Features and enhancements for 2024.2

Kyvos 2024.2 release brings the following enhancements and bug fixes.

Kyvos Reporting Service

With this release, Kyvos has integrated with Intellicus, allowing users to use the Kyvos Reporting Service offering. Kyvos Reporting Service is a comprehensive Business Intelligence (BI) suite that meets all the required BI requirements, such as importing data from various sources and generating reports quickly. This offering enables users to connect to Kyvos semantic models easily, simplifying the process of data analysis and report generation.

By integrating Kyvos with Intellicus for reporting service, users can benefit from a wide range of analytical features, including customizable options, predictive analytics, and real-time and mobile analytics, all of which can help facilitate decision-making.

NOTE: This offering can be deployed via Kyvos Manager on both on-premises and cloud environments.

Kyvos Modern Architecture with No-Spark Ingestion (Beta)

Kyvos implements Hadoop clusters for semantic model processing and building aggregates with Spark jobs. Each cloud provider offers its own Hadoop implementation (e.g., AWS, Azure, and GCP), leading to several challenges:

1. Complexity: Managing different vendor implementations is difficult.

2. Cost: Semantic model processing is expensive, and costs are borne by the cloud vendor.

3. Time: Analysis with Kyvos takes longer due to dependency on Hadoop cluster resources.

To address these issues, Kyvos has now transitioned from Hadoop clusters to native warehouse technologies for semantic model processing.

The Kyvos Modern Architecture supports the following features with no Spark:

• Deploy Kyvos on all clouds (AWS, Azure, and GCP) without Spark: With this release, Kyvos has added support for no-Spark model processing to deploy Kyvos on all cloud environments through Query Engine or Kubernetes.
  NOTE:

  • For Azure and GCP, users can deploy Kyvos through Kubernetes and Query Engine.

  • For AWS, users can deploy Kyvos through Query Engine.

• Support for no Spark and no Hadoop: The Kyvos 2024.2 release has supported no Spark and no Hadoop for on-premises Kyvos deployments.

• Support of MDX on ROLAP semantic models: With this release, Kyvos has added support for browsing the ROLAP semantic models using MDX and SQL.

• Azure SQL database connection without Spark: With this release, Kyvos has added support for creating an Azure SQL database connection to process semantic models using no Spark model processing.

• LOD queries on a single fact: With this release, Kyvos has added support for optimizing the level of detail (LOD) queries when they are querying on a single fact.

Query memory usage optimization

The Kyvos 2024.2 release has enhanced heap memory utilization for browsing semantic models processed using no Spark model processing.

Kyvos SaaS Portal on AWS for Cluster, User, and Subscription Management

With this release, Kyvos offers a Software-as-a-Service (SaaS) platform on Amazon Web Services (AWS). This new offering allows users to seamlessly orchestrate their clusters, customize subscription plans according to their needs, and efficiently manage user tasks in one place, saving time and effort. The application, designed with role-based access, allows for configuring user roles and permissions, managing subscription plans, and monitoring cluster performance and usage. Its user-friendly web interface provides easy access, with features customized to your specific roles and permissions.
