AWS Step Function
My problem is to how to sendTaskSuccess or sendTaskFailuer to Activity which are running under the state machine in AWS .
My Actual intent is to Notify the specific activities which belongs to particular State machine execution.
I successfully send notification to all waiting activities by activityARN. But my actual need is to send notification to specific activity which belong to particular state machine execution .
Example . StateMachine - SM1 There two execution on going for SM1-- SM1E1, SM1E2 . In that case I want to sendTaskSuccess to activity which belongs to SM1E1 .
follwoing code i used . But it send notification to all activities
GetActivityTaskResult getActivityTaskResult = client.getActivityTask(new GetActivityTaskRequest()
.withActivityArn("arn detail"));
if (getActivityTaskResult.getTaskToken() != null) {
try {
JsonNode json = Jackson.jsonNodeOf(getActivityTaskResult.getInput());
String outputResult = patientRegistrationActivity.setStatus(json.get("patientId").textValue());
System.out.println("outputResult " + outputResult);
SendTaskSuccessRequest sendTaskRequest = new SendTaskSuccessRequest().withOutput(outputResult)
.withTaskToken(getActivityTaskResult.getTaskToken());
client.sendTaskSuccess(sendTaskRequest);
} catch (Exception e) {
client.sendTaskFailure(
new SendTaskFailureRequest().withTaskToken(getActivityTaskResult.getTaskToken()));
}
I did a POC to check and below is the solution .
if token is consumed by getActivityTaskResult.getTaskToken() and if your conditions not satisfied by request input then you can use below line to avoid token consumption .awsStepFunctionClient.sendTaskHeartbeat(new SendTaskHeartbeatRequest().withTaskToken(taskToken))
