使用python多线程，运行时自定义线程数，自动计算每个线程处理的数据量，连接mysql读取数据，处理成需要的字段入到elasticsearch。
运行效果图：
10个线程 运行会在这里实时刷新，方便查看每个线程处理到的id数：[root@localhost shw]# python put_album.py
{"0": "2105success ", "1": "196723success ", "2": "392557null", "3": "587819null", "4": "782519null", "5": "977482null", "6": "1172186null", "7": "1366897null", "8": "1561614null", "9": "1754368success "} "}
