Remarks

Azure Cosmos DB offers 5 different consistency levels. Strong, Bounded Staleness, Session, Consistent Prefix and Eventual - in order of strongest to weakest consistency. ConnectionPolicy

Azure Cosmos query/DB feed operations may be retrieved from many partitions, each accessed across many round trips. The consistency level is honored only within a partition and round trip.

While this is set at a database account level, Azure Cosmos DB allows a developer to override the default consistency level for each individual request.
