Scenario: Your distributed system relies on message passing between nodes. What challenges might arise in ensuring message delivery and how would you address them?
- Message duplication and out-of-order delivery
- Network latency and packet loss
- Node failure and message reliability
- Scalability and message throughput
In a distributed system relying on message passing, challenges such as network latency, packet loss, and node failures can impact message delivery and reliability. To address these challenges, techniques like message acknowledgment, retry mechanisms, and message queuing systems can be implemented. Using reliable messaging protocols such as TCP/IP or implementing message brokers like RabbitMQ can ensure guaranteed message delivery even in the presence of network failures or node crashes. Additionally, designing fault-tolerant architectures with redundancy and failover mechanisms can enhance the reliability of message delivery in distributed systems.
