This can be significantly faster with a pandas UDF, note, because you can
vectorize the

Hi
We are using a haversine distance function for this, and wrapping it in
udf.
from pyspark.sql.functions import acos, cos, sin, lit, toRadians, udf
from pyspark.sql.types import *
def haversine_distance(long_x, lat_x, long_y, lat_y):
return acos(
sin(toRadians(lat_x)) * sin(toRadia
Hi All,
I have a requirement to calculate distance between four coordinates(Latitude1,
Longtitude1, Latitude2, Longtitude2) in the pysaprk dataframe with the help of
from geopy import distance without using UDF (user defined function),Please
help how to achieve this scenario and do the needful.
