Query client on SSR memory

Does anyone know if this

function CustomApp({ Component, pageProps }: AppProps<AdditionalAppProps>) {
  const [queryClient] = React.useState(
    () => new QueryClient({
        defaultOptions: {
          queries: {
            refetchOnWindowFocus: false,
            refetchInterval: false,
            refetchIntervalInBackground: false,
          },
        },
      })
  );

function CustomApp({ Component, pageProps }: AppProps<AdditionalAppProps>) {
  const [queryClient] = React.useState(
    () => new QueryClient({
        defaultOptions: {
          queries: {
            refetchOnWindowFocus: false,
            refetchInterval: false,
            refetchIntervalInBackground: false,
          },
        },
      })
  );

Would create a new object in nextJS for each session? on a standard react app that object would be created each time a component renders. Wasn't sure for next as this is app component. Anyone know?
