Add way to specify custom prefix for partitioned file outputs #19261
Description
Is your feature request related to a problem or challenge?
Currently there is no way to control file name for generated files when you write partitioned outputs
Describe the solution you'd like
I would like to have option to allow user to specify prefix which would allow user to have predictable part of file name instead of just randomised or part-X
Describe alternatives you've considered
A more complex solution would be to introduce function callback that would be called to generate such prefix which would enable user to customise behaviour of prefix generation or replace randomized generation with his own implementation
