Question 1

What does a Lamport Timestamp ensure?

  • It provides synchronized clocks.
  • It ensures causality among events.
  • It records all events in real time.

๐Ÿ’ก Hint: Consider the role of causality in event ordering.

Question 2

True or False: Lamport Timestamps can identify concurrent events.

  • True
  • False

๐Ÿ’ก Hint: Think about what 'concurrent' means in this context.

Challenge Problems

Push your limits with challenges.

Question 1

Create a distributed application using Lamport Timestamps for managing events. Explain how you would handle message passing and state updates without global timestamps.

๐Ÿ’ก Hint: Think about how to maintain order without a central control.

Question 2

Hypothesize a scenario where relying solely on Lamport Timestamps could lead to an inconsistency in a distributed application.

๐Ÿ’ก Hint: What could happen if events are perceived as ordered, but they aren't?
