我遇到更诡异的问题，MemoryClassLoader 这个类提示 ClassNotFound ...

springboot 环境遇到同样问题了

I find the cassandra's table definition : ``` **primary key (partition, adapter_id, sort, data_id, vis, nano_time, field_mask, value, num_duplicates)** ``` Any way to custom this ?

> Thx for your reply, Where can i find the `sort keys` ? My situation is that: The data written twice is just **the same**
