This article shows you the use of Elastic certified engineers, the content is concise and easy to understand, it can definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

1. Many people say that Elastic certified engineers are useless

Others will say:

Then what is the use of this certificate? Is to use $400 to prove that you are good?

Don't you have a good understanding of es during the interview? And es is just one of the technologies we need to master.

I haven't heard what certificate is required for doing skills.

My view has always been: like CET-4 and CET-6, it is useless to pass!

Did not pass CET-4 and CET-6, you said useless, mostly guilty, some of my classmates and friends, took the exam for many years, at most more than 10 times, but CET-4 or CET-6, while comforting themselves: useless, enterprises do not look at this, focus on participation!

I have roughly discussed and analyzed the root cause: I have not mastered the method! (it goes too far)

Elastic certification is the same truth, useless, but as an Elastic enthusiast, passed the exam said that your mind will be very calm, down-to-earth!

2. Is TM useful or not?

it differs from man to man.

First: it is useful for the rapid construction of knowledge system!

Second: useful for comprehensive familiarity with official documents!

Third: useful for solving online problems in actual combat! (when you encounter relevant technical problems, you basically don't need to turn to the community for help, and more than 80% of the problems can be solved by yourself. )

Fourth: useful for strengthening confidence and overcoming fear in English!

One more thing here, people in the community and the planet often ask if there are any books or documents in Chinese.

I have to say that all the Chinese books on the market have the lag of technology.

People who are proficient in English reading skills actually have the advantage of pre-emptive strike.

You can see this by looking at the more awesome senior engineers and architects around you.

3. For whom is the Elastic certification exam useless? First: a shuttle usage user.

No matter three, seven, twenty-one, write the code first, and then solve the problem.

Know the "hammer" principle? Isn't it just adding, deleting, changing and checking? That's the only thing about ES. How can it be so mysterious as you say?

Elasticsearch is a shuttle. Let's use it.

Second: pseudo-diligent learners who show their progress in moments!

Muddle through life, every day seems to be very busy, but also working overtime, in fact is to do a lot of useless work.

It doesn't matter. I'll do as much work as the company pays me.

What certification do you take? Don't worry about other people's affairs.

Third: people who can't stick it out.

I want to dabble in all the new technologies, but I can't stick it out for all kinds of reasons.

As a result, a hammer in the east and a hammer in the west spend a lot of time digging countless shallow wells!

4. What are the good qualities of those who have passed the exam?

First: learn the technology in a down-to-earth manner and work steadily. Clocking in near the wee hours of the morning in the certification circle is proof!

Second: be good at communication. Find, raise and solve problems in communication.

Third: go to school and help downwards.

In addition to studying by yourself, I am also willing to solve the problems raised by other friends in the group.

After years of practice, you will find that standing in other people's business scenarios and solving other people's problems is actually one of the fastest ways to overtake around corners. Because it's like you're doing it again. Note: the usage of the word "you"!

If the same problem occurs for the second and third time, and you are happy to solve it, you have become an expert in the field of subdividing knowledge points. This is the shortcut, seemingly stupid, but absolutely effective.

Fourth: there is no way out. Once you decide to sign up for the exam, it is a spur to yourself.

If you take a step forward, you will master the skills and improve yourself.

Take a step back, leaving endless regret, lost a lot of confidence and courage!

In particular, I was moved to see that the ball players worked hard in the case of the dissolution of the company and passed the certification examination in less than two months. I'm sure he will find a job in a big factory. His hard work confirms a sentence-"it's not because I'm strong, but because I have no choice!"

People are doing it, heaven is watching. God will give you a corresponding reward for every effort you make.

If there is no return, it is just not time, please wait a little longer, continue to persist and work hard!

5. How to improve after passing the certified engineer?

I've said it many times before. Passing doesn't mean it's good.

It is still a long way from the bosses of the big factories, including some of the bat bosses of the planet.

First: the passage only means that the foundation is relatively solid. Pay attention to the word "relative".

Second: the underlying principle of Elasticsearch needs to be further improved through practice.

Third: the underlying principles of Lucene need to be further studied and improved.

Fourth: the source code of ES and Lucene needs to be further studied and improved.

Fifth: the actual combat design ability, architecture ability, problem-solving ability need to be further improved by practical learning.

Sixth: the principle of search engine is improved in further practice.

Seventh: ELK periphery: kibana, logstash, beats, etc., and related big data systems: Hbase, spark, flink, chickhouse,kafka and other real-time computing and analysis technologies with further integration and integration.
