account level & request level options "Consistency can only be relaxed at the SDK instance or request level. To move from weaker to stronger consistency, update the default consistency for the Azure Cosmos DB account." https://learn.microsoft.com/en-us/azure/cosmos-db/nosql/how-to-manage-consistency?tabs=portal%2Cdotnetv2%2Capi-async

to clarify order in strength of consistency models is: Strong (side note. not applicable to Multi Region Write architecture!), Bounded Staleness, Session, Consistent Prefix Eventual. Bounded Staleness is stronger than session so cant be overridden in the SDK level. Consistent Prefix is weaker than session so it can be overridden in the SDK level.

Bounded staleness > account level Consistent prefix > request level "The default consistency level configured on your account applies to all Azure Cosmos DB databases and containers under that account." https://learn.microsoft.com/en-us/azure/cosmos-db/consistency-levels#configure-the-default-consistency-level **No option to set consistency level at database level. requirements for multiple default consistency levels = multiple accounts

Consistency can only be relaxed at the SDK instance or request level. To move from weaker to stronger consistency, update the default consistency for the Azure Cosmos DB account. For Bounded staleness --> Account For Consistent prefix --> Request Level https://learn.microsoft.com/en-us/azure/cosmos-db/nosql/how-to-manage-consistency?tabs=portal%2Cdotnetv2%2Capi-async#override-the-default-consistency-level
