Application service configuration of a timeframe for performing dataloss failover (failover that does not attempt full data replication to the secondary data store) from a primary data store to the secondary data store. A data-tier service, such as perhaps a database as a service (or DBaaS), could receive that configuration from the application service and automatically perform the any dataloss failover as configured by the application service. This relieves the application service from having to manage the failover workflow while still allowing the application service to appropriately balancethe timing of dataloss failover, which will depend on a very application-specific optimal balance between the negative effects of operational latency versus dataloss. 一种用于执行从主数据存储库到辅助数据存储库的数据丢失故障转移(不尝试到辅助数据存储库的完全数据复制的故障转移)的时间帧的应用服务配置。数据层服务(诸如可能的数据库即服务(或DBaaS))可以从应用服务接收该配置，并且自动执行如由应用服务配置的任何数据丢失故障转移。这使应用服务不必管理故障转移工作流，同时仍然允许应用服务适当地平衡数据丢失故障转移的定时，这将取决于操作延迟与数据丢失的负面影响之间的非常特定于应用的最优平衡。
