The 17 year growth route of Zhang Liang, an open source person, can only be adhered to if he loves it

When one is in a state of continuous pursuit and sharp thinking , What value and freedom will he gain ？

Some people say , Programmers who have typed 10000 lines of code , You can write a basic entry Guide , It is a reference for beginners . Programmers who code more than 100000 lines , Be able to write an advanced technical manual , For people who are caught in the bottleneck of development “ Point one or two ”. And completed nearly ten million lines of code “ Top players ”, There is no need to carry out tedious “ Narrator biography ”, Its existence itself , It will bring strong positive incentives and value enlightenment to the public .

Zhang Liang introduced to you today , It is what we describe , Written nearly ten million lines of code “ Divine player ”. When focusing on participating in the construction of open source projects , Zhang Liang submitted a total of 9,138,592 Line code .2372 In the day , Zhang liang “ Sit still ”, The average contribution is nearly every three days 10,000 Line code . In the persistence day after day , Submit... Every day 3、4 Sub code is a must in Zhang Liang's personal life , Even more punctual than the daily three meals 、 high frequency .

Huge data , Compare with the industry , It's amazing creativity . Mental strength , Compare with all living beings , There are very few .

Talk about the supporting force behind it , Zhang Liang summed it up in eight words ：『 Because of love , So diligence .』 This love has supported him to experience role switching again and again ： From an ordinary developer to the creator of the world's top open source projects , And then to become a startup company CEO. Seventeen years , Zhang Liang's role is constantly improving , What remains unchanged is his initial enthusiasm and intention to devote himself to the open source industry . For Zhang Liang , The 20 inch display in front of him not only builds a multidimensional world that allows him to enjoy his enthusiasm and advantages , A huge picture about the history and future development of the open source industry has also quietly formed in his eyes ...

One 、 Practice in the code world 『 Perfectionism 』 Pursue elegant code , It's learning , It's art

In Zhang Liang's code world , Elegant code constitutes a beauty of order , It is he who pursues in the code world 『 Perfectionism 』 Main methods .

idea ： Use elegance as “ technology ” Give the soul

Students who are familiar with Zhang Liang know ,『 grace 』, It's the word he has been talking about . The project architecture should be elegant 、 The program should run gracefully 、 The look and feel of the code should be more elegant .

But at first, Zhang Liang was not an advocate of elegant code . Set the time back to more than ten years ago ,21 In the early years of the century , The creativity of programmers is far from being stimulated , Most of them are step-by-step , Take the written lines of code as tools to realize functions , As for design spirituality 、 Readability , It's impossible to talk about .

But the truth is , For development , Ensure the legibility of the code while realizing the simplicity of the code 、 Easy to maintain and expand , This is knowledge 、 Also art . Code is more than just a tool to implement requirements , It is also the embodiment of understanding and abstraction of the business field .

How elegant code should be interpreted ？ What kind of code is excellent and elegant ？ In the reading 《 Clean code 》 when , Zhang Liang found the answer ：

• Elegant code is like military regulations , Strict and orderly , Require software engineers to be organized , Need a clear rule bottom line ;

• Elegant code is hierarchical 、 Clear thinking , The abstraction level of code is required to be the same ;

• Elegant code can be decoupled between modules , And the relationship is clearer ;

• Elegant code needs to be minimalist .

“ Make the code beautiful ”, It's not just about comments 、 Format and other visual effects . There are still many details to consider , For example, whether the variable name is obtained properly 、 Whether the division of rights and responsibilities between classes and functions is clear, and so on . Beyond details and attitude , It will also test whether a developer has strong overall architecture design ability . Is the architecture design reasonable , Whether the functional branches are balanced , Are important factors that test the elegance of a project itself .

But it is not easy to practice elegant code in projects , How to measure the elegance of the code in the project ？ How to keep the overall elegance and robustness of the project ？ These also start with why we should participate in open source . Because only in the open source ecosystem , To maximize the value of elegant code , It is also related to whether the code written by developers can match the higher-level open source ecosystem .

grope ： Trial and error in the open source community

Human growth 、 mature , It needs time and practice . Before growing into a top player in the open source circle , Zhang Liang experienced a trial and error 、 The process of continuously optimizing yourself .

In the past , Enterprises often form several typical chimney business architectures around different businesses , Programmers will only serve their own chimney . This leads to the non opening of codes between departments , Because there is no need to show it to outsiders , Furthermore, developers lack the motivation to write documents . At the same time, because the functions within the enterprise are not interconnected , There are many tools with overlapping capabilities . therefore , In order to make technology in the industry 、 Free flow between fields , The collaboration between teams is closer and tacit , Reduce the repeated work of making wheels , We need a platform or community to undertake such capabilities , Allow developers to submit new functional branches at any time , Add richer features and functions , Form an open source code culture , Create a better engineer atmosphere .

