About

Partition tolerance means that the system continues to work even if nodes can no longer communicate.

In the context of the cap theorem, partition tolerance means that the system continue to work even if a network partition causes communication errors between subsystems.

This means that the data is replicated.

Example of network problems

• when switch between the two subnets fails, the network is partitioned.
• an arbitrary number of messages are being dropped (or delayed) by the network between nodes.
