AFAIK document update handlers run before the document is created/updated, so I guess it would
just work for your use case.

to achieve that ? My _view is giving me all records with = "test", but which of those
"test" documents is last? I can use date ofc. But using date as criteria is dangerous since
date is outside server logic. Something/someone can change it. So last documents will not
be last.

You could use a document update handler to have the server set a last modified date property
on your documents. You could also maybe just query the _changes feed for a database: /<database>/_changes?limit=1