This is the meaning of participating in open source .

When Zhang Liang was still in college, he learned for the first time in the practical programming course Apache Tomcat when , He has a strong interest in open source . When we see that the world's top projects are arranged into neat typefaces and written into textbooks , When forming a neat and elegant beauty , A desire springs up in Zhang Liang's heart ：“ I also want to write something that can be selected into the textbook 、 Software popular all over the world .”

Therefore, Zhang Liang believes , Technical people should have more sober judgment and cognition , Instead of sticking to real conditions and traditional paths , We should think from a higher dimension , Reconstruct a network architecture that better matches the infrastructure . This is Zhang Liang facing the open source field , The first step to successfully build top open source projects in the future .

In terms of technical value , Find an accurate anchor for your personal development . This anchor point , It must conform to the industry 、 Industry development trend , In order to make open source projects have a longer life cycle and broader development space .

Anchor point ： Rewrite the infrastructure for distributed architecture

at that time , It coincides with the high-speed explosion of China's Internet . Pursue elegant code on one side 、 Polish your own technology , While striving to share the technological value with more people , Zhang Liang is also keenly aware of the emergence of the real world “ Discordant vibrato ”—— At that time, the Internet world was mostly a traditional centralized data architecture , But it is increasingly difficult to match with the domestic realistic environment that is developing at a high speed .

With the continuous expansion of online application scenarios , The process of database fragmentation is accelerating , Database architecture 、 agreement 、 function 、 Applicable scenarios are becoming more and more diverse . In terms of database architecture , The centralized database evolved from the stand-alone system coexists with the original distributed oriented new generation database ; In terms of database protocol ,MySQL and PostgreSQL These two main open source ecosystems and the ecosystem provided by manufacturers also occupy a place in the database system ; Each database has more and more unique functions and applicable scenarios .

therefore , Fragmentation has become the general trend in the field of database , The database of a single category cannot be applied to all scenarios , It can only be applied to one or several good scenes .

Therefore, we need to start from actual combat , Match the demand of Chinese Internet , The advantages and uniqueness of creating open source projects . It is against this background , The era will open source 、 Elegant code is bound with Zhang Liang .

Two 、 Open the open source universe “ The gate of honor ” from “ The first one works hard ” To “ To win ”

The process of incubating open source communities , It is also Zhang Liang's personal precipitation 、 Broaden your horizons 、 The process of opening the pattern .

From the initial 3 Modules have grown to today 220 A module , Become Apache The road of honor for top projects ,ShardingSphere I have been walking for seven years . The story goes back to the original starting point , from ElasticJob To Sharding-JDBC Until then ShardingSphere. Seven years , The open source project led by Zhang Liang has experienced a development process from no one cares about it to a little famous and then to shine . All iterations , They are all polished by diligent thinking and a lot of reconstruction .

In the operation of open source projects , Zhang Liang with a firm will , Spend a lot of time 、 Put your energy into the project . Seven years , Zhang Liang is right ShardingSphere Carry out continuous grinding 、 restructure . stay ShardingSphere Within the community , The amount of code contributed by Zhang Liang once reached 80% above . With ShardingSphere Growth along the way 、 The transformation of 、 upgrade , Zhang Liang's understanding and cognition of the open source world has also changed ：『 After open source , How to make the whole project run stably for a long time ？』

“ The reputation of a successful open source project belongs to the community , There is an essential difference between a mature community and an individual's open source project .”

Open source is not a personal game , Several small projects have been unknown since they first set foot in open source , To ElasticJob Preliminary results , Until then Sharding-JDBC Evolve into Apache ShardingSphere And grow into a world-class open source project . Zhang Liang understands , If you want to do a good open source project , Let the project flourish , Then the best way is to gather community forces . You can be the founder of this project 、 Is the leader , But it can't be the only owner .

When I first entered the open source community , Zhang Liang will pay close attention to comments from others , Because it's common to get flushed with a function ,『 perfect 』 It's a word he often talks about . But sometimes , I think it's perfect , But in others' eyes “ Not enough practical ”.『 One thousand thousand , Even in the same scene , Everyone's understanding of functions and requirements is also different . A project belonging to one person , And projects belonging to the community , There are essential differences 』.

The difference is that , The upper limit of individual projects is restricted by individual ability , The depth and breadth of its development , It all depends on the technology and vision of the original author . But from a macro perspective , Open source projects belonging to the community , If you want to have a very high development limit , Rely more on the community 『 multifarious 』 Scenarios and requirements . Zhang Liang thinks that ,“ Accept and welcome the diverse voices of the community , And effectively select constructive voices ” It is a way for open source projects to achieve substantial growth 、 The necessary process to make the open source community stronger . At the level of personal spirit , The source of Zhang Liang's sense of achievement is also changing ： From the dominant spirit of ownership gradually stabilized , Instead, the pattern is higher 、 The family spirit with a broader vision .

