ViewsI need to process a CSV file with ~12 million rows. Each row has ~20 columns. Currently using pandas:
df = pd.read_csv('huge_file.csv')
result = df.groupby('category').sum()
This loads everything into memory and crashes on my 8GB machine. What are the best alternatives? I've heard about chunking and Polars but not sure which to start with.
