Hello,
I’m looking for an efficient way in Spark to search for a series of telephone
numbers, contained in a CSV file, in a data set column.
In pseudo code,
for tel in [tel1, tel2, …. tel40,000]
search for tel in dataset using .like(« %tel% »)
end for
I’m using the like function because the telephone numbers in the data set main
contain prefixes, such as « + « ; e.g., « +3312224444 ».
Any suggestions would be welcome.
Many thanks.
Philippe
