Barriers

Barriers are a mechanism which synchronize tasks in the same group.

An implicit barrier ensures that all tasks being execution at the same time, eliminating time gaps caused by initialization steps such as image pulling and input data downloading.

Hint

Implicit barriers are enabled by default.

To disable the implicit barrier, set the barrier field to false in the group spec.
