Offline-First Apps with Angular, Ionic, PouchDB, and CouchDB - CAP-Theorem, Eventual Consistency, Update Is Better Than

What is the primary reason for adding more nodes to the initial CouchDB setup?

• To simplify the system architecture

• To reduce the cost of operations

• To enhance fault tolerance and availability

• To increase the speed of data processing

According to the CAP theorem, which two properties does CouchDB prioritize?

• Consistency and Availability

• Scalability and Security

• Availability and Partition Tolerance

• Consistency and Partition Tolerance

What is the term used to describe the state when all nodes eventually reach the same data state?

• Immediate Consistency

• Eventual Consistency

• Strong Consistency

• Weak Consistency

What challenge arises when multiple nodes handle requests in a distributed system?

• Difficulty in ensuring the latest data state

• Higher costs of data storage

• Complexity in user authentication

• Increased latency in data retrieval

How can the system ensure it displays the most recent changes in a distributed setup?

• By reducing the number of user requests

• By increasing the number of nodes

• By implementing change notifications and updates

• By using a single master node
