So, I have this CSV that has been properly parsed into JSON format. I have the right conditions under an apply to each to recognize if the first character is a number, if the whole thing is 3 characters and has the last condition that it starts with 1,2,3,4,7,9 and then counts the specific department numbers. The issue is, the apply to each is taking ages. Is there a way to circumvent apply to each or speed it up? the degree of parallelism is up to 35 atm also
