CNODES and VIPs

CNODES and VIPs#

CNodes#

Aim for a ratio of 4:1 CNode to DNodes for Database workloads. That is for every DNode, there should be 4 CNodes.

Virtual IP’s#

Use either 2 or 4 VIPs per CNode.

  • 2 VIPs/CNode (Minimum):

    • Handles normal data traffic.

    • Provides basic redundancy.

  • 4 VIPs/CNode (Recommended):

    • Optimizes data rebalancing during scaling.

    • Increases rebalancing speed and concurrency.

    • Reduces performance impact during rebalance.

    • Increases network throughput.

  • Why Rebalancing?

    • Maintains balanced workload after adding/removing CNodes.

    • Ensures optimal performance.

  • Best Practice:

    • Use 4 VIPs/CNode for production to ensure smooth scaling.
