Subject Re: [DISCUSS] Sharding-Sphere incubation proposal
Date Fri, 02 Nov 2018 15:58:43 GMT
Thanks to Sharding-Sphere team. 


My introduction:

The company I worked for and the company I’m working for are using Sharding-Sphere. And
the Sharding-Sphere is one of the SkyWalking’s OAP storage implementation. 

So, I think I can help so more, whether coding or community.

> = Abstract =
> Sharding-Sphere is an ecosystem of transparent distributed database
> middleware, focusing on data sharding, distributed transaction and database
> orchestration. It provides maximum compatibility for applications through
> Sharding-JDBC (a driver to implement JDBC) or Sharding-Proxy (a proxy to
> implement database protocol).
> 
> = Proposal =
> With a large number of end users, Sharding-Sphere has a fairly huge
> community in China. It is also widely adopted by many [[
> http://shardingsphere.io/community/en/company/|companies and
> organizations]] as a solution to process their massive amounts of data.
> 
> We believe that bringing Sharding-Sphere into Apache Software Foundation
> could advance development of a stronger and more diverse open source
> community.
> 
> Dangdang submits this proposal to donate Sharding-Sphere's source codes and
> all related documentations to Apache Software Foundation. The codes are

> = Background =
> 
> Relational database hardly supports such huge amounts of data any more
> which has increased rapidly in recent years, but for reason of technique
> maturity, developers and DBAs still want to use it to persist core data.
> 
> Sharding-Sphere was open sourced on Github in 2016. 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
