I wanted to know how we can achieve automatic failover to second region with Astra DB multi region set up in case primary region cluster is not available? I know we can configure this in DSE, looking at similar configuration or approach in Astra DB.
@praveenkg it can be achieved using the same fashion how you're achieving it today with DataStax Enterprise (DSE) cluster.
I am assuming your app is deployed similar to the below with DC1 and DC2 being Astra DB regions.
Other useful resources are available here,
- Connecting to Astra DB
- Designing Fault-Tolerant Applications with DataStax and Apache Cassandra™ Whitepaper demonstrating failover
- DC Failover Demo with code (you just have to adjust that for Astra DB with Secure Connect Bundle)
- Another option is to leverage Astra SDK. Here again, the recommended approach is to leverage the failover at the infra layer above the application (or) forcefully do it at the client side.
I hope that helps!
