Question

I have a somewhat convoluted question apologies I am currently writing a job that does a series of transformation on a pandas dataframe At the end of the pipeline I d like to persist the dataframe to a mysql database I currently have this implemented as just a standalone `op` but based on the documentation I ve read so far I have a feeling that there s a way to do this using defined assets and io managers Is there a concrete example of this somewhere Thanks and sorry for the half baked question
