Onboarding/lifecycle workflows in PostHog (and downstream tools like SendKit)
need to segment users by how many social accounts they've connected and how
many posts they've created. The existing SyncUser job only re-emitted these
counts on signup and billing changes, so the values went stale the moment a
user did anything meaningful.
This wires up two new paths that refresh the account group automatically:
- SocialAccountObserver (#[ObservedBy] on the model) fires SyncAccountUsage
on created/deleted, covering all 14 OAuth callback paths in one hook.
- SyncUsageOnPostCreated / SyncUsageOnPostDeleted listeners (auto-discovered)
fire SyncAccountUsage on the corresponding events dispatched by CreatePost
and DeletePost.
SyncAccountUsage is the new dedicated job for group properties only
(groupIdentify account + workspace). SyncUser was slimmed to just identify
the user and delegate the group sync, removing the duplicated property
mapping between the two jobs.
All entry points (observer + both listeners) short-circuit when PostHog is
disabled, so self-hosted instances without PostHog configured see zero
queued jobs and zero overhead.
posts_count cache is invalidated before each sync so the job reads fresh
counts from the database instead of stale cached values.
