Feed import of 20,000 nodes. How to batch up 1000 at a time? I setup my Drupal 7 feed importer to import from a csv file with 20,000 nodes. I'm able to get it working with 20 nodes just to test to make sure everything is working. But is there a setting to be able to process X amount of nodes at once? My csv file is 12MB and I'd like to just do 300 at a time, but I don't see an option for this anywhere.

How would I make it process a set amount?
Which version of Drupal are you using? I haven't checked on Feeds for Drupal 8, but Feeds for Drupal 7 (unless it's changed in the last few years) has a hard-coded item limit of 50. If you're importing from a CSV, your node architecture is probably pretty simple. You could try the Feed Import module instead of Feeds, in my experience it's better suited for very large imports.
