 - **Changed**
   - Added a callout to the `config_RunBackfillJob` backfill option clarifying that it isn't supported on Microsoft Customer Agreement (MCA) billing accounts or billing profiles ([#2113](https://github.com/microsoft/finops-toolkit/issues/2113)).
+- **Fixed**
+  - Fixed Data Factory ingestion memory pressure during emptiness filtering.
+    - Replaced `isnotempty(strcat(x_SkuMeterId, x_SkuOfferId))` with separate `isnotempty()` checks in FinOps hub ingestion scripts to avoid temporary string allocation.
