Thrift和CQL 3列/行之间的区别 [英] Difference between Thrift and CQL 3 Columns/Rows

问题描述

在Cassandra峰会上，有人提到Thrift和CQL 3在列和行的定义上有微妙的差别。 Google并没有帮助我理解这种差异。我可以找到的唯一信息是元数据是不同的，因此，我不应该混合thrift和CQL。

1. 什么是


2. 以什么方式破坏兼容性？


3. 为什么




我很高兴阅读任何有助于我的文档，我已经无法找到任何东西

解决方案

这是我教授的回答这个问题的阅读路径：



1. Apache Cassandra 1.2简介


2. Thrift to CQL3升级指南


3. CQL3 for Cassandra专家：DataStax


4. CQL是否支持动态列/宽行？






At the Cassandra Summit, it was mentioned that Thrift and CQL 3 have subtle differences in their definitions of columns and rows. The Google hasn't helped me understand this difference. The only information I can find is that the metadata is different, and as such, I shouldn't mix thrift and CQL.

1. What is the subtle difference (I've read a bit about metadata representations...)?
2. in what way does it break the compatibility?
3. Why is the change better?

I'm happy to read any docs that will help me, I've just been unable to find anything specifically related to this topic.

解决方案

Here's the reading path I was taught to follow to answer this same question:

1. Intro to Apache Cassandra 1.2
2. A Thrift to CQL3 upgrade guide
3. CQL3 for Cassandra experts : DataStax
4. Does CQL support dynamic columns / wide rows?
