Best practices for queries and indexing
It would be difficult to write the best queries for reference and reuse. It will always vary based on the nature of your application, architecture, design, table structure, and so on. However, precautions can be taken while writing MySQL queries for better performance, scalability, and integrity.
Let's go through a few of the best practices that we should keep in mind while designing or writing MySQL queries.
Data types
A database table could consist of multiple columns with data types, such as numerics or strings. MySQL 8 provides various data types rather than just limiting to numerics or strings:
- Small is good. As MySQL loads data in memory, a large data size would have an adverse impact on its performance. Smaller sets can accommodate more data in memory and reduce overheads of resource utilization.
- Fix your length. If you don't fix the data type length, it would have to go and fetch the required information each time it needs to. So, wherever it's...
