[QGIS-Developer] Processing: sort algorithm not working?

[Andreas Neumann]

Hi,

I have a model where at the very end before adding it to the project I was
trying to sort the result with an expression.

But: the sorting doesn't work. In the help there is the cryptic hint at
https://docs.qgis.org/3.10/de/docs/user_manual/processing_algs/qgis/vectorgeneral.html#qgisorderbyexpression
that "Be careful, it might not work as expected with some providers, the
order might not be kept every time."

Does someone know more about it? Which providers specifically do not
support sorting?

Does this statement apply to the reading provider or the writing provider?

In my case, I never got any correct sorting ...

Thanks,
Andreas
