Question 1

What is the difference between cache clean and cache flush in Magento 2?

Accepted Answer

Cache clean removes only invalid or outdated entries and keeps valid cache. Cache flush clears the entire cache storage and forces a full rebuild.

Question 2

Should I use cache clean or cache flush?

Accepted Answer

Use cache clean for routine work and minor changes. Use cache flush for major updates, or when clean does not resolve an issue.

Question 3

Does cache flush cause downtime?

Accepted Answer

Not downtime, but it can briefly slow the store while the cache rebuilds, which is why a cache warm up afterward helps.

Question 4

What is the command to clear Magento 2 cache?

Accepted Answer

Use php bin/magento cache:clean for a clean, or php bin/magento cache:flush for a full flush, from the Magento root directory.

Question 5

What is cache warm up in Magento 2?

Accepted Answer

Preloading the cache with frequently visited pages after a flush, so the first real visitors do not hit slow, uncached pages.
