Enable/disable post revisions programmatically

Question

Is there a way to temporarily disable revisions.... I have noticed that wp_update_post is very slow and creates revisions I don't need. The fix could be to disable revisions before issuing wp_update_post and re-enable the feature once done....

Answer 1

Seems this will do the job:

remove_action('pre_post_update', 'wp_save_post_revision');// stop revisions

and

add_action('pre_post_update', 'wp_save_post_revision');//  enable revisions again

Answer 2

Easiest way is to set WP_POST_REVISIONS contant to false, additional information about post revision management
