How can I ensure data consistency in distributed systems?

To ensure data consistency in distributed systems, you can implement techniques like consensus algorithms, data replication, and distributed transactions.

What are consensus algorithms, and how do they help?

Consensus algorithms, like Paxos or Raft, help multiple nodes agree on a single value, ensuring consistency across the system.

Are there any trade-offs with using these algorithms?

Yes, using consensus algorithms can introduce latency and complexity, as they require communication between nodes to reach agreement.

What about eventual consistency? Is it a good approach?

Eventual consistency can be a good approach for systems that prioritize availability over immediate consistency, but it may lead to temporary discrepancies.
