Yes. Tair (Enterprise Edition) DRAM-based instances support Global Distributed Cache, which reduces access latency for cross-region and long-distance access while supporting geo-disaster recovery.
How it works
A Global Distributed Cache instance consists of up to three child instances deployed across regions. Data is automatically synchronized among child instances in real time, so each region serves reads locally rather than routing requests across long distances.
Key capabilities
Reduced access latency Each child instance handles local read traffic, eliminating the round-trip cost of cross-region access. This improves application responsiveness for globally distributed users.
Real-time data synchronization Data is automatically synchronized among all child instances in real time, keeping all child instances in sync.
Geo-disaster recovery With data replicated across multiple regions, the architecture supports geo-disaster recovery. If one region becomes unavailable, traffic can be redirected to another child instance.
Prerequisites
Global Distributed Cache is available on Tair (Enterprise Edition) DRAM-based instances at no additional charge. Other instance types do not support this feature.
