The Revision Snip module provides a utility to prune node revisions that are older than a certain number of days from the database. At some point in the lifetime of most Drupal 7 sites, revision storage becomes a source of database bloat. This module provides a simple utility for site owners to be able to perform a customized one time pruning of these revisions through the GUI or via drush.
The drush utilities optionally integrate with Drush Multi Processing, a plugin allowing for multi-threaded drush commands. This is especially useful in sites where revision bloat is exceptionally large.
Further development
If you read the Similar Projects section in the Node Revision Delete module you will see that at this moment there are 10 modules that works with the Cleanup of Revisions:
- Node Revision Bulk Delete
- Node Revision Cleanup
- Revisionator
- Node Revision Restrict
- Revision Deletion
- Node revisions autoclean
- Revision disintegrate
- Revision Purger
- Revision Snip
- Node Revision Delete
We don't need all these modules to clean revisions when we can have only one, is more easy to maintain and we can concentrate efforts, the only module that is being migrated to Drupal 8 is [#2866825] and at the same time the new features are backported to the 7.x-3.x version. So, we recommend you to use the Node Revision Delete module.
