Please define an example lambda function, in order to see whether there is an sql equivalent.
Imo >90% of the data issues i have seen, can be solved with sql queries. I have seen some in the finance sector which would require super complex udfs, but other than these, sql is the first choise to solve a data issue.
- pandasusr 5y agoI do work in finance sector and need complex functions :) And it’s interesting that pandas was invented at a hedge fund, AQR. I agree that SQL may be better for vanilla BI.
