Kyvos Modern Architecture (No-Spark Ingestion) Enhancements

This release comes with the following no-Spark enhancements:

• Support for creating levels of date data type from the ‘Date’ column.

• Support for formatting on levels and attributes with underlying field type as numeric. This is applicable only for Kyvos Viz.

• Support for decimal data type for level and attribute in dimensions.

• Support for filtering calculated members will enable users to select one or more calculated members in the filter list, just like other data members by setting the value of the kyvos.query.calculated.member.filter.enabled property to true. This capability allows users to filter and customize views based on their needs while enhancing Kyvos' complex data analytics. 

• Refined User Interface (UI) for the processing of metadata for attributes. This enhancement improves clarity and usability, enabling users to understand the metadata process easily.

• Support for processing Parent-Child hierarchy.

• Enhancements in the single table semantic model:

  • Support of calculated measure in flexible query

  • Support of distinct count measure in MDX on raw data value

  • Support of calculated members with flexible queries

Kyvos SaaS Enhancements

This release comes with the following Kyvos SaaS enhancements:

• Support for deleting invited users within the account now exists. This applies to Portal users and Admins, but they cannot delete the owner of the account, ensuring that the highest level of control remains secure.

• Support for downloading payment gateway transaction receipts from the ‘Transaction History’ tab.

• Support for dynamic time zone. This feature automatically detects the user's time zone based on their device settings or IP address, ensuring that all time-related data is relevant to their local time. Once the user's time zone is identified, the application converts all time values accordingly. This includes timestamps for cluster creation, audit logs, transactions, and any other time-sensitive information.

Support for Oracle Analytics Cloud (OAC) connection

Kyvos now supports Oracle Analytics Cloud (OAC) connection for querying semantic model.

Support for ROLAP queries on Postgres data source with Spark

Users can now query the semantic model designed over the Postgres source without processing it using the old architecture, i.e., with Spark.

Kyvos Manager Enhancements

This release comes with the following Kyvos Manager enhancement:

• Thread Dump Management: Kyvos now supports generating and downloading thread dumps directly from the Logs Files tab, available on the Monitor page. With this release, users can:
