Changeset 11101 for trunk/src/bp-members/bp-members-cache.php

Message:

Activity: Invalidate query caches when a user's 'last_activity' is updated.

User 'last_activity' is stored in the activity table, but not updated
via the Activity API, so regular invalidation techniques do not work.

In addition, 'last_activity' is quite frequently updated, meaning that
the activity query cache becomes less valuable. To mitigate this, the
current changeset separates the cache for queries containing
'last_activity' from the cache for those that do not.

Fixes #7245.
