According to the CAP Theorem, which two properties must a distributed system choose between when a network partition occurs?

Partition Tolerance and Latency

Why is 'Partition Tolerance' generally considered a mandatory requirement for any real-world distributed system?

Network failures and communication breakdowns are inevitable in distributed environments.

To ensure all data is eventually consistent.

To allow for horizontal scaling across multiple data centers.

To maximize data retrieval speed under normal operating conditions.

Availability and Partition Tolerance (AP)

Consistency and Partition Tolerance (CP)

Consistency and Availability (CA)

Durability and Partition Tolerance (DP)

Prioritizing Consistency over Availability

Prioritizing Availability over Consistency

Prioritizing Partition Tolerance over Consistency

Prioritizing Latency over Consistency

During a network partition, some nodes may become unavailable to ensure data integrity across the system.

During a network partition, all nodes remain responsive, but data might be inconsistent.

The system never experiences network partitions.

All data is replicated across all nodes, guaranteeing high availability and eventual consistency.

Network partitions are an inevitable reality in distributed systems, making Partition Tolerance a necessary property.

It would be too expensive to implement at scale.

It inherently means the system is not truly distributed, operating effectively as a single node.

Such a system would have extremely high latency under normal operating conditions.

CP: prioritizes consistency, meaning some parts of the system might become unavailable during a partition to ensure accurate data.

AP: prioritizes availability, meaning some customers might see stale data but can always make purchases.

CA: prioritizes consistency and availability, implying no partitions would ever occur, which is unrealistic.

CP: prioritizes partition tolerance, meaning data will eventually be consistent but immediate availability is always guaranteed.

AP (Availability over Consistency)

CP (Consistency over Availability)

CA (Consistency and Availability)

AC (Atomicity over Consistency)
