Unravel Billing page update
Unravel's billing page has been updated to introduce the new Pro Plan with Pay-In-Advance (PIA). This latest pricing model offers you the flexibility to purchase credits upfront with discounts. With PIA, you can monitor your purchased credits, opening and closing credit balances, total credit usage, and adjusted credits throughout the month. The transition to PIA ensures that you have access to more accurate billing, aligned with your individual usage patterns and requirements. For more details, see Unravel Billing for Databricks platform.

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.
