Modeling essays series 124 a simple coding method

explain

Make an extension based on the three bit coding method mentioned above , In this way, we can flat code in a relatively simple way .

After constructing the processing and analysis system with microservices , Naturally, we will encounter the problem of differential naming . Now suppose we need to monitor all running microservices , Real time data usage redis Storage , Log data usage mongo Storage .

How to code so that we can quickly locate the corresponding variables , Instead of looking in the document ？

The three bit coding principle was mentioned before , That is to say, the passing depth is 3 The coding of can accurately distinguish and express the keys we want to find . But this definition needs to be expanded , If the service business is 「 Outside 」, Then our service is 「 Inside 」.

Coding is not just for internal , Also include outside . So it should be expanded to 2X3 In the form of .

for example ： A business project A1, There is a sub business below A2 Of A3 Indicators are through internal projects B1 The following functions B2 Service , There is B3 Under the index , The value is Value.

Then the complete code is A1.A2.A3.B1.B2.B3:Value. Each of them A perhaps B They are all composed of alphanumeric and underlined . More information can be expressed by underlining , for example B3_int, Indicates that this indicator is an integer value .

As we go AB Test You can also quickly view different results through this coding method ,A1.A2.A3.*, It can be said that , This is a business level statistical observation .
