What are the challenges of transaction control in distributed systems?

The main challenges include ensuring data consistency, handling network failures, and managing concurrency.

How do distributed transactions ensure atomicity?

Distributed transactions use protocols like Two-Phase Commit (2PC) to ensure that all parts of the transaction either commit or roll back.

What is the role of consensus algorithms in transaction control?

Consensus algorithms, like Paxos or Raft, help achieve agreement among distributed nodes, ensuring consistency in transaction processing.

Can you explain the difference between strong and eventual consistency?

Strong consistency guarantees that all reads return the most recent write, while eventual consistency allows for temporary discrepancies.

What tools can help manage transactions in distributed systems?

Tools like Apache Kafka, Google Spanner, and Amazon DynamoDB provide features to manage transactions effectively in distributed environments.
