Is your feature request related to a problem? Please describe.
I am struggling with including the multi-column great-expectations for my current projects. For instance, given a list of columns I want to check if each next column values are higher than the values in previous one. Is the any way it can be implemented through custom expectations? In the documentation only the templates for one-column expectations can be found.
Describe the solution you'd like
Ideally, there could be the template for the expectations which take the list of columns as inputs and some values as arguments which can be overridden depending on the functionality required.
Describe alternatives you've considered
I considered to implement a function which would take the list of columns and produce one column with 0 where the values are rising and 1 otherwise and then use the
expect_column_values_to_not_be_in_set
. However, this solution seems bulky and requires new function to be added to the project.Beta Was this translation helpful? Give feedback.
