Actions related to Activities

The following are actions that are performed by activity workers:

Activity workers use the PollForActivityTask to get new activity tasks. After a worker receives an activity task from Amazon SWF, it performs the task and responds using RespondActivityTaskCompleted if successful or RespondActivityTaskFailed if unsuccessful.

Deciders use PollForDecisionTask to get decision tasks. After a decider receives a decision task from Amazon SWF, it examines its workflow execution history and decides what to do next. It calls RespondDecisionTaskCompleted to complete the decision task and provide zero or more next decisions.
