Durable Functions - Awaitable Tasks inside Activity Function

I have a durable function that has inputs determined by a previous activity function For each activity function I have multiple awaitable tasks where each task is dependent on the previous task's output.

This is my structure as follows:

Orchestrator

[FunctionName("MessageController")]

public static async void Run(

[OrchestrationTrigger] DurableOrchestrationContext context,

TraceWriter log)

{

if (!context.IsReplaying) log.Warning("MessageController started");

var Input1= context.CallActivityAsync<ResultMessage>("Function_1", new InputMessage());

var Input2= context.CallActivityAsync<ResultMessage>("Function_2", Input1);

var Input3= context.CallActivityAsync<ResultMessage>("Function_2", Input2);

}

Activity Function

[FunctionName("Function_1")]

public static ResultMessage Run(

[ActivityTrigger] DurableActivityContext activityContext,

TraceWriter log)

{

//Awaitable task

var taskOutput= await DoSomething();

//Awaitable task

var token = await DoAnotherThing(taskOutput);

}

I have tested MindMajix Microsoft Azure this and all works fine. But i ma wondering if this is good practice? Is it normal to have awaitable tasks within an activity function for a durable function?
