Which consistency option in Cosmos DB is characterized by the lowest latency and least consistency?

The option that represents the consistency level characterized by the lowest latency and least strict consistency in Azure Cosmos DB is Eventual Consistency. This model guarantees that if no new updates are made to a given piece of data, eventually all accesses to that data will return the last updated value. It allows for the highest throughput and minimal latency since it does not require immediate synchronization across replicas.

With Eventual Consistency, there may be a time lag before all updates are visible to all clients, which means applications can read stale or outdated data temporarily, enhancing performance and reducing wait times. This makes it particularly suitable for scenarios where absolute consistency is not critical, such as social media feeds or caching systems.
