The MyBatis second-level cache can be used in the following scenarios:
- In scenarios where the query frequency is high and data doesn’t change often, caching the query results in a second-level cache can help improve query performance.
- In scenarios where multiple sessions need to share the same data, using a secondary cache can prevent redundant database queries and improve system performance.
- Reducing the database workload: In high concurrency situations, the database can become a bottleneck for the system. By utilizing secondary caching, the database workload can be reduced, thereby enhancing the system’s ability to handle concurrent processes.
It is important to note that the secondary cache is suitable for read operations on data. For write operations on data, you need to manually refresh the cache or set the cache to read-only mode to ensure data consistency. Additionally, the use of the secondary cache also requires attention to the cache invalidation strategy to avoid dirty reads or the use of expired data.
