📌How efficiently we can read the large CSV files will get a detailed picture.
Solution 1:
Split the large file in to smaller chunk: If you are doing it with java we need to traverse entire file.
After splitting read each file with separate thread: Here again we will traverse the each file.
So this solution is not affective as two times we are traversing the file the time will be approximately double.
Solution 2 (effective way): Watch the video.
