Does anyone know sed -i implementation?
When I executing sed with -i option (replace file) against very large file, is there any way to know how about target file processed. e.g. creating intermediate file at /tmp , or processed on the memory and swapped etc.

strace shows that even for small files the original file is read, the results are written to a temporary file and then renamed to the name of the original file.
So I would assume that this is the same behaviour for larger files: a temporary file will be created.
