How does the database read and write? what is the optimization scheme?

In order to solve this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

The read and write rate of the database depends entirely on the disk read and write rate. Ali Cloud ESC disk mounts can choose SSD cloud disk, efficient cloud disk and ESSD. There is a big difference in price.

Many people are willing to accept mixing and matching to improve performance.

Take Oracle as an example. If you put the data tablespace on the efficient cloud disk and the index tablespace on the SSD cloud disk, the performance will be greatly improved.

Insert update operations can improve at least 20%, and the performance of tables with more indexes may be improved by more than 50%.

Queries will also be improved by more than 50%, as the steps to retrieve the exact location of the data are accelerated.

For system cache (swap swap), you can also specify a high-speed cloud disk to improve part of the performance.

The answer to the question about how to read and write the database is shared here. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
