In this issue, Xiaobian will bring you about how to achieve worm replication in mysql. The article is rich in content and analyzes and narrates from a professional perspective. After reading this article, I hope you can gain something.

Worms replicate, as the name suggests, by replicating themselves, and multiply--exponentially. The mysql worm is all about replication.

How to understand the concept of mysql worm replication?

Simply put, we will already exist in a data table in the data content, query out and then copy to the specified another data table, this operation is called worm replication.

Then the worm replication step is to find out the data first, and then will find out the new data again.

For example, when we need to replace the data table, we can use worm replication to query the data in the data table through the select statement, and then copy it to the new data table. Of course, the method of replacing the data table can usually be directly imported and exported.

So in most cases, mysql worm replication is used for mysql testing, test data!

We can understand this because mysql worm replication causes data to multiply exponentially.

So we can test the stress and efficiency of the table by worm replication, which causes the table to generate a lot of data, that is, expand to a certain order of magnitude.

Basic syntax for worm replication:

insert into + table name + field list/* + from table name;

Here are some simple summaries:

mysql worm replication:

Copy data from an existing data table to a new data table;

2, can quickly let the data in the table expand to a certain order of magnitude, more used to test the pressure and efficiency of the table.

The above is how to achieve worm replication in mysql shared by Xiaobian. If there is a similar doubt, please refer to the above analysis for understanding. If you want to know more about it, please pay attention to the industry information channel.
