Hello
I have a big file after making changes in ram I need to write it back to
disk.
I know for text file store it's written line by line.
But is there any better storage type for high performance read/writing?
maybe binary?
Thank you.

Do you have the option to "seek" to the correct place in the file to make your
changes? For example, perhaps:
- Your changes are few compared to writing out the whole file
- Your changes do not change the size of the file (or you can pad line-end with
spaces)
It is an edge case, but just a tho

That sounds positive. You should be able to avoid most of the overhead of
writing the file. The general idea is that you are "updating in place" rather
than writing out the whole file.
Something like below is what I was thinking, but it isn't tested! Make sure
you have a copy of your input

I am not sure,
what does this mean? not changing the line length?
but in most case I need to change the length of a line.
Thanks again.

This is where you need to pad spaces. So, for example:
- old: "I am young and fast\n" (20 bytes)
- new: "I am old and slow\n" (18 bytes)
The second version is shorter, so it will need two spaces before the newline:
- new: "I am old and slow__\n" (20 bytes; I put "_" instead of a space)
