I want to create a python function API endpoint that has access to a large pandas data frame in memory. I do not want to read the same data into a dataframe every time a request is made.
Is this possible? If so, how is best to do this?
It would be too slow to do as suggested here:
Thank you for your reply. Yes, it works!
I was having some trouble with how to actually build it outside the api_py_function. What worked best for me was to first write it to csv in a managed folder, then read the csv into a dataframe outside the function:
import pandas as pd
folder_path = folders
my_csv = os.path.join(folder_path, "my_file.csv")
df = pd.read_csv(my_csv)
