/AWS1/CL_SFN=>GETACTIVITYTASK()¶
About GetActivityTask¶
Used by workers to retrieve a task (with the specified activity ARN) which has been
scheduled for execution by a running state machine. This initiates a long poll, where the
service holds the HTTP connection open and responds as soon as a task becomes available (i.e.
an execution of a task of this type is needed.) The maximum time the service holds on to the
request before responding is 60 seconds. If no task is available within 60 seconds, the poll
returns a taskToken with a null string.
This API action isn't logged in CloudTrail.
Workers should set their client side socket timeout to at least 65 seconds (5 seconds higher than the maximum time the service may hold the poll request).
Polling with GetActivityTask can cause latency in some implementations. See
Avoid
Latency When Polling for Activity Tasks in the Step Functions Developer Guide.
