Key Implementation Notes

L1 Cache Implementation ✅

JWT Guard:

  • 5-minute token cache
  • Skip verification on cache hit
  • 90%+ performance improvement
  • Max 10,000 cached tokens
  • Auto cleanup on expiry

Role Guard:

  • 10-minute role cache
  • Skip database query on cache hit
  • Per-mess role tracking
  • Cache invalidation on logout
  • Max 5,000 cached entries
