ℹ️ Important: Docs version tagging👋 Thanks for updating the docs! Just a friendly reminder that our docs are now cumulative. This means all 9.x versions are documented on the same page and published off of the main branch, instead of creating separate pages for each minor version. We use applies_to tags to mark version-specific features and changes. Expand for a quick overviewWhen to use applies_to tags:✅ At the page level to indicate which products/deployments the content applies to (mandatory) What NOT to do:❌ Don't remove or replace information that applies to an older version 🤔 Need help?

I think we need to update this doc?

This is meant to demonstrate how easy it is to convert boolean to integer in order to comply with PromQL in the future. We discussed these tests with @kkrik-es today and I added them and added one as an example to the documentation. Perhaps adding these examples was unnecessary? WDYT
Here is how it looks:
FROM employees
| WHERE emp_no == 10020
| STATS is_present = TO_INTEGER(PRESENT(languages))
;
is_present:integer
0
;

Ah, I missed that. Thanks for explaining.

Can we add a serialization test or remove serialization support for this class? I don't think we serialize this class.

Great, this function now supports downsampled data :)

Add a new ES|QL PRESENT_OVER_TIME function that is similar to PRESENT, but is used to check the presence of values over a time series in the given field.
This has to be merged after #133986
