Insights
This release brings backend improvements that enhance performance, efficiency, and the accuracy of insights across the platform. It brings more cost-saving recommendations focusing on workload rightsizing and optimization. The following insights are included in this release:
Rightsizing for Streaming Workloads:
For fixed-sized clusters, recommendations are provided to optimize cost and performance.
For autoscaling clusters, to ensure efficient resource allocation during scaling events.
Rightsizing Recommendations for Autoscaling Scenarios:
For long-running tasks within a job run, optimizing resource usage throughout task execution.
For parallel executions of tasks within a job, enhancing efficiency for simultaneous processes.
For contention on driver scenarios, reducing resource competition on the driver node to improve performance.
Conservative Savings Model: A new savings model provides cost-saving insights across all categories, even when direct cost bindings are unavailable.
Instance type whitelisting has been implemented to provide enhanced control over the types of instances used for receiving insights, ensuring that only approved instance types are utilized.
Home page
The Top-X page now includes a "Most Wasted Cost" widget, highlighting the costs associated with failed and killed jobs, allowing users to quickly identify and address inefficiencies.
Customer ValueGen app
This release introduces a new Customer ValueGen app with comprehensive workload analysis, ROI computation, and productivity insights for Databricks environments. The app enables users to analyze historical data, benchmark costs, and identify optimization opportunities to drive enhanced cost efficiency and operational improvements. It includes features for evaluating savings potential, monitoring the cost and savings funnel, and running various diagnostics on the status of insights. Additionally, users can conduct productivity boost analysis and mark applications as interesting to focus on key areas for optimization.
Databricks Partner Connect
Unravel Data is now integrated into the Databricks Partner Connect page, allowing end users to directly create trial accounts for greater flexibility.
Data Pipelines and Improved Cost Insights
Enhancements to secondary data pipelines have been made to ensure better performance, improved monitoring, and greater consistency across the platform. Additionally, backend changes on the Cost Explorer page now deliver more accurate insights, providing you with more precise real-time costs in trends, drill-downs, and budget tabs.
UI Updates
This release includes several UI improvements to enhance clarity and readability across the platform. These updates include refined color schemes and label adjustments to ensure better visual contrast and a more intuitive user experience. In addition, sorting and search issues as well as consistency and accuracy problems are addressed, ensuring a more seamless and accurate experience across the platform.
Security, Infrastructure and Compliance
Critical security vulnerabilities related to Public/Internal Services have been addressed, and the handling of encrypted sensitive values has been improved.
Activities related to CentOS 7’s end-of-life in June have been completed.
Configuration management capabilities for non-Kubernetes environments have been enhanced, and the installation and build processes have been streamlined for faster deployments.

Azure bill integration
Actual bill data is not live; once configured, it will be available from Azure once every day. The cost for a few clusters may be updated after a couple of days in the bill.
One record per cluster per day is maintained, even if the cluster is restarted multiple times within a day or cluster sessions span across multiple days.
If there are issues with Azure billing, the cost data will not be updated on Unravel.
Tags on cost pages come from actual cost data, while tags on the compute page come from Spark configuration. There is a possibility that the tags on these pages don’t match. This issue will be fixed in the upcoming release.
Billing
Some discrepancies may occur in cost calculations due to differences between the user time zone displayed on the Compute page and the UTC-based aggregation on the Billing page. (DT-2350).
In certain scenarios, the budget status may inaccurately display as Ok even when the budget has been exceeded. This discrepancy occurs when Azure billing is enabled and is a known limitation. Notifications for budget can be delayed by two or three days due to the minimum 24-hour delay in receiving bills. (DT-3091)
Compute
Jobs by status graphs in the Trends tab display spark application details and not the job details. Our development is actively looking into this design limitation and efforts are underway to address this in future updates to enhance the product's capabilities. (DT-2008)
Data is inconsistent between Compute page and Cost page in some cases when Azure bill is enabled. This is a known limitation because of Azure bill data not being live. Our team is actively looking into this limitation and efforts are underway to address this issue in the future updates. (DT-3078)
Data
If tables are created with the same name, accessed, deleted, and re-created, and if those tables are re-accessed, then their query and app count do not match. (DATAPAGE-502)
Home
Home page does not display alerts on the UI when there is missing ROI data for a single day. (DT-2509)
Hovering on Total Cost Trend on the Summary tab of the Home page may display inaccurate date information. (DT-2408)
Insights Preview
In some cases, there is a discrepancy in the runs displayed in the Job Runs page for the selected job. When you click on View runs, only runs with
dbx_cluster kindhaving a Spark app id are listed. The discrepancy is due to data inconsistency between entries ofdbx_cluster kindanddb kindand this is an expected behavior. (DT-3042)Workflows
The current implementation has a limitation where the wrong run count is displayed for the job ID when sorting by run count in the Workflows > Jobs section. This discrepancy is currently under investigation by our development team, and active efforts are being taken to resolve this issue. (UIX-6526)
Our development team is actively investigating the following Known issues and are working towards resolving them. It is important to note that while these issues exist, there is no immediate critical impact on using the product, and users can continue to utilize its functionality with confidence.
