  • Ticket #2959 – Description

    initial v1  
    33One problem is favorites & subscriptions are currently stored per-user, serialized in `wp_usermeta`. The reasoning for this originally, was that this meta-data was specific enough to the user that it was okay to keep there.

    5 Another problem is querying for which user IDs are subscribed to which forums or topics requires a specific `FIND_IN_SET` MySQL flag, which ends up transversing those serialized `wp_usermeta` values looking for post IDs. Yuck.

     7This logic fails hard with Notifications: when replying to a topic or creating a new topic in a forum, querying for all subscribed users to notify them via email, is a query that does not perform very well when there are millions of rows in `wp_usermeta`.

    79So we have two problems that are very uncharacteristic of bbPress's heritage: performance, simplicity.
