At the very > beginning, Sharding-Sphere is just a JDBC driver for data sharding > (name as Sharding-JDBC) at Dangdang internal framework; now it offers > data sharding, distributed transaction and database orchestration. > Besides JDBC, proxy to implement MySQL database protocol is also > supported at present. Furthermore, our roadmap includes Proxy for > PostgreSQL protocol, Sidecar model, data repica and elastic data > scalability function as well. > > Due to the extension of project, we provide proxy model and sidecar > model in addition to JDBC model. Therefore, we rename it to > Sharding-Sphere by > [[https://github.com/sharding-sphere/sharding-sphere/issues/788|a > public vote]], which refers to a sharding ecosphere with > Sharding-JDBC, Sharding-Proxy and Sharding Sidecar as its three > sub-projects. > > Sharding-JDBC has won the > [[http://www.oschina.net/project/top_cn_2016|TOP 20 most popular open > source projects in China 2016]]. > > = Rationale = > > Relational database still plays a very important role on current > application system. The maturity of products and surrounding > ecosystem, the friendliness of its data query and developers' and > DBAs' mastery of it, cannot be completely replaced with other types of > database in the near future. However, current relational database > cannot support cloud native very well and it is not friendly to > distributed system. > > It is the ultimate goal of Sharding-Sphere, which manages the > databases scattering around the system, to make user use distributed > databases as simply as using a single one. > > Without extra cost, Sharding-JDBC directly connects database with Java > application to get the best performance. > > Sharding-Proxy is deployed as a stateless server and supports MySQL > protocol at present. In the paper > [[https://db.cs.cmu.edu/papers/2016/pavlo-newsql-sigmodrec2016.pdf|What’s > Really New with NewSQL?]], three types of NewSQL are introduced, among > which Sharding-Proxy is a Transparent Sharding Middleware. > > Sharding-Sidecar can be understood as a data panel in Service Mesh. > The interaction between the application and the database provides a > mesh layer. The concept of Database Mesh is similar to Service Mesh, > and it focuses on how to connect data access applications to the > database. Database Mesh will set up a huge grid system between > applications and databases. Applications and databases need be placed > in the grid system. They are all objects managed by the meshing layer. > > = Current Status = > == Meritocracy == > Sharding-Sphere was incubated at Dangdang in 2015 and open sourced on > GitHub in 2016. In 2017, Jingdong recognized its value and determined > to sponsor this project. Sharding-Sphere has contributors and users > from many companies; we have set up the PMC Team and Committer Team. > New contributors are guided and reviewed by existed PMC members. When > they are ready, PMC will start a vote to promote him/her to become a > member of PMC or Committer Team. See the details See the details > [[http://shardingsphere.io/community/en/organization/|here]]. > Contributions are always welcomed and highly valued. > > == Community == > Now we have set development teams for Sharding-Sphere respectively in > Jingdong, Dangdang and Bestpay. Companies like Sohu and Dataman have > shown great interest in Sharding-Sphere. We hope to grow the base of > contributors by inviting all those who offer contributions through The > Apache Way. Right now, we make use of github as code hosting as well > as gitter for community communication. > > == Core Developers == > The core developers, including experienced open source developers and > team leaders, have formed a group full of diversity. > > = Known Risks = > == Orphaned products == > Three development teams from Jingdong, Dangdang and CHINA TELECOM > Bestpay will spare no pains to work on Sharding-Sphere in the future > with contributors from the growing community. Also, Sharding-Sphere is > widely adopted in China by many > [[http://shardingsphere.io/community/en/company/|companies and > organizations]]. Thus, it is very unlikely that Sharding-Sphere > becomes orphaned. > > == Inexperience with Open Source == > > The current core developers all work for companies that have developed > or contributed to many open source projects. > > * Liang Zhang, PMC. He is the lead of two open source projects, > Sharding-Sphere and Elastic-Job. Also Committer of Apache Dubbo > (Incubator). > > * Sheng Wu, PMC.

Also contribute a lot of features of > Elastic-Job. > > Therefore, we believe we have enough experience to deal with open source. > > == Homogenous Developers == > The current core developers work across a variety of organizations > including Jingdong, Dangdang and CHINA TELECOM Bestpay; some > individual developers are accepted as core developers of > Sharding-Sphere as well. Considering that Sohu and Dataman have shown > great interest in Sharding-Sphere, we plan to encourage them to > contribute and invite them as contributors to work together. > > == Reliance on Salaried Developers == > At present, three of the core developers are paid by their employer to > contribute to Sharding-Sphere project. It is estimated that the > development of Sharding-Sphere will be continued with mainly salaried > developers, and we will make efforts to attract more volunteers and > grow the community. > > == Relationships with Other Apache Products == > > An automatic prober of Sharding-Sphere is introduced into SkyWalking > to send APM data, and SkyWalking also use Sharding-Sphere to persit > tracing data. Saga provided by ServiceComb is adopted by > Sharding-Sphere as one of the distributed transaction processing > engines. Sharding-Sphere integrates Apache Zookeeper as one of the > service registration/discovery mechanisms. > > == A Excessive Fascination with the Apache Brand == > We acknowledge the value and reputation that the Apache brand would > bring to Sharding-Sphere.
