Error when trying to build the Semantic Model for Power BI

🐛 Problem

After adding historical data the semantic model fails to build with the following error:

Data source error: Expression.Error: Query execution lacks memory resources to complete (80DA0007): Partial query failure: Low memory condition (E_LOW_MEMORY_CONDITION). (message: 'bad allocation (E_LOW_MEMORY_CONDITION)', details: '').

👣 Repro steps

TODO: Add repro steps below:

1. Deploy FinOps Hubs in Fabric
2. Export historical data for ~ 1 year (13GB worth of data)
3. Build the Semantic Model
4. See error

🤔 Expected

Semantic model should builds successfully after ingesting the historical data

No files or tests are named. Start by reproducing the failure using FinOps Hubs in Fabric with about one year of historical data, then investigate the Semantic Model build path and the reported low-memory Kusto error. Done means the Semantic Model builds successfully after ingesting the historical data.