With the enthusiastic participation of global technology geeks , Now ShardingSphere It has basically become an indispensable part of programmers' use , Its functions are more widely used 、 Its user base also shows an exponential growth trend . For the current ShardingSphere Come on , The project just caught up with the opportunity of the Internet explosion in China ,ShardingSphere The functions match the development needs of China's Internet . Because it is infrastructure oriented , It can be said that ShardingSphere It is the background database of Internet enterprises 『 Just need to 』, This is also ShardingSphere The uniqueness of .

After years of grinding and testing ,ShardingSphere stay Apache The foundation comes from “ seed ” Grow into “ Hand down disciples ”, The vitality of the community has also become stronger after joining the foundation ,ShardingSphere The community has gradually become a global developer 、 Technology geek 、 Open source enthusiasts and others collide with each other . The community is for all right ShardingSphere Interested people provide open technology 、 The same conversation and common enthusiasm , Become a global exchange stronghold across time and space .

3、 ... and 、 In the business quadrant Build a for global technicians “ Dazzling stage ”

There is no shortage of excellent and intelligent developers in China , But what is lacking is an environment that allows developers to continue to work hard , And the cornerstone of a stable project .

Zhang Liang thinks that , Excellent open source projects are similar to classic dramas . The value of classic drama will be performed by different actors 、 In a surprising breakthrough after breakthrough, time-honored . Its charm will be passed on from generation to generation , Call on people to participate at the behavioral level , It also resonates with everyone at the spiritual level .

It is with this original intention , Zhang Liang plans to work in his beloved open source field , For the global technical people to build a can sprinkle enthusiasm 、 Give full play to your talents “ stage ”.2021 Beginning of the year , With the efforts of Zhang Liang and many founders ,SphereEx The company came into being . The company uses open source projects ShardingSphere Based on , oriented B End customers provide professional business solutions .“ Open source and business are not mutually exclusive . On the contrary , The two can promote each other's development in a more complementary way , Open source can bring a solid user base to commercial companies , And business can also feed open source , So as to establish a more perfect 、 Friendly community ecology .”

From a pioneer in the open source field to an entrepreneur who actively accepts the baptism of business and capital examination , In the face of this change , Zhang Liang admitted that entrepreneurship has expanded his ability boundary ：“ When I act as ShardingSphere When the project leader , It's more about playing the role of Technology Manager ShardingSphere Think and make decisions in top-level design , More inclined to product thinking . When my identity is SphereEx Business operators , I think more about how to design the transfer SphereEx Sustainable business model , How to make a reasonable balance between customer demand and market demand . The founders and technology managers of the company focus on different things , Technology managers focus on code quality and product architecture design , And company managers will pay more attention to cash flow 、 revenue 、 Business strategy 、 Team building, etc .”

Facing the treacherous business circles , Zhang Liang said that although entrepreneurship is challenging , But in the process of commercial operation of the company , His original intention of loving the open source industry and the excitement generated when facing challenges have not changed . From technology to business , In fact, it's like upgrading to a different scene , Trump cards can be used in all situations . Zhang Liang thinks that , No matter what kind of scenario you are facing , The important thing is to have a structured thinking .“ First of all, you need to have the ability of static architecture , This requires you to have a global perspective , Only in this way can we design a suitable and complete underlying structure . On the other hand , You should also have a vision of dynamic architecture , Only in this way can we be flexible with the changes of the real environment , Make the static structure more dynamic .”

In the field of love , People will willingly give themselves “ Set rules ”, And stick to it . There is no such rule , He will not be himself .

For Zhang Liang , Devote 100% enthusiasm and energy to the open source field , Is willing to set up for themselves for many years 、 And stick to it 、 Stick to it “ The rules ”.

On the open source journey , Zhang Liang always follows the call of love in his heart , With a steady stream of courage and perseverance , Continue to move forward on the road of open source ： Experienced several project refactoring 、 The bitterness of transformation ; After nearly ten years of technical study 、 The dormant period of accumulation ; I have also tasted the reality of bearing a huge amount of code of nearly ten million lines alone ... but , After the storm , He also gained beyond his personal perspective , Bigger 、 Enrich 、 Multidimensional value and freedom .

A passionate pursuit of personal interests 、 Fight side by side with like-minded friends 、 Let the vision in your heart be realistic “ Perfect landing ”、 Let personal value be infinitely magnified through global collaboration , And feed back the value 、 Benefit everyone .... These realistic levels of achievement , It forms the colorful scenery on Zhang Liang's way to Kaiyuan .

For Zhang Liang , Love of open source , It's an endless process . And the open source universe is brighter 、 A vast future , Just like Zhang Liang , Persistent pursuit of open source 、 Unique thinking and unlimited love of open source people in the joint construction , Come slowly .
