Action datatables should use integer indexes rather than string indexes (smaller size and faster access) #1600

Currently datatables for Actions are indexed with the metrics string (nb_visits, nb_hits, etc.). See code in plugins/Actions/Actions.php archiveDay()

Other datatables are using integer indexes, mapping is defined in Piwik_Archive::$mappingFromIdToName

Actions datatable should use a similar integer mapping to reduce size of Actions datatables, and make querying faster.


thanks to halfdan run of xhprof, we now know that this is indeed very costly, lets fix it


(In [3696]) Page titles report improvements fixes #1898

  • new fields in 2 log tables (major schema upgrade in next release!)
  • code refactored and optimized, (only the UI to display top entry/exit page titles is missing)

Performance improvements

  • Actions Archiving is much more efficient, removed many JOINs and updating algorithm so that we select and parse action names only once per action.
  • Fixes #1600: datatables now indexed by int, no data migration but code works with both old and new data structure
  • Fixes #1780: new index

Improvements to integration tests

  • never loads the Provider plugin in proxy-piwik.php since reverse ip lookup slows up tests a lot
  • fixing a test result that were previously incorrect (_withCookieSupport) because a static cache wasn't cleaned after each test
@mattab mattab added this to the Piwik 1.2 milestone
