Note

  • From Kyvos 2024.11 onwards, you can process a flexible semantic model allows the summary function of a dimension or measure to be modified at any time during SQL queries.
    To do this,

  • When you process a semantic model with no Spark, cuboids are stored at persistent storage. However, a copy of these cuboids is kept at the local storage (local disk).

  • Shared Query Engine: In this mode, the query engine not only performs queries but also handles semantic model processing. This dual role is named SHARED because the same process undertakes both activities.

Note

From Kyvos 2024.9.1 onwards, if If you use Query Engines as a compute server:

  • For Load Based Scaling: Query Engines will be automatically started when the semantic model is processed.

  • For Schedule based scaling: Query Engines will start automatically when the semantic model is processed. However, if you have enabled schedule-based scaling, the Query Engines will not start automatically. In such cases, Kyvos recommends switching to load-based scaling.

...

You can change from an external compute cluster to Kyvos Native for processing semantic models through Kyvos Manager on the Compute Cluster page.

From Kyvos 2024.10 onwards, you can

  • Process semantic model with no-Spark using the Shared Query Engine and dedicated Kubernetes cluster on AWS Managed Services.

  • Resume failed or canceled semantic model process.

  • Run test data semantic model process job.

...

  • To execute the sanity suite for no-spark and Kubernetes (K8S) supported deployments, refer to the Prerequisites for no-spark deployments section.

  • Modify the value of the following semantic model advanced properties on Kyvos Web Portal:

  • You can also set subtype to select no-Spark model processing for semantic model via property.
    To do this, navigate to the Kyvos Properties page and update the KYVOS_PROCESS_COMPUTE_SUBTYPE property and restart Kyvos services.

  • For no-Spark deployments with enhanced security, when creating a Kyvos warehouse connection of a Databricks managed workspace, ensure that the firewall settings on the storage account are disabled.
