After digging into this problem, the log was produced by heartbeat, because the graph keeps loading data from meta service. This shows that the meta service is frequently updated by the request from the storage service.

bool MetaClient::loadData() {
  if (options_.role_ != cpp2::HostRole::UNKNOWN &&
      localDataLastUpdateTime_ == metadLastUpdateTime_) {
    return true;
  }

Expected behavior
