Learn Distributed Datasource Groups (DDG) in Tungsten Cluster, a single unified cluster split into logical, site-based groups with a single global Primary and local-first failover to minimize cross-site latency and improve resilience.
This session explains DDG architecture, when it avoids cross-site failover, and how Connectors route reads locally while writes go to the global Primary, keeping operations consistent across sites without multi-cluster management overhead.
You’ll review installation and configuration, including per-node datasource-group-id assignments, grouping nodes with the same ID, and a sample tungsten.ini showing defaults, REST API security, and members/connectors for a 5-node DDG deployment.
