Which statement about caching in Confluence is true?

• A. It reduces database load and improves performance
• B. It always increases memory usage
• C. It eliminates the need for a database
• D. It is disabled by default

Answer: (C)

Caching in Confluence stores copies of frequently requested data in memory or on fast storage so subsequent requests can be served quickly without querying the database. This reduces the number of database queries and speeds up page rendering and other operations, which is why this idea is true. But caching doesn’t eliminate the database—the cache is simply a performance layer that relies on the database for the authoritative data, and it must be invalidated or refreshed when content changes to prevent serving stale information. Memory usage isn’t guaranteed to rise in every case; caches are sized and evictions are used so you can gain faster performance without consuming unlimited memory. In practice, caching is enabled by default to boost performance, and administrators tune its size and behavior as needed.
