What is ZooKeeper’s CAP theory?

In ZooKeeper, the CAP theory states that in a distributed system, consistency, availability, and partition tolerance cannot be guaranteed simultaneously, and only two out of the three can be chosen to be ensured. For ZooKeeper, the choice based on the CAP theory is to ensure consistency and partition tolerance, meaning that when a network partition occurs, the system will maintain consistency but may sacrifice some availability. Therefore, ZooKeeper is a distributed system that emphasizes consistency and partition tolerance.
