目前，我正在尝试通过提高不同Dispatcher和上下文的使用来优化应用性能。我偶然发现的一个问题是，如果我在带有IO Dispatcher的协程中启动一个suspend函数，其他函数是否也会在同一个Dispatcher中执行？

示例

fun doSomething() {
    viewModelScope.launch(Dispatchers.IO) {
       getUserData(viewModelScope)
    }
}

fun getUserData(innerScope: CoroutineScope) {
    workerList.startUserDataWorker()
    observeUserData(innerScope) // suspend function, is this called inside the IO Dipatcher?
}

// Will this be called inside the IO Dispatcher?
private suspend fun observeUserData(innerScope: CoroutineScope) {
    observerWorkerStateAndPassData(workerList.userDataWorkInfo, USER_DATA_OUTPUT_OPTION).collect { status ->
        when(status) {
            is Status.Loading -> {
                _userDataState.postValue(Status.loading())
            }
            is Status.Success -> {
                 // Will getShippingAddressList() also be called on the IO Dispatcher?
                _userDataState.postValue(Status.success(getShippingAddressList()))
            }
            is Status.Failure -> {
                _userDataState.postValue(Status.failed(status.message.toString()))
            }
        }
    }
}

// Getting Address from the local room cache. Is this called on the IO Dispatcher?
private suspend fun getShippingAddressList(): List<UserDeliveryAddress> {
    val uncachedList = userAddressDao.getAllAddress(UserAddressCacheOrder.SHIPPING)
    return userAddressCacheMapper.mapFromEntityList(uncachedList)
}
