Java EE 8 Design Patterns and Best Practices

When to use the cache-aside pattern

It is recommended that the cache-aside pattern is used when data isn't updated frequently, or when concurrent updates are infrequent. It is important to note that the cache-aside pattern should only be used when necessary. This is because the cache increases the complexity of applications, as dirty readings involving data definitions can sometimes occur. With this in mind, we recommend that you only apply this pattern if reading data is a slow process.
