Synchronization

Unfettered parallelism empowers your workflow to aggressively carry out its tasks without being concerned about what other activities it may be carrying out simultaneously. However, sometimes those parallel threads of activity relate to each other in important ways. Sometimes a service needs to obtain results from multiple different branches before it can run.

When multiple separate branches need to weave back together, or concurrent activity needs to be gathered up, we call that synchronization.

This chapter will explain how to synchronize the parallel or concurrent activity within your workflow using various builtin mechanisms.
