Functions ¶

func Backfill ¶

func Backfill(ctx context.Context) error

Backfill is a one-time versioned migration, never a periodic table scan.

func Rebuild ¶

func Rebuild(ctx context.Context, progress func(int64)) (int64, error)

Rebuild explicitly visits a bounded snapshot of all topic IDs, including dormant topics. It preserves first publication timestamps and supports reruns.

func Recalculate ¶

func Recalculate(ctx context.Context, id uint64, now time.Time) error

Recalculate is the explicit rebuild entry point. Normal worker processing already has the task version and goes straight to recalculateScheduled.

func Score ¶

func Score(s Signals, published, now time.Time) (int64, *time.Time)

Score performs fixed-cost integer arithmetic over one topic's saved values.

func StartWorker ¶

func StartWorker()

StartWorker runs at most once in this process. Shared-database deployments must enable it on only one instance; it does not acquire distributed leases.

Types ¶

type Signals ¶

type Signals struct {
	Likes, Replies uint64
	LastPostedAt   *time.Time
}

Signals contains only counters and timestamps already persisted on topics.
