Create an API from EDA or ML outcome?

I have the following sample dataset (the actual dataset is over 10 million records)




Passenger Trip
0 Mark London
1 Mike Girona
2 Michael Paris
3 Max Sydney
4 Martin Amsterdam
5 Martin Barcelona
6 Martin Barcelona
7 Mark London
8 Mark Paris
9 Martin New york
10 Max Sydney
11 Max Paris
12 Max Sydney
...
...
...


And I wanted to get the destination frequently travelled by a passenger !



I was playing around in Jupyter and got the expected data with the following approach





series_px = df_px_dest.groupby('Passenger')['Trip'].apply(lambda x: x.value_counts().head(1))

df_px = series_px.to_frame()

df_px.index = df_px.index.set_names(['UName', 'DEST'])

df_px.reset_index(inplace=True)

def getNextPossibleDestByUser(pxname,df=df_px):
return df.query('UName==@pxname')['DEST'].to_string(index=False)


While the response is fine. I have few doubts now



1) What's the best way to expose the method (say in this case getNextPossibleDestByUser) as a API (pass customer name as input and get the destination as output) ?



2) Whenever the API is being called , does that mean all the 10 million records gets processed each time ? Are there anyway to optimise that ?



3) Rather than dataframe (pandas) query approach can I consider some ml models or utility functions from say scikit to solve the same problem ?
