wso2 esb iterate mediator thread safe?

Question

I have below iterate Seq,

  <iterate attachPath="//Test"
    expression="///Test" preservePayload="true">
    <target>
      <sequence>
       <header name="Action" scope="default" value="action1"/>
       <send>endpoint 1</send>
      </sequence>
    </target>
    <target>
      <sequence>
       <header name="Action" scope="default" value="action2"/>
       <send>endpoint 2</send>
      </sequence>
    </target>
  </iterate>

so does the "Action" is thread safe in each iterate target\seq.

if so, in"aggregate", can i access the property/header inside the target\seq?

iterate is parallel, in target\seq have same header name "Action", so if in the first target\seq set to "Action" to "action1", second target\seq is using this value. — James
Actually, I did't get what you said. 'SOAP Action' is a SOAP Header to specify the required action to be executed out of the list of available actions with a WSDL end-point right? Can you please elaborate from there? — Supun Wijerathne
Yes, this action is for WSDL end-point operations. Different call/operations should have different action. — James

I am not sure whether its thread safe. But to workaround your doubt, I think the following information would help.

There is a property called "Sequential Mediation" in the iterate mediator. If it is set to true, it will process the iterated messaged sequentially. See the following documentation. https://docs.wso2.com/display/ESB490/Iterate+Mediator
