Heavy weight · elasticsearch7.x learning Roadmap

1、 Why sort out the learning roadmap ?

Paying attention to Elastic The Chinese community 、QQ Group 、 In the process of the cluster , More or less, there will be some basic problems . And these problems are not complicated , Most of them are mentioned in official documents , A little more complicated in the official English community 、 There have been similar discussions in the Chinese community .

Basically through Google、bing You can search for answers directly or indirectly .

So the question is : Why many new friends , I can't find the answer .

I watched and thought for a long time . I think the main problem is , It's not established Cognition of the whole picture of basic knowledge .

As the saying goes “ Standing higher 、 To see further ”, To be free from the details , Look at the problem from the whole rather than the part , Only by analogy , Find the underlying cause of the problem faster , And then solve the problem .

And sort out the knowledge points through mind mapping , It's about building the whole picture Faster One of the ways .

therefore , That's why this article .

2、Elasticsearch7.X Learning Roadmap

3、 How to solve the problem ?

First of all : Find the answer from the large and complete official English documents , Instead of looking for... From scattered translated articles .
because : Many friends have complained about being biased by some one-sided information , And suddenly looking back , The official answer has long been clear .

Premise : Have a thorough understanding of the overall situation and details of the chapters in the official documents .

second : More hands-on verification , Not what I thought .
What you think is not necessarily right ,“Talk is cheap. Show me the code." Practice is to make “ I thought ” The only way to shut up .
The skills acquired in practice will form in the long run “ Muscle memory ’, It's not easy to forget .
such as :logstash Of grok Analytical problem .

Third : Use... Correctly Google、Stackoverflow、Elastic English community 、Github issues、Elastic The Chinese community .
Correct English key words You can get twice the result with half the effort .

Always believe in : I'm not a big cow , All the problems I have encountered are a piece of cake , Daniel has already met , And we've given a great solution ; Even the lower version didn't solve , Higher version ES It's all planned .

give an example :Elasticsearch6.7+ The emergence of ilm Index Lifecycle Management Visualization configuration function .

Fourth : Log level errors , Check the source context if necessary .
Suggest : combination Elastic Source code analysis book , Enhance global awareness , Quick to understand .

The fifth : In addition to the official suggestions, we should check some underlying information .
such as : Principle of writing 、 Query principle 、 Index allocation principle 、 Routing principle, etc .

Alibaba cloud 、 Tencent cloud's deep blog suggests reading .

There is a problem , Welcome to . Let's make progress together !
