Which caching strategy will meet these requirements?
Implement a TTL strategy for every item that is saved in the cache.
Implement a write-through strategy for every item that is created and updated.
Implement a lazy loading strategy for every item that is loaded.
Implement a read-through strategy for every item that is loaded.
Explanations:
A TTL strategy might result in stale data if the cache expires before a database update occurs.
A write-through strategy ensures that each update to the database is immediately written to the cache, maintaining data consistency.
Lazy loading only updates the cache when data is read, so there may be stale data until a read request occurs.
A read-through strategy retrieves data from the cache or database on read but does not update the cache on writes, so it may serve stale data.
I weigh that the answer is:
Implement a write-through strategy for every item that is created and updated.
To the best of my knowledge, the answer is:
Implement a write-through strategy for every item that is created and updated.
