What are Redis Cache Tags in Laravel?

They're labels on cached data letting you flush groups precisely—no more TTL waits or full clears.

How do you invalidate caches with Laravel observers?

Hook into created/updated events, then Cache::tags([...])->flush() for the affected tenant.

Does Redis Cache Tags work without Redis?

Nope—requires Redis driver for tag support; others fall back to basics.

Will Redis Cache Tags replace my database?

Nah, they protect it—offload reads, keep writes live for instant invalidation.
