To get multiple records for a child runID use a hash of arrays (HoA)

#!/usr/bin/perl
use strict;
#use Data::Dump 'pp';

my %data = ();
my @id   = ();
my $reqid = '8274';

my $infile  = 'worker.log';
my $outfile = 'data.CSV';
open IN,'<',$infile or die "$!";

# input
while (<IN>) {
  chomp;
  next unless /Task:id=(\d+)/;

  my $taskid = $1;
  my (undef,$timestamp,undef)  = split /\s+/,$_,3;
  
  if (/(Started|Done).+topic (\d+_(\d+)_\d+_IN_(\d).*)/){
    #print "$1 $2 $3 $4\n";
    $data{$3}[$4]{$1}      = $timestamp;
    $data{$3}[$4]{'Topic'} = $2;
  }

  while ( /\{(\d+)-SUCCESSFUL\}/g ){
    push @id,$1 if ($taskid eq $reqid);
  }
}
close IN;
#pp \@id;
#pp \%data;

# output
open OUT,'>',$outfile or die "$!";
my @cols = qw(Topic Started Done);
printf OUT "%s,%s,%s\n",@cols;
for my $id (sort @id){
  if (exists $data{$id}){
    for my $rec ( @{$data{$id}} ){
      printf OUT "%s,%s,%s\n", map { $rec->{$_} } @cols;
    }
  }else {
    print OUT "$id- no data\n";
  }
}
close OUT;
