This article is shared from Huawei cloud community “Reveal those things behind The Ten-million-level transactions of Maimaimaimaimaimaimai.com”, the original author: Huawei cloud headlines.
On the cloud general mobilization of dry goods, take you together to reveal those things behind buy buy!
From ancient times to the present, our trade and consumption process
Earth-shaking changes are taking place
Today, Yunbao wants to bring us
Unlock the story behind buying, buying and buying for thousands of years
Looking back to ancient times
People realize their consumption needs by bartering
But often because of the unequal value of goods and unhappy parting
Then came money, from shells to copper coins
“Buy, buy, buy” is possible, but money is hard to carry around
Trading becomes a heavy burden
In the Song Dynasty, paper money was handed in, which greatly improved trading efficiency
However, the problem of “counterfeit banknotes” has plagued people for thousands of years
Now, the development of Internet technology
Let online payment permeate every corner of our life
Transactions can be paid with a swipe of a code
But those of you who are cautious must have
The earliest online shopping, buyers have appeared successful orders
I paid for it but didn’t get it
The seller got the complaint but no record of the order
You eat a bad review and you have no reason to
What the hell is going on here?
Yunbao will take you to micro services
Worried about payment special
But before we understand the problems of modern trading
Let’s take a look at the following three
Q1: What are transactions?
A transaction is a logical processing unit composed of a group of SQL statements. It can be regarded as a large activity composed of different small activities. They have four properties, the transaction ACID property:
Atomicity
Consistency
Isolation
“Durability”
Just keep that in mind
They all succeed or they all fail
There is no “Schrodinger’s transaction”
Q2: What are distributed transactions?
After a single application is split into multiple applications, an SOA architecture, or microservice architecture, is formed. At this time, it becomes a distributed system, and the transactions generated by the distributed system are distributed transactions.
Rowed a point
Ordinary transactions in a singleton architecture are not split due to applications
All functions mixed together, pull the whole body
However, distributed transactions under microservices architecture are due to application splitting
Each system has a clear division of labor and cooperation
Q3: Why are distributed transactions needed?
To give you a typical distributed transaction scenario ~
The whole e-commerce shopping involves four systems
Initiate transactions from the order system
If in the process of ordering
The warehouse system does not end up generating outgoing records
The inventory system should eliminate the deduction
The integration system should also be eliminated
TA can maintain data consistency
Avoid the occurrence of “tragedy” between buyer and seller
Data out of sync
Distributed transactions make data consistent ▼
I’d like to recommend it to you
