How does Spring cacheable work?
Spring Cache uses the parameters of the method as key and the return value as a value in the cache. When the method is called the first time, Spring will check if the value with the given key is in the cache. It will not be the case, and the method itself will be executed.
Which annotation is responsible for triggering the cache population with the required data?
@Cacheable
For caching declaration, the abstraction provides a set of Java annotations: @Cacheable triggers cache population. @CacheEvict triggers cache eviction.
Why we use cacheable true in LWC?

Why is cacheable true in Salesforce?

How do I override the @cacheable key in spring?
Any data stored in a cache requires a key for its speedy retrieval. Spring, by default, creates caching keys using the annotated method’s signature as demonstrated by the code above. You can override this using @Cacheable’s second parameter: key.
