 Statistics
 ==========
 =====================
 Repository statistics
 =====================
 The Kallithea statistics system makes heavy demands of the server resources, so
 in order to keep a balance between usability and performance, the statistics are
 cached inside db and are gathered incrementally. This is how Kallithea does
 this:
 Kallithea has a ``repository statistics`` feature, disabled by default. When
 enabled, the amount of commits per committer is visualized in a timeline. This
 feature can be enabled using the ``Enable statistics`` checkbox on the
 repository ``Settings`` page.
 With Celery disabled
 --------------------
 The statistics system makes heavy demands on the server resources, so
 in order to keep a balance between usability and performance, statistics are
 cached inside the database and gathered incrementally.
 When Celery is disabled:
 - On each first visit to the summary page a set of 250 commits are parsed and
   updates statistics cache.
 - This happens on each single visit to the statistics page until all commits are
   fetched. Statistics are kept cached until additional commits are added to the
   repository. In such a case Kallithea will only fetch the new commits when
   updating its cache.
   On each first visit to the summary page a set of 250 commits are parsed and
   added to the statistics cache. This incremental gathering also happens on each
   visit to the statistics page, until all commits are fetched.
 With Celery enabled
 -------------------
   Statistics are kept cached until additional commits are added to the
   repository. In such a case Kallithea will only fetch the new commits when
   updating its statistics cache.
 - On the first visit to the summary page Kallithea will create tasks that will
   execute on Celery workers. This task will gather all of the stats until all
   commits are parsed, each task will parse 250 commits, and run the next task to
   parse the next 250 commits until all of the commits are parsed.
 When Celery is enabled:
 .. note::
    At any time you can disable statistics on each repository via the repository
    edit form in the admin panel. To do this just uncheck the statistics checkbox.
   On the first visit to the summary page, Kallithea will create tasks that will
   execute on Celery workers. These tasks will gather all of the statistics until
   all commits are parsed. Each task parses 250 commits, then launches a new
   task.
