In the execution of scatter gather, the "sleep 2 sec" Flow Reference takes about 2 sec to complete, and the "sleep 8 sec" Flow Reference takes about 8 sec to complete.
About how many sec does it take from the Scatter-Gather is called until the "Set Payload" transformer is called?

Wait, are we sure it's not 10 seconds?

Totally agree, the longest one dictates the time.

Nope, definitely 8 seconds, that's how scatter-gather works.

I thought it would be less, but I guess it makes sense!

It takes 8 seconds total.

I feel like it could be 2 seconds since the first one finishes quickly, but I guess the longest one matters here.

I practiced a similar question, and I think it was about the longest duration too. So, I would go with 8 seconds.

I'm not entirely sure, but I think the "Set Payload" transformer waits for all references to finish, so maybe it’s 10 seconds?

I remember that in scatter-gather, the longest flow reference determines the total time, so it should be 8 seconds.

I think I've got this! The "Set Payload" transformer is called after both the 2-second and 8-second references have completed, so the total time should be 8 seconds.

I'm a bit confused by the scatter-gather concept here. I'll need to review my notes to make sure I understand how the timing works.

Okay, let me think this through step-by-step. The "sleep 2 sec" and "sleep 8 sec" references take 2 and 8 seconds respectively, so the total time should be somewhere in between.

Hmm, this looks like a tricky one. I'll need to carefully walk through the flow to figure out the timing.

Oh, I see. So the correct answer is C) 2.

But the 'Set Payload' transformer is called after the 'sleep 2 sec' Flow Reference, so it should be 2 seconds.

Wait, so the 'Set Payload' transformer is like the alarm clock that wakes up the flow references after their beauty sleep? D) 10 seconds sounds about right to me.

D) 10

A) 8

I believe it takes 8 seconds.

Haha, looks like the 'sleep 2 sec' and 'sleep 8 sec' flow references are taking a nice nap while we figure out the answer. I guess D) 10 is the way to go here.

Exactly, the Scatter-Gather will wait for all flow references to complete before moving on.
KE

Oh, that makes sense. So it doesn't matter how long the other flow references take.

I think it's actually B) 0 because the 'Set Payload' transformer is called immediately after the Scatter-Gather.

This is a straightforward question. The 'sleep 2 sec' and 'sleep 8 sec' flow references clearly indicate that the total time taken is 10 seconds. D) 10 is the correct answer.

Great, so we all agree on D) 10 as the answer
AN
Annamae

Yes, it makes sense because 2 sec + 8 sec = 10 sec
HA

I think the answer is D) 10

I think it takes 10 seconds.

If the 'sleep 2 sec' and 'sleep 8 sec' flow references take 2 and 8 seconds respectively, then the total time for the scatter-gather process should be 10 seconds. Therefore, the answer is D) 10.

So the answer is D) 10.

Yes, it should be 10 seconds since the 'sleep 2 sec' and 'sleep 8 sec' flows take that long.
