+1 (non-binding) I'm glad to see the coming of Dubbo which is a very popular RPC framework.
2018-02-03 19:44 GMT+08:00 Huxing Zhang <hux...@apache.org>: > Dear Apache Incubator Community, > > Please accept the following proposal for presentation and discussion: > https://wiki.apache.org/incubator/DubboProposal > > Dubbo is a high-performance, lightweight, Java based RPC framework. > Dubbo offers three key features, which includes interface based remote > call, fault tolerance & load balancing, and automatic service > registration & discovery. > > Any feedback from the incubator community is much appreciated. > > I've attached the proposal below. > > Best Regards, > Huxing > > = Dubbo Proposal = > > == Abstract == > > Dubbo is a high-performance, lightweight, java based RPC framework > open-sourced by Alibaba. As in many RPC systems, Dubbo is based around > the idea of defining a service, specifying the methods that can be > called remotely with their parameters and return types. On the server > side, the server implements this interface and runs a Dubbo server to > handle client calls. On the client side, the client has a stub that > provides the same methods as the server. > > == Proposal == > > Dubbo has a fairly huge community today, and is widely adopted by many > companies and organizations, but most of them are in China. We believe > running Dubbo in Apache Software Foundation can facilitate development > of a stronger and more diverse community. > > Alibaba submits this proposal to donate Dubbo's source code and its > side projects to the Apache Software Foundation. The code is already > under the Apache License Version 2.0. Dubbo source code and its side > projects are hosted on github right now: > > * Dubbo code base: https://github.com/alibaba/dubbo > * Web site: https://github.com/dubbo/dubbo.github.io > * Documentations: User > Guide(http://dubbo.io/books/dubbo-user-book-en), Development > Guide(http://dubbo.io/books/dubbo-dev-book-en), Admin > Manual(http://dubbo.io/books/dubbo-admin-book-en) > * Other side projects hosted under dubbo group(https://github.com/dubbo) > > == Background == > > Dubbo was developed at Alibaba in 2011 and has been widely used in > many production lines there since then. Dubbo offers three key > features, which include interface based remote call, fault tolerance & > load balancing, and automatic service registration & discovery. Since > Dubbo is open-sourced on github, it's been received up to 15k stars, > and has been forked for more than 10k times. Besides being widely > adopted inside Alibaba, Dubbo is also used in approximately 80% of > internet companies in China, including JingDong(http://www.jd.com), > DangDang(http://www.dangdang.com), Qunar(https://www.qunar.com), > NetEase Kaola(https://www.kaola.com), etc. In 2017, Dubbo has won the > TOP 10 most popular open source projects in China for 2 consecutive > years since 2016. > > We'd like to share this outstanding framework at the Apache Software > Foundation, and start developing a wider community through the Apache > way. We believe more people and organizations can be benefit from it > by doing so. > > == Rationale == > > Remote procedure call (RPC) is one of the cornerstones to build > distributed systems, especially useful in today's e-commercial > industry and cloud computing providers. Dubbo is the java-based RPC > implementation. By using Dubbo, developers can call the remote service > just like call a local method but without worrying about the details > for the remote interaction. We expect more interesting features and > use cases to emerge from the community ranging from microservices to > cloud computing, and many other areas. > > == Current Status == > > === Meritocracy === > > The intent of this proposal is to start building a diverse developer > and user community around Dubbo following the ASF meritocracy model. > Since Dubbo was open sourced, many companies in China adopted Dubbo to > build up their own contributing system, moreover, we received many > enhancements or issue reports from them at the same time. The codebase > is now mainly managed by the development team inside Alibaba who's > responsible for building internal distributed system too. Any > suggestion or issue is discussed on > https://github.com/alibaba/dubbo/issues and more casual talk happens > in gitter channel (https://gitter.im/alibaba/dubbo). We plan to invite > more people as committers if they contribute to this project. > > === Community === > > Dubbo is currently being developed by the development team inside > Alibaba who's responsible for building internal distributed system > too. Since it's open-sourced, Dubbo is widely adopted by many other > companies including CNUCC (China