stats

func Clear ¶

func Clear(ctx context.Context) error

Clear deletes previously-computed stats from datastore and memcache.

func Get ¶

func Get(ctx context.Context, live bool) (*common.Stats, error)

Get returns stats that were previously computed by the Update method. If live is true, new stats containing only current entity counts will be returned instead.

func Update ¶

func Update(ctx context.Context) error

Update reads all songs and plays and saves stats to datastore.

This uses projection queries, which are counted as "small" datastore operations and are free in most (all?) regions, but it's still slow and should be called periodically by a cron job instead of interactively.
