thrift

前两天想在微博上发表一个观点：在现在的技术体系中，能用于描述通讯协议的方式很多，xml,json,protobuf，thrift，如果在有如此众多选择的基础上，在设计系统时，还自造协议，自己设计协议类型和解析方式，那么我只能说，您真的落后了，不是技术上，而是思想上。对于xml,和json我们不做过多描述了，参考相关文档就可以了。特别是json，如今在 web系统，页游系统的前后台通讯中，应用非常广泛。 本文将重点介绍两种目前在大型系统中，应用比较普遍的两种通讯框架，thrift和Protobuf ，为什么叫通讯框架，而不叫通讯协议？因为这两种技术，如果仅仅当作协议解析用，对于其强大的功能，就大打了折扣。 对于 两种利器而言，首推的应该是thrift ，因为其不仅有对于协议封装和解析的处理，而且有完备的通讯框架的实现，完全封装了底层通讯 ，对于使用者，只要在框架的客户端和服务器接口回调中，处理逻辑就可以了 。对于其确切的描述，我们还是引用官方的说法吧，这样更准确些，以免由于我自己的想法，影响了大家的理解。 Thrift是一个跨语言的服务部署框架，最初由Facebook于2007年开发，2008年进入Apache开源项目。Thrift通过一个中间语言(IDL, 接口定义语言)来定义RPC的接口和数据类型，然后通过一个编译器生成不同语言的代码（目前支持C++,Java, Python,

Is there one? Is there a simple means of generating Thrift connections? Update: The short answer to this question turns out to be no, there is no JS client for Thrift that is compatible with Cassandra. Further Update: The next release of Cassandra (0.8 at time of writing) is going to have support for an Avro API. There is already node.js module for Avro support. 回答1: Someone made one now: https:/

The root issue (as it turned out) stems from mismatching protocol and/or transport formats on the client-side with what the server-side is implementing, and this can happen with any client/server paring. Mine just happened to be Cloudera and HappyBase, but yours needn't be and you can run into this same issue. Has
