This article introduces the relevant knowledge of "what is the content of FastDFS design architecture". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Specific content

FastDFS has two core components:

Tracker: responsible for saving all Storage meta-information and information lookup

Storage: real data storage. Theoretically, Storage can be expanded without restriction. Users are not directly involved in storage storage, they just find tracker.

All storage data nodes are described using the concept of groups. A group of storage may contain multiple storage hosts, so if you want to distinguish between groups, you must rely on Tracker.

There is a good data synchronization effect in the concept of each storage group, that is to say, the data of multiple storage hosts in a group are the same, if there is a problem with one of the hosts in the group, then the original storage data will be automatically copied after the host is changed, and the corresponding service will be provided automatically.

In the current system development process, a problem has been obviously found: the shutdown backup operation is very low. Therefore, many Internet companies are more concerned about the security of data, so using these development frameworks can effectively avoid the loss caused by the loss of these data.

This is the end of the content of "what is the FastDFS Design Architecture?" Thank you for reading. If you want to know more about the industry, you can follow the website, the editor will output more high-quality practical articles for you!
