aliyun TableStore相关操作汇总
tableStore更新时，必须有PK
总结：
这个东西本身可能技术还不成熟，使用的人少，有问题很难解决
遇到的问题：
（1）没有一个GUI工具，使用门槛高
（2）查询的GetRange不方便，把查询出来的数据使用System.out.println打印出来的是乱码
（3）batch insert时报错及解析：
表格存储Table Store限制项：https://help.aliyun.com/knowledge_detail/38573.html
BatchGetRow 一次操作请求读取的行数 不超过 100 N/A
BatchWriteRow 一次操作请求写入行数 不超过 200 N/A
BatchWriteRow 一次操作的数据大小 不超过 4 MB N/A
GetRange 一次返回的数据 5000 行或者 4 MB 一次返回数据的行数超过 5000 行，或者返回数据的数据大小大于 4 MB。以上任一条件满足时，超出上限的数据将会按行级别被截掉并返回下一行数据主键信息
一次 HTTP 请求 Request Body 的数据大小 不超过 5 MB
