Last year I interviewed a senior engineer of the rear end of time, to see his resume reads "proficient RPC framework," so I ventured to ask him a few questions of principle aspects, such as, "probably at the core of said RPC framework principle "," describe the sequence of the portion of the logic. "
But we chatted for a long time, I found that he did not actually cooked, his answer basically telling me how to use, and how to better make good use of these frameworks. Then, I asked to, "Without RPC framework, how do you want to call interface on another server it."
This problem can be deep or shallow, but especially the test of basic skills of candidates, will be able to thoroughly understand the basic deep thought about whether the candidate RPC framework of principles. Speaking of RPC, I believe you just had to be sure there will be a slight contact with the large body of the company.
Up from the technical complexity, it is not that simple. You go on a recruitment site to see, as long as it comes to jobs PRC framework for the development of basic infrastructure in the sector, and the salary is not low. This fight is below a lot of FIG JD, salary range of 30K ~ 60K.
RPC is really hard to do? I can say with certainty that, at least, this technology is not simple. If you can get to know the design principles RPC framework, or can create their own out of a wheel, then I can at least determine your basic ability is certainly not bad.
If you have the opportunity to participate RPC governance of the company, and is able to solve problems online, you should be able to ability and capacity of senior architect's quite a lot.
This is so, because you are master RPC related technical process, will certainly come into contact with serialization, compression algorithms, protocols, dynamic agency, service registration, encryption, network programming, connection management, health monitoring, load balancing, elegant Kai shutdown, abnormal retry, knowledge of the business groups and limiting fuse and so on.
If you can get these issues, and that ability, how could poor it? Having said that, I also thought of the iceberg model is often brought us. Part above the surface of the water, we look pretty simple. But note that it is something other people after packaging. Those techniques under the water, is the key to our growth.
If you want to completely get to know the RPC, recommended to "you this handwritten achieve ten million traffic infrastructure necessary RPC framework Video";
the way this video with graphics, a variety of application scenarios, principles, practice of combining, RPC explain these very thorough hands-on experience
Content setting to "the gradual deepening" approach to design, to lay a solid foundation with your system knows RPC communication process must know will be of knowledge; and then take you to learn the key and difficult RPC, including management functions RPC framework and cluster management and so on; and finally learn and use, focus on system performance, online troubleshooting and so on.
Watching this video, you will have these benefits:
- RPC master the core principles of architecture and design points
- 20+ high frequency solve problems based on real scenarios
- RPC-depth analysis of system application framework
- Hands-on design a flexible framework for RPC
I want to say
Although the epidemic is serious, but it is his time. Better to take advantage of this time to do some real upgrade their thing.
RPC's knowledge can be said that the interview will ask, where I will share out this video for free, to help a friend want to learn, backstage private letter I, or click here to receive a free! ! !
Better than you people do not terrible, terrible is harder than you good people than you!
Fast acquisition mode :( point here ) free access! Full of sincerity! ! !
