From Kyvos 2023.3 onwards, you can now manage Query Engines nodes and disks that need to be attached to the Query Engine node directly from the Node and Services > Overview page. This page displays the number of nodes and disk details added to each Query Engine node and the number of configured services such as BI Server, Web Portal, and Query Engines on the cluster nodes. You can also view the specific details of these services.

This allows for efficient modification of the Query Engine node count and disk allocation without the need to create EC2 instances for cloud deployments. You can effortlessly adjust the capacity to handle peak demand times. Additionally, you have the ability to manage Query Engine nodes and disks based on query traffic and usage. These adjustments can be made swiftly and efficiently, resulting in an improved performance for the Kyvos cluster.
