Cassandra：SSTableLoader使用什么协议？
[英]Cassandra: what protocol used in SSTableLoader?
问题描述
Imho, there are 2 available protocols to connect client app to cassandra server: CQL and thrift. 
Imho，有两种可用的协议可将客户端应用程序连接到cassandra服务器：CQL和Thrift。
What protocol used by SSTableLoader utility to load sstables to cassandra cluster? SSTableLoader实用程序使用什么协议将sstables加载到cassandra集群？ As I understand it does not use CQL because it is impossible to do bulk loading with good performance via CQL. 据我了解，它不使用CQL，因为不可能通过CQL进行具有良好性能的批量加载。
If thrift then the question is: how it uses thrift for bulk loading? 如果是节俭的，那么问题是：如何使用节俭进行批量装载？

Yep, thrift is used . 是的，使用节俭 。
it is impossible to do bulk loading with good performance via CQL
Not really true, its just that the functionality has already been implemented and there's no reason for re-implementing it in CQL because thrift wont be getting dropped (allows for good backwards compatibility) 并不是真的，只是功能已经实现，没有理由在CQL中重新实现它，因为节俭不会被丢弃（允许良好的向后兼容性）
To sum it up, the sstables are read in, a thrift client is created for streaming said data and then a LoaderFuture task is created to coordinate the streaming. 总而言之，读入稳定表，创建节俭客户端以流传输所述数据，然后创建LoaderFuture任务以协调流传输。
