != null) {
            try {
                conn.rollback();
            } catch (SQLException ex) {
                ex.printStackTrace();
            }
        }
    } finally {
        DBUtil.closeConnection(conn, pstmt);
    }
}

public void processData(List<FormDate> formDataList) {
    ExecutorService executorService = Executors.newFixedThreadPool(10);
    for (FormData formData : formDataList) {
        executorService.submit(new ProcessDataTask(formData));
    }
    executorService.shutdown();
    try {
        executorService.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
}

private class ProcessDataTask implements Runnable {
    private FormData formData;

    public ProcessDataTask(FormData formData) {
        this.formData = formData;
    }

    @Override
    public void run() {
        // 处理表单数据的耗时操作
        // ...
    }
}
