Which is faster, redis or mysql?

Overall, Redis is faster than MySQL because it uses a key-value pair data structure, which is stored in memory and is suitable for storing small data that needs to be retrieved quickly. MySQL uses a relational database model, which is stored on the hard disk and is suitable for storing large, structured data that requires relational queries.

Speed ​​comparison of Redis and MySQL

Get straight to the point:
Overall , Redis is faster than MySQL in most cases.

Cause analysis:

1. Data structure

• Redis uses key-value pair data structure, while MySQL Use a relational database model.
• The key-value pair structure is simpler and faster to find and retrieve data.

2. Memory usage

• Redis stores data in memory, while MySQL stores data on the hard disk.
• Memory access is much faster than hard disk access.

3. Usage scenarios

• Redis is ideal for storing small data that needs to be retrieved quickly, such as caches, sessions, and counters.
• MySQL is suitable for storing large, structured data that requires relational queries.

Specific example:

• For simple key-value retrieval, Redis can handle hundreds of thousands of requests per second.
• For complex relational queries, MySQL can provide fast and accurate results.

Conclusion:

Redis is a better choice when fast data access is required. MySQL is more suitable when you need to store large amounts of structured data.
