Why do distributed databases like Dynamo and Cassandra utilize vector clocks?

Q: Why do distributed databases like Dynamo and Cassandra utilize vector clocks?

Distributed databases like Dynamo and Cassandra utilize vector clocks to maintain consistency among replicas. This technique helps in resolving conflicts and providing a partial ordering of events. Vector clocks are logical clocks used in distributed systems to capture the causal relationships between different events. They help in synchronizing the system and ensuring that all the operations are executed in the right order. In distributed databases, vector clocks play a crucial role in tracking the state of each node. When data is updated, the vector clock for that data item on the node is updated as well. This way, each node can keep track of the updates made to every other node. When conflicting updates occur, vector clocks help in determining which update happened before the other, allowing the system to resolve the conflict. If the system can't determine the order based on the vector clocks, it will flag the conflict for resolution at the application level.
