Converting a dataframe to json and writing it to a File & appending a new Dataframe to that file
I need to write a Dataframe, converted to JSON format, to a file . This can be done quite easily with a one liner
df.to_json() . Problem arises when I write it to a file because I need to append to the same file other dataframe as well.
How it can be done efficiently
I am writing to the file using dataframe method
Now if I have another dataframe to be added to this file only then how it can be achieved (without loading it to memory)
