File Transport between Server/Client

梦想的初衷 提交于 2019-12-01 21:11:49
What kind of Service should I define for ".thrift"-file to use it later for my Program? This File Transport should be between the Client and the Server and it should be "partly". StreamFileService.thrift: struct FileChunk { 1: binary data 2: i64 remaining } service StreamFileService { FileChunk getBytes(1:string fileName, 2: i64 offset, 3: i32 size); } StreamFileClient.java: public class StreamFileClient { private int fileChunkSize = 16; private String filePath; public String getFilePath() { return filePath; } public void setFilePath(String filePath) { this.filePath = filePath; } private void

Loop through specific resource files in maven to generate sources

﹥>﹥吖頭↗ 提交于 2019-12-01 13:49:31
I use maven-antrun-plugin to generate sources from thrift IDL. I have a separate project (and jar) to hold these generated sources and this plugin does not support wildcard replacement, so I cannot say *.thrift. I use execution tasks to generate the sources and copy them to src directory. I have the following plugin defined <plugin> <artifactId>maven-antrun-plugin</artifactId> <executions> <execution> <id>generate-sources</id> <phase>generate-sources</phase> <configuration> <tasks> <mkdir dir="target/generated-sources" /> <exec executable="${thrift.executable}" failonerror="true"> <arg value="

how can I define a map accept different kind of value in thrift?

风流意气都作罢 提交于 2019-12-01 13:42:10
I define a struct with thrift: struct QuerySetRecord { 1:string recordId, 2:string crawlerName, 3:string recordType, 4:map<string,string> dataMap, 5:i16 priority, } the problem is the dataMap , I do not only want to accept string value, I may still want to accept List or Map , such as map<string, list<string>> dataMap . In other words, I want a type like the root Object in Java, object in python Can I do this? You would have to create your own Object and list all possible classes in it. union Object { 1: string str; 2: i32 number32; } (as I'm not sure how union implementation works in all

thrift中使用list数据类型传输大数据瓶颈及解决方案

感情迁移 提交于 2019-12-01 12:36:39
董的博客中thrift相关基础的介绍:http://dongxicheng.org/search-engine/thrift-rpc/ thrift碰到大list时瓶颈的原因: 因为thrift协议中server和client的交互使用的是序列化的数据。当你使用thrift --gen cpp **.thrift 产生一个符合你使用场景的数据结构时,该数据结构都会对应了thrift中的相应的序列化的结构来序列化它。对于list类型数据结构的序列化thrift分三部: 体现在write_virt函数的调用上,第一次写入1,第二次写入2,第三次8。如果你的list数据长度为一千多万,那么每个都对应了一个write_virt,每个write_virt都有响应的memcpy操作,这个是很耗时的。 解决方案: 把list这种结构的数据进行序列化,使用thrift传输binary类型的数据,这样便可以解决thrift序列化list慢的问题。因为thrift对binary类型的数据序列化使用的是整块拷贝,不像list是分块拷贝。 其中将list序列化的部分我使用的是boost的序列化方式。 有关数据序列化的问题我使用的是boost的序列化方式 boost序列化使用方面比较不错的文章: IBM讲解序列化的方法:http://www.ibm.com/developerworks/cn/aix

十万个为什么之SOA服务,服务治理,微服务

安稳与你 提交于 2019-12-01 11:11:03
SOA与服务治理 SOA: 面向服务的体系结构 (SOA) 是一项引人注目的技术,用于开发与业务模型保持最佳一致性的软件应用程序。 服务治理: 也称为SOA治理,指的是用来管理SOA的采用和实现的过程。 SOA(面向服务的体系结构)概念由来已久,在10多年前便开始进入到我们广大软件开发者的视线中。SOA是一种粗粒度、松耦合服务架构,服务之间通过简单、精确定义接口进行通讯,不涉及底层编程接口和通讯模型。SOA可以看作是B/S模型、Web Service技术之后的自然延伸。 服务治理要点 服务定义(服务的范围,接口和边界) 服务部署生命周期(各个生命周期阶段) 服务版本治理(包括兼容性) 服务迁移(启用和退役) 服务注册中心(依赖关系) 服务消息模型(规范数据模型) 服务监视(进行问题确定) 服务所有权(企业组织) 服务测试(重复测试) 服务安全(包括可接受的保护范围) SOA服务落地 (dubbo的实践使用) 直到2011年10月27日,阿里巴巴开源了自己的 SOA服务化治理方案的核心框架Dubbo ,服务治理和SOA的设计理念开始逐渐在国内软件行业中落地,并被广泛应用。 Dubbo是一个高性能服务框架,致力于提供高性能和透明化的RPC远程服务调用方案,以及SOA服务治理方案,使得应用可通过高性能RPC实现服务的输出和输入功能,和Spring框架可以无缝集成。 作为一个分布式服务框架
