Overview

GeminiDB Cassandra supports cross-region dual-active DR and bidirectional synchronization between two instances at different sites. Once an instance becomes faulty, the other instance takes over read/write traffic to ensure service continuity.

Cross-region dual-active DR allows you to deploy two GeminiDB Cassandra instances in different data centers. Both of the two instances can handle service requests. If a data center becomes faulty, services in the faulty data center can be switched to the other data center to recover services without any interruption.
