Hmm, that doesn’t seem to fix the issue unfortunately @angus. There’s a lot of actors, possibly, in the DB, and the batching is still insufficient.
On meta, for example, there are 90k+ rows in that model:
discourse(prod)> DiscourseActivityPubActor.where(domain: 'mastodon.social').size
=> 90264
Do we absolutely need to update their available column on every delivery?
