Efficient Way to Read SAS file with over 100 million rows into pandas
Maybe you don't need your entire file to work on it so you can take 10%. You can also change your variable types to reduce its memory.

if you want to store a df and re use it instead of re importing the entire file each time you want to work on it you can save it as a pickle file (.pkl) and re open it by using pandas.read_pickle
I have an SAS file that is roughly 112 million rows. I do not actually have access to SAS software, so I need to get this data into, preferably, a pandas DataFrame or something very similar in the python family. I just don't know how to do this efficiently. ie, just doing df = pd.read_sas(filename.sas7bdat) takes a few hours. I can do chunk sizes but that doesn't really solve the underlying problem. Is there any faster way to get this into pandas, or do I just have to eat the multi-hour wait? Additionally, even when I have read in the file, I can barely do anything with it because iterating over the df takes forever as well. It usually just ends up crashing the Jupyter kernel. Thanks in advance for any advice in this regard!
