How do I implement sequential consistency in distributed systems?

To implement sequential consistency, you need to ensure that all operations appear to be executed in a sequential order. This can be achieved by using a centralized coordinator or timestamps.

What are the challenges in achieving sequential consistency?

Some challenges include handling network partitions, ensuring low latency, and managing the overhead of coordination among distributed nodes.

Can you give an example of a system that uses sequential consistency?

Sure! One example is Google's Spanner, which uses a combination of timestamps and a distributed consensus algorithm to maintain sequential consistency.

Are there alternatives to sequential consistency?

Yes, alternatives include eventual consistency and causal consistency, which may offer better performance in certain scenarios.
