Straggler?

Hallo Zusammen?

As far as I could figure out that Straggler is the degradation of performance. isn't? Because performance is based on completion. So, Either re-execution or faulty Hardware might be propagated, Straggler. Is it correct? Is there any other reason for Straggler?

Dank im Voraus

In MapReduce, worker nodes that are slow, i.e. they need much more time to finish the computation compared to other nodes, are called "stragglers".
