Hi everyone, I have an Excel file connected to Databricks via ODBC. The SQL statements are very simple, basically just SELECT * from individual tables. The tables are quite large, with the biggest o...

Hi
Won't be able to help at all with this & you did not mention where you Databricks sits (Azure/AWS...) so not sure the following pointers are relevant…
- Performance issues with multiple slicers in "Analyze in Excel"
- Databricks ODBC Driver download
Looks like version >/= 2.6.15 is the min. in your context - Create an ODBC DSN-less connection string for the Databricks ODBC Driver
- Driver capability settings for the Databricks ODBC Driver
- Databricks ODBC Driver (MSFT)
- Create an ODBC DSN for the Databricks ODBC Driver (MSFT)
- Databricks Community
Depending on the ODBC Driver capabilities some little optimizations might be possible… - Excel 2508 PivotTable Data Model Slowdown: Power Pivot Regression, Slicer Lag... Workarounds
TRUE/FALSE? No idea
basically just SELECT * from individual tables. The tables are quite large, with the biggest one having around 5 million rows
In such a context wonder if SELECT * is the best option
adding slicers slows the report down significantly. I’ve tried suggesting using PivotTable filters instead
I would test perf. using the Pivot Charts filters (instead of the slicers). If by any chance perf. are better, would this be acceptable workaround would be the next question to the user
Forgive me if this is all irrelevant
