How can I handle large data sets efficiently in Perl

Handling large data sets efficiently in Perl involves using appropriate data structures, employing memory management techniques, and utilizing built-in modules optimized for performance. Below is an example illustrating how to process a large file in chunks, which can help reduce memory usage.


        #!/usr/bin/perl
        use strict;
        use warnings;

        my $filename = 'large_data.txt';

        # Open the file for reading
        open my $fh, '<', $filename or die "Cannot open $filename: $!";

        # Process the file in chunks
        while (my $line = <$fh>) {
            # Process the line (For example, printing)
            print $line; 
        }

        close $fh;
