12. Preview & Publish Improvements
• This was only the case with certain Navigation
Objects (Keyword Search Content, Top

the publish engine

• Transfer was a two-step process
• Generate / check file hashes
• Upload modified files

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

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

17. Transfer (Dis)Improvements
• Changesets
• Only deleted when transfer completed
(including deletion of “old” files)
• This can result in excessive disk space being
used

18. Transfer Improvements
• Changesets
• Disk space usage will be improved in 7.4.0004
• Wayne “is on the case”
