Graph Database (GDB) offers two editions: High-availability and Single Node. The High-availability Edition uses a classic architecture with a primary and a secondary node, both of which are independent Graph Database nodes. This edition decouples compute from storage, providing higher availability than the Single Node Edition.

Benefits

  • Availability

    This edition uses a classic high-availability architecture. Data is synchronized between the primary and secondary nodes through replication, which is semi-synchronous by default. If the primary database fails, the system detects the failure and switches to the secondary database to ensure availability. A failure on the secondary database does not affect your services because the system detects the failure and promptly triggers self-healing.

  • Reliability
    • Because compute is decoupled from storage, a failure on a compute node does not cause data loss.
    • This edition is built on the large-scale Alibaba Cloud Apsara distributed storage system, which ensures the reliability of multiple data replicas.

Scenario

Enterprise-grade graph databases for production environments.
