Challenge Problems

Push your limits with challenges.

Question 1

You are tasked with designing a consensus algorithm for a distributed database system with frequent network failures. How would you incorporate stable leader election, random back-off timers, and quorum sizing into your design?

💡 Hint: Think about how each component can interact within your design for optimal performance.

Question 2

Evaluate a situation where using a large quorum size may lead to system inefficiencies. Propose adjustments that could maintain system reliability while minimizing delays.

💡 Hint: Consider trade-offs between speed and reliability based on system load or activity.
