As discussed in previous blog post, drush cron can be run from crontab too. While seeming pretty straightforward, trying it out caused some troubles.

The thing you would do to make drush run from crontab is:

$ crontab -e
* * * * * drush -r /path/to/drupal

Also tried to give full path to drush install

$ crontab -e

By big imports I mean creating millions of nodes and indexing them fo apache solr search. We needed to import 1 million records from file, 3 nodes for each record, one in each of our 3 languages. These nodes also had 3 taxonomy vocabularies, around 30 cck fields and we also needed to join another table containing a spatial coordinates for our geo field.
