Reescribe el siguiente código documentándolo:

private async Task SetAndGetKeysPipelineBacth(int quantity, StringDTO testStringDTO)
		{
			var salt = Guid.NewGuid().ToString();
			var stopwatch = new Stopwatch();
			stopwatch.Start();
			var batch = _db.CreateBatch();
			var tasks = new List<Task>();
			for (int i = 1; i <= quantity; i++)
			{
				var instructorNameKey = new RedisKey($"instructors:{salt}_{i}:name");
				tasks.Add(batch.StringSetAsync(instructorNameKey, $"Instructor Name {salt}_{i}"));
				tasks.Add(batch.StringGetAsync(instructorNameKey)
					.ContinueWith(x => testStringDTO.Instructors.Add($"{x.Result}")));
			}

			batch.Execute();
			await Task.WhenAll(tasks);
			stopwatch.Stop();
			testStringDTO.TimeSeconds = stopwatch.Elapsed.TotalSeconds.ToString(CultureInfo.InvariantCulture);
		}
