As you sort by first field anyway, could you please try out omitting field split (-t, -k1)? For me it gives a noticeable improvement:

$ stat --printf="%s\n" p.csv

1258291200

$ time sort -t, -k1 -S100% -o sorted.csv p.csv

real 0m50,186s user 4m6,962s sys 0m4,562s

$ time sort -o sorted.csv p.csv

real 0m43,483s user 3m36,473s sys 0m4,282s

Arbitrary length string of null characters also produces zero hash, e.g.: System.out.println("\0\0\0\0\0".hashCode());

Writing code is not a problem, changing it without breaking is. Taking tech debt is not a problem, paying interest on it is.

And you will hardly hire a lawyer to work in unknown to him legal domain in foreign country in foreigh language.
