If you ask me why I want to organize this upgrade assistance event,
Then I would say:
-
I don’t want to see you troubled because you don’t have technical support and don’t dare to upgrade because you don’t understand it well!
-
I don’t want to see you struggling and conflicted because you encounter issues with the lower version and have no workaround, so you can only upgrade to solve the problem but are hesitant and waiting!
-
I don’t want to see you eagerly anticipating new features going live, but hesitating back and forth because no one is there to assist during the upgrade!
Therefore, I organized a 20-member Upgrade Mentor Team composed of community moderators, experienced evangelists, and official technical support teachers to help everyone upgrade!
Special thanks to the mentor team: @lalalalala @NameAsPerson @ShawnYan @songxuecheng @xfworld @TIbrother @Jellybean @TiDBer_CQ @h5n1 @Jarry_zhu @WalterWj @HandsomeTian7 @tidbEnthusiast @Jasper @CatSufficient @Kongdom @TiDBLearningPath @DemoErmian @wakaka @FlyingUnderwear
I hope you can be like them too!
Let’s enjoy the happiness brought by the upgrade together:
Very stable, no need to work overtime! You will have time to accompany your wife and children!
Cost reduction and efficiency increase, allowing you to report to your boss with lower operation and maintenance costs because the resource control function can reduce a lot of your costs.
Faster, reducing the waiting time for running data, allowing you to check anytime without worries!
Having said so much! Let’s get straight to the point!

Why Upgrade TiDB?
-
Cost Reduction and Efficiency Increase:
- The new version of TiDB may introduce features for resource control and performance optimization, enabling users to use computing resources more efficiently, thereby reducing operating costs.
- By fixing performance bottlenecks in the old version, the new version can improve the database’s processing speed and throughput, allowing the same hardware resources to handle more business requests.
-
Ease of Use:
- With the update of TiDB versions, the user interface and operation process may be improved, making database management more intuitive and user-friendly.
- The new version may introduce more intelligent monitoring and diagnostic tools, simplifying the process of identifying and solving problems, and improving the ease of use of the database.
-
Ease of Maintenance:
- Improvements in security and stability mean that the frequency of database failures may decrease, reducing maintenance workload.
- Community assistance ensures that even if problems are encountered, users can get timely help and solutions, reducing maintenance difficulty. When the version is too low, the support for surrounding components may not be perfect; too old versions have passed the EOL time, so if you don’t upgrade and encounter problems, you can only bear it yourself because community members can’t help you (everyone no longer has the environment to help you reproduce the problem), see TiDB version support timeline & TiDB version rules
- The documentation and guides for the new version are usually more comprehensive, providing more best practices and examples to help users better maintain and optimize the database.
-
New Features: The new version of TiDB usually introduces new features and improvements that can help users achieve more business needs and enhance application functionality.
-
Stability Enhancement: By fixing issues and bugs in the old version, the new version of TiDB usually provides higher stability and reliability.
