Hi Pigmenteers!
When reading Top Tips for modeling in Pigment - Part 2: Performance Optimisation, there’s an idea as highlighted in the screenshot below: to avoid doing too much within one metric, there’s “a good guideline is that, if you have to copy and paste part of a formula more than once, it may be worth its own metric” - I don’t quite get it, can you help explain this idea to me?
Hi Thu Mai,
copy paste here means that the same “formula” exists in two metrics as part of a larger one.
We advise for that in order to avoid Pigment recalculating the same thing in several metrics & being able to parallelize calculations.
example of too much recalculations:
Salary = Annual Salary /12 * prorata(month,Employee.Start, Employee.End)
Tax = Annaul Salary / 12 * TaxRateaby:Employee.Country] * prorata(month,Employee.Start, Employee.End)
You should rather do that:
FTE = prorata(month,Employee.Start, Employee.End)
Salary = Annual Salary /12 * FTE
Tax = Salary *TaxRate*by:Employee.Country]
