Optimize BI dashboard performance and reduce costs with Databricks managed tables, liquid clustering, Metric Views, and aggregate-aware materialization.
Your BI dashboards are slow, and tuning them is costing too much time and money.
It's a familiar pattern. A dashboard query takes 30 seconds, so someone builds an aggregate table to speed it up. That table needs a refresh pipeline. The pipeline needs monitoring. Then a second BI tool needs the same data in a slightly different shape, so someone builds another aggregate table using a separate pipeline. Before long, you're managing a sprawl of aggregates, extracts, and tool-specific semantic layers — each with its own staleness window, its own governance gaps, and its own line item on the compute bill.