Nets Union Clearing Corporation), > ICBC (Industrial and Commercial Bank of China), China Life Insurance, > DiDi, Qunar, Dangdang, NetEase Kaola, Maoyan Movie, GOME, Haier, CSDC > (China Securities Depository and Clearing Corporation Limited), > AsiaInfo, and many more. We hope to grow the base of contributors by > inviting all those who offer contributions and excel through the use > of The Apache Way. Contributions from outside of Alibaba are > constantly accepted by Dubbo project and its side projects. Right > now, we make use of github as code hosting as well as both Google > Groups and gitter for community communication. > > === Core Developers === > > Dubbo is currently being developed by engineers from Alibaba, > Dangdang, Qunar and WeiDian. Ding Li, Huxing Zhang, Ian Luo, Jun Liu, > Liujie Qin, Mercy Ma, Von Gosling, William Liang are working for > Alibaba. Most of them are working in Alibaba middleware team, and some > of them are also the core members of internal RPC framework, HSF (high > speed service framework). Von Gosling is the co-creator of Apache > RocketMQ, while Huxing Zhang is one of Apache Tomcat PMC members. > Besides, the Dubbo core developers also includes Xin Wang from > WeiDian, Liang Zhang from DangDang, Zhaohui Yu from Qunar. All of them > are in charge of building and maintaining distributed system in their > organizations, and have great passion in contributing back into Dubbo > project. > > === Aligment === > > The ASF is the natural choice to host the Dubbo project as its goal of > encouraging community-driven open source projects fits with our vision > for Dubbo. The ASF is also the home to many other projects with which > we are familiar with and hope to integrate better with Dubbo including > Apache Thrift, Apache Zookeeper, etc. We believe that there will be > mutual benefit by close proximity to these and other projects. > > == Known Risks == > > === Orphaned products === > > The core developers currently work full-time on RPC area for Alibaba. > Dubbo is widely adopted by many companies and individuals. There's no > realistic chance of it becoming orphaned. > > === Inexperience with Open Source === > > The core developers are all active contributors, users and followers > of open source. They are all already committers and contributors to > Dubbo project, and have gained good experience in running open-source > project in Github and interacting with the community. Moreover, Von > Gosling and Huxing Zhang from the initial committer, both are working > on Apache projects (RocketMQ and Tomcat respectively), will guide > others to practice the Apache Way together along with other incubator > mentors. > > === Homogenous Developers === > > The current set of developers work across a variety of organizations > including Alibaba, DangDang, Qunar, and WeiDian. Furthermore, many > other companies forked Dubbo and continued to enhance in their own > private repositories. We plan to encourage them to contribute and > invite them as contributors to work on one common code base. > > === Reliance on Salaried Developers === > > Currently, most of core developers are paid to work on Dubbo project > by Alibaba. We look forward to attracting more people outside Alibaba > to join this project, either payed engineers working on RPC area, or > individual volunteers, as long as they have enthusiasm for the Dubbo > project. > > === Relationships with Other Apache Products === > > Dubbo integrates Apache Thrift as one of RPC protocols it supports, > and Apache Zookeeper as one of service registration/discovery > machanisms. We look forward to collaborating with those communities > and any others which use RPC. > > === A Excessive Fascination with the Apache Brand === > > While we respect the reputation of the Apache brand and have no doubt > that it will attract new contributors and users, our interest is > primarily to give Dubbo a solid home as an open source project > following an established development model. More reasons are provided > in the Rationale and Alignment sections. > > == Documentation == > > A complete set of Dubbo documentations is provided on dubbo.io in both > English and Simplified Chinese. > > * Dubbo user guide: > http://dubbo.io/books/dubbo-user-book-en(English), > http://dubbo.io/books/dubbo-user-book(Chinese) > * Dubbo development guide: > http://dubbo.io/books/dubbo-dev-book-en(English), > http://dubbo.io/books/dubbo-dev-book(Chinese) > * Dubbo admin manual: > http://dubbo.io/books/dubbo-admin-book-en(English), > http://dubbo.io/books/dubbo-admin-book(Chinese) > > == Initial Source == > > Dubbo was initially developed within Alibaba, and then was > open-sourced with The Apache License 2.0 under Alibaba Group on Github > in 2011.
