    Fix N+1 query when displaying events · c52a36e8
    Yorick Peterse authored
    When displaying events we would load the target of those events, then
    render the entire data using our Markdown pipeline. This pipeline would
    eventually request the author of every target, leading to an additional
    query being executed for every target to get the author.
    To fix this we now eager load the author of the event's target. In my
    local environment this reduces the number of queries to display a
    project's Atom feed from 40 to 24 queries.
