Issue Status: RESOLVED

Issue Description: Users may see incorrect results with certain queries when using result set caching in Microsoft Fabric.

More info: This issue specifically impacted results with the queries in Fabric Data Warehouse and SQL Analytics Endpoint when the result set caching feature was active. The results may have included incorrect cached items or excluded relevant cached items.

We disabled the result set caching feature as of February 16, 2026, to prevent any confusion or misinterpretation of results. For any reports or downstream apps using cached results on or prior to February 16, 2026, from the Data Warehouse or SQL Analytics Endpoints, users will need to manually refresh to obtain relevant results. This will ensure that these other apps don’t continue to work with potentially incorrect results.

Final Update: 06/03/2026 8:16:00 AM – Microsoft has confirmed that disabling the result set caching feature has prevented the problem from spreading further. While they will expect that will have a fix deployed at the end of April 2026, users will need to manually refresh the affected reports and downstream apps as outlined in the More info section to remediate the issue until that time. Please reach out to a support representative for additional help with manually refreshing the reports and apps or if the manual refresh isn’t successful in providing the appropriate results.

Scope of impact: This issue may potentially impact any user utilising result set caching in Microsoft Fabric.

Root cause: A code issue with the result set caching feature in Microsoft Fabric is causing incorrect results with certain queries in Fabric Data Warehouse and Lakehouse SQL Analytics Endpoint.

Next steps: Microsoft are continuing to develop a long-term fix to fully resolve the result set caching feature issue and restore query result accuracy for both Fabric Data Warehouse and SQL Analytics Endpoint. We anticipate that this long-term fix development and safe deployment process will complete by Thursday, April 30, 2026
