Cnosdb Nirvana Rebirth: abandon go and fully embrace rust

CnosDB Amos in the community , You must have found it recently , be based on Rust Version of CnosDB Isipho Has switched to GitHub master station , And the community team no longer maintains and supports Go Version of CnosDB. First of all, I would like to extend my sincere apology to you , The haste of previous plans and decisions has brought unnecessary trouble to everyone . But with a responsible attitude towards the community , Here I also give you a detailed explanation ： Why do we give up Go, hug Rust To build a new time series database . 

CnosDB Isipho What is it?

CnosDB Isipho It's based on Rust R & D time series database , High performance 、 High compression ratio 、 High availability features , And in the future, it will meet the requirements of distributed cloud native . from 2022 year 3 Month begins ,CnosDB The team began to GitHub In the open source Isipho Source code , And continue to build the system .CnosDB Isipho Committed to solving the problem of timeline inflation 、 With super large-scale time series support and better ecological characteristics . About CnosDB Isipho Characteristics and collective function structure , You can refer to CnosDB Isipho Road map ：cnosdb/README.md at main · cnosdb/cnosdb · GitHub

be relative to Go,Rust Is a better database development language

First version of CnosDB Selected Go As a development language , At that time, I thought Go It can deal with the balance between ease of use and system performance , But as for Go A deep understanding of language , We also found that Go Language is written in database system , Especially in the compilation of time series database .

Go The main problems are ：Go runtime It brings GC It will cause performance jitter , And the time series database needs to be extremely stable in a heavy load environment ;Go Support for generics is also bad , Language expression ability is limited , If you need to better operate resources , The requirements for developers are very high . our Go The performance evaluation of this version is not significantly better than the existing head products .Go There are still many problems to be solved in version , In order to meet the challenges brought by cloud Nativity , Better service, better enterprise cloud ,Go Version requires large-scale refactoring of the original version , In order to ： Improve distributed scalability and achieve the final consistency model ; Improve the ability of operation and maintenance free ; Improve storage and query performance ; Support multi tenancy at the same time , Cloud native .

When we are troubled by Go The problems caused by language ,CnosDB Of Isipho The team is already Rust It has been working for nearly five months . be relative to Go Language ,Rust It has the following characteristics ：Rust nothing GC, More precise memory control , High hardware compatibility ;Rust Support the paradigm match expression , More expressive ;Rust Higher reliability , Various errors can be found during compilation . Developer pair Rust My love is also beyond words .

With Rust Applications in the field of basic software are also booming , even to the extent that Linux And start using Rust Refactoring the system kernel （ Linus Torvalds is cautiously optimistic about bringing Rust into Linux kernel's next release | ZDNet）, And more and more database vendors are trying to use Rust To implement the system , We also firmly believe that , Use Rust It can build a better time series database to serve customers .

Why give up Go edition

For an open source community organized by a startup team , Maintain products of two different technology stacks at the same time , Very difficult ; It is also difficult for teams to communicate and manage effectively . The development team has been working hard for two quarters with the technology stack fragmented , And we have observed signs of division in our community , Some amateurs tend to Go Study and use of version , And more developers flock to the community because of our Rust Version and its courses ：《 Use Rust Construct a TSDB》.

As mentioned above , Time series database is making great strides towards cloud native ecosystem , stay Go Version, such as multi tenancy 、 Cloud native and other functions , It's almost pushing the original code down and starting over .Rust The version is going well , Let's choose not to continue running blindfolded on the wrong road , But made a difficult choice , give up Go Language version , And put all the development strength of the company into Rust Version development , Deliver better next-generation temporal database products to communities and users .

Now? ,CnosDB Isipho Version of the storage engine has been built , The development team is fully developing the query engine and index function , It is planned to bring the stand-alone version before the end of this year CnosDB Isipho. meanwhile ConsDB We also sincerely hope that the time series database 、 Yes Rust Interested amateurs join CnosDB Community , Contribute code or become a full-time developer . Community activities will not decrease , Everyone is looking forward to CnosDB Isipho At the same time , We continue to launch rich content , Including but not limited to chaos engineering courses and Rust Follow up courses .

It starts with the interconnection of all things , Open source across five continents . I hope you will continue to pay attention to and support CnosDB！

CnosDB brief introduction

CnosDB It's a high performance 、 High usability open source distributed time series database , It has been officially released and fully open source .
