Preview and transfer enhancements: TERMINALFOUR t44u 2013

  1. 1. The Aviva Stadium Dublin, 21-22 November 2013
  2. 2. As promised last at t44u 2012… Preview & Publish Improvements • Incremental • Improved caching • More efficient coding practices t44u 2013 2
  3. 3. Preview & Publish Improvements • Not all automatic t44u 2013 3
  4. 4. Preview & Publish Improvements • Who knows about the Cache Handler? • May be available at SiteManager?ctfn=cache t44u 2013 4
  5. 5. Preview & Publish Improvements • The Cache Handler enables elements within Content Types to be “pre-cached” t44u 2013 5
  6. 6. Preview & Publish Improvements • A Top Content navigation object shows the 5 latest news articles ordered by a date element within the Content • Keyword Search Content navigation object finds related news articles, based on a keywords element within the Content t44u 2013 6
  7. 7. Preview & Publish Improvements • How does it do this? t44u 2013 7
  8. 8. Preview & Publish Improvements • It loads each piece of Content from the database to check the Date or Keywords t44u 2013 8
  9. 9. Preview & Publish Improvements • What if you’ve an archive of 1,000 news articles? t44u 2013 9
  10. 10. Preview & Publish Improvements • You wait… t44u 2013 10
  11. 11. Preview & Publish Improvements • …unless the Date or Keywords are “precached” t44u 2013 11
  12. 12. Preview & Publish Improvements • This was only the case with certain Navigation Objects (Keyword Search Content, Top Content) • Since version 7.4 of TERMINALFOUR Site Manager, this is now extended to all areas of the publish engine t44u 2013 12
  13. 13. Preview & Publish Improvements • Content is ONLY loaded from the database IF the requested elements aren’t pre-cached t44u 2013 13
  14. 14. Previous Transfer Mechanism • Transfer was a two-step process • Generate / check file hashes • Upload modified files t44u 2013 14
  15. 15. Previous Transfer Mechanism • Shortcomings • It was a two-step process • Subsequent publish could alter files that were flagged for upload, but not yet uploaded t44u 2013 15
  16. 16. Transfer Improvements • Single Step Process • Transfer “Listens” during publish for any changed (added, modified, deleted) files • It copies these changed files into a separate area • This is what we call a changeset • Changesets remove Publish/Transfer synchronization issues t44u 2013 16
  17. 17. Transfer (Dis)Improvements • Changesets • Only deleted when transfer completed (including deletion of “old” files) • This can result in excessive disk space being used t44u 2013 17
  18. 18. Transfer Improvements • Changesets • Disk space usage will be improved in 7.4.0004 • Wayne “is on the case” t44u 2013 18
