Is it possible to displays live information in h2o apps like what we have in scripts?

Hi
for my recent project I need to write a dashboard that is both interactive and shows live information(update a table every second) at the same time , is there any way to do it ?
thanks

Hi @mortezaomidi24.

The mechanism for periodic data updates is same for apps and scripts. Our dashboard example uses a simple infinite loop with time.sleep. The same can be used for Wave apps, but in a real-world scenario you might want to run the periodic part in a separate python thread instead.

Thank you so much ,
I got the idea but couldn't write a proper code for it, is there any example code to do it?
Like dashboard example, i can write a loop for updating data in a script but in app it didn't work for me

Have a look at our site_async example.

Do we need to use a separate python thread because with a single thread time.sleep will hang the application?

Yes, either threads, processes or asyncio. See the docs and this detailed blog post.
