 The database availability API supports lag-aware availability checks that consider replication lag tolerance. You can reduce the risk of data inconsistencies during disaster recovery by incorporating lag-aware availability checks into your disaster recovery solution and ensuring failover-failback flows only occur when databases are accessible and sufficiently synchronized.

-The lag tolerance threshold is 100 milliseconds by default. Depending on factors such as workload, network conditions, and throughput, you might want to adjust the lag tolerance threshold using one of the following methods:
