Documentation Request: How to generate missing derivative files on backend

[misilot]

Hello,

I'm hoping I didn't miss it somewhere, but how would go about generating derivative files for objects in the system? For example we ingested >10,000 items, but something went wrong where the thumbnails and other items haven't been generated yet. So we want to just kick it off in the background / foreground would be great as well, so we can watch and check progress.

Thanks!

You can create a view to show the objects in question, add a field for Node operations bulk form and you're pretty much done.

There is no real way to track progress short of tailing the log of whatever microservice is building the derivatives.

You can set the pager to handle as many objects at a time as you like, but the default php.ini setting only allows 1000 variables, so you might want to stick to about 900 per page.

Thanks @ajstanley, so just want to confirm there is no way to kick this off as a cronjob? :(

From @seth-shaw-unlv this gist should work from the Tech Call
