Handling Cache Failures

Key Concepts

• Cache Failure Impact

  • Sudden cache failures can lead to increased load on backend systems.
  • This may result in a cascading failure, causing backend systems to collapse.

• Recovery Challenges

  • Recovery often relies on the cache.
  • If the backend is inaccessible, data cannot be repopulated to the cache.

Considerations for Cache Implementation

• Thorough Planning
  • Consider potential problems when introducing caching to applications.
  • Evaluate scenarios where caching may not be beneficial or necessary.

Conclusion

• Properly plan and assess the need and strategy for caching to prevent and mitigate failures.
