Hi,
I have one Attribute view with a master data/hierarchy table with 35M records and that has been joined to 3 different fact tables in the Logical Join of 3 Analytic Views each with some calculated columns here. The Joins I have maintained is the referential join throughout. I have also created a Graphical Calc. View which is the Union of this 3 Analytic Views.
As I am executing the query on this Calc. View or performing the Data Preview, its taking 40 seconds approx. to show the data.
I am trying with only few attributes and measures, the same query takes 2 seconds, but as I start adding more columns to the query, the elapsed time exponentially raises to 40 seconds.
I tried partitioning the table, changing the join type to LOJ, maintaining the cardinality. Regarding the filter of data at the base tables, I don't want to use any Input Parameter or want to apply Variable filter anywhere across the Model.
Please suggest where can I check in my model or the tables in schema to achieve a significant level of performance in the query of this Calc. View.
Thanks in advance...
