Which of the following scenarios would LEAST likely benefit from Eventual Consistency?

An e-commerce product catalog with item availability

Consider a distributed database. If a write operation is acknowledged only after it has been successfully written to a majority of replicas, what consistency model is being enforced?

Strong Consistency (e.g., Quorum writes)

All replicas are updated synchronously.

Reads always return the most recently committed write.

System can remain available during network partitions.

It is generally easier to implement and scales better than eventual consistency.

Ensuring data availability during network partitions.

Achieving low latency for write operations.

Handling a high volume of read requests.

Managing the complexity of garbage collection.

They might read stale data for a period.

Writes might be rejected due to conflicts.

All operations are guaranteed to be atomic.

The system will always provide the latest data across all replicas.

Higher complexity in implementation and maintenance

Guaranteed immediate visibility of writes across all nodes

Increased availability during network partitions

Lower latency for write operations

A system for managing bank account balances and transactions

A distributed cache for website static assets

A recommendation engine suggesting movies

A real-time multiplayer game state

Immediate rollback of conflicting writes

It is a stronger form of consistency than Sequential Consistency.

It guarantees that reads will always return the value of the most recent successful write across the entire system.

It allows for the system to remain available during network partitions.

It is the same as Eventual Consistency.

Increased complexity in conflict resolution.

Possibility of reading stale data.

Higher latency for write operations.

Reduced system availability during network partitions.
