QUESTION
I have 2 csv files of multiple fields(approx 30 fields), and huge size ( approx 4GB ).
...ANSWER
Answered 2020-May-31 at 18:18Storing data of such magnitude in database is most correct approach to tasks of this kind. At minimum SQLlite is recommended but other databases MariaDB, MySQL, PostgreSQL will work quite well.
Following code demonstrates how desired output can be achieved without special modules, but it does not take in account possibly messed up input data. This script will report data records as different even if difference can be just one extra space.
Default output is into console window unless you specify option output.
NOTE: Whole file #1 is read into memory, please be patient processing big files can take a while.
