Release 3.8

Hardik Chheda Updated by Hardik Chheda

Released in April 2022

We are thrilled to announce our newest release, 3.8. In this release, we've introduced Live Insights, Support for iPad webapp and many more features across the board. Read more below!

Live Insights

Live Insights are available for now Trend Insights, Cohort Insights, and Anomalies. Live insights automatically analyze millions of data combinations without extracting/moving the data from its source. Live Insights are only available on Live connections.

Identify trend drivers: You can diagnose why important metrics and key performance indicators are changing.

Compare cohorts: You can identify the underlying key differences between different groups and cross-sections of data by Cohort Analysis.

Anomaly Detection: Anomaly detection is a process to identify anomalies in time-series data sets that differ from the norm. You can proactively uncover unexpected shifts by having the system continuously monitor data to highlight anomalies and the underlying reasons at a granular level

Display Names in Search Guide

Search Guide now uses the display names instead of original column names.


Support for iPad

Tellius has introduced touch-enabled menu-based interactions for devices such as iPad and other tablets. The changes will be most visible in Vizpads and Search modules. Note: This is available via webapp instead of the native mobile application.

Improvements to Conditional Formatting

Instead of using theme colors, you can specify the hex code (#ffffff) of the color that you want to use for the background and text in the chart.

X/Y axis Target Lines

You can add X and Y target lines for the measure columns in the Scatter chart.

The Scatter Chart with X and Y target lines is shown below:

Unique name for Vizpads

When you create a new Vizpad, a default name Untitled <number> is assigned to it. You cannot save the Vizpad with this default name. You must assign another appropriate name to the Vizpad. The Save button is enabled only when you give another appropriate name to the Vizpad.

Improvements to Vizpad Performance

Major improvements were made to Vizpad performance, including lazy loading of charts as well as grouping many other interactions calls.


Download Business View, Dataset, and Insights for Live BV

You can download various assets, such as Dataset, Business Views, and Insights for Business Views with Live connectivity. Note: Make sure that In-memory operations are enabled on the Settings page since export is an in-memory operation.


Change Start Day of the Week

Chart results for date resolution queries will be based on the time configuration that the admin set up for the environment.

This date will be used to mark the start of a week for time-based calculations.

Customize Help

Administrators can customize the Help experience by providing links to custom assets such as internal documentation and videos. These links to custom assets will replace the out-of-the-box videos and help links that currently assist the users in understanding the product.

Assign User Objects

Users can re-assign their content to a different user. This ownership transfer of the content helps when the user is being removed from the system. When the administrator deletes any user from the system, other users can still access the content or objects from the system. Before transferring ownership, users can preview all content owned by them.

Enable In-memory operations on Live sources

The configuration has been added to enable in-memory operations such as Insights and ML on live Business Views.

Minimum Effective User role for Sharing

This is the effective user role considering the various users' membership in multiple groups/roles. This role is helpful in scenarios where content is shared amongst users, and it helps with the determination of security permissions for various objects. Any user with an effective role below the level of this effective role will be unable to share content.

Users with the View role are restricted from creating Alerts

A user with the View role permission is restricted from creating Alerts.

Update Time-to-Live for Caches

Time To Live (TTL) is the time that Tellius stores an object in a caching system before deleting or refreshing the cache.


Improvements to Insights Algorithms

In the case of ratio or average, absolute change can be on the higher side, but the impact of that on the overall change between the two time periods or cohorts can be very small due to low population. Our prior algorithms were highlighting potential top contributors only based on the absolute difference.

With 3.9, we've updated our Insights algorithm. Impact scores for potential top contributors that represent a very small amount or a very large amount of the data are considered as not interesting and hence suppressed. This modification includes an exponential decay factor below a certain low population threshold and above a certain high population threshold. The exponential decay has a similar effect to simply filtering out candidate top contributors outside of these limits but allows for smoother suppression around the limits.

For example, Change in average interest rate between Q1 and Q2, the top contributor based on the absolute change might be "state = XYZ", but the number of loans associated with that state might be 0.01% of the overall data. Such low population contributors will be filtered out with the updated algorithm.

Fixed Issues

Version Updates
  • Log4j version (existing version number) is updated to the 2.7.1 version to remediate vulnerabilities in the older version of Log4j.
  • Delta Lake JDBC driver updated from (existing) to 2.6.22 to address Log4j issues.
  • Spark updated from 2.4.5 to 3.0.3
  • Python Upgrade to 3.8.15
Prediction is retained when adding/updating calculated columns

If a Model prediction is applied to the Business View, it adds prediction columns to the BusinessView, which can be used for visualization or further analysis. These columns were removed when adding or updating calculated columns to such a business view. This issue has been resolved.

SSO users added to the Usage Data Model

The new users created using SSO were not added to the Users table in the Usage Data Model. This issue has been fixed, and the users are added to the Users table.
