What is eventual consistency in the context of NoSQL databases?
- Data consistency is guaranteed eventually
- Data consistency is guaranteed immediately
- Data consistency is not a concern
- Data is consistent at all times
Eventual consistency refers to the property of NoSQL databases where updates made to the data will eventually propagate through the system, ensuring consistency across replicas or distributed nodes over time. It acknowledges that there may be temporary inconsistencies during the replication process but guarantees that eventually, all replicas will converge to a consistent state. This approach is common in distributed systems to achieve high availability and partition tolerance while sacrificing immediate consistency.
