From Kyvos 2024.2 onwards, load based scaling is implemented based on the CPU and Memory usage of the Query Engine instances. System resources are monitored for all BI Servers and Query Engines every 30 seconds, and Query Engines’ scaling will be performed based on this data.

Note

If you select the Query Engine as a compute server, ensure the following:

  • Start the Query Engine when the semantic model process is started.

  • Skip the scaling and shutdown of the Query Engine when the semantic model is processing.

The cluster will be scaled up step-by-step. For instance, it will scale from Low to Moderate and then from Moderate to High. Similarly, when scaling down the cluster, it will scale from High to Moderate and then from Moderate to Low.
