<p>Hi,</p>
<p>I noticed that when running processing algorithms and also models, that both the in between results, but also end results are only kept in memory and the end result ends up as memory layer, if I use the Option "Create Temporary Layer".</p>
<p>I'd like to better understand how QGIS processing works. What happens in such a case if the data is really, really big? Would it crash the machine, or switch from memory layer to a real file "automagically"? If yes, how would this be decided? Or is it the responsibility of the OS to swap such really large temporary layers into files, without the user noticing?</p>
<p>Or is the user responsible for that and needs to switch to a file as the output instead of the option "Create temporary layer"?</p>
<p>In my opinion, the term "Create temporary layer", from a user perspective, doesn't necessarily mean "Create Memory layer". A temporary layer could also be stored in disk.</p>
<p>Thanks for shedding some light on the behaviour of processing!</p>
<p>Andreas</p>
