Dynamic Converter Administration Guide
If you or your users make metadata-only changes to a content item, neither a new file nor
a new time stamp is created—and the changes will go undetected. To address this
problem, you must make sure that all metadata changes are identified by Dynamic
Converter. You can do this by enabling the “Reconvert when metadata is updated” option
on the Dynamic Converter Configuration page (see page 2-9). This option forces the
content server to update the time stamp of the source content items after a metadata
update. With this option enabled, the time stamps of all web-viewable formats are updated
to reflect the metadata change that occurred for the corresponding source content item.
The updated time stamp, as a result, will be recognized by Dynamic Converter, and the
content item—with metadata updates—will be reconverted.
Database Method of Checking
You can choose to use the database method of checking whether the content item’s
metadata has been updated. You set this option on the Dynamic Converter Configuration
page (see page 2-9). With this configuration option enabled, content item updates continue
to signal timestamp changes in the converted files, but the new caching and querying
method is not used to determine if the content items are up to date. Instead, the content
server database is queried for this information. You might use this method, for example, if
you are experiencing problems with the optimized query feature or you are
troubleshooting a related issue.
Timestamp Checking Frequency
By default, Dynamic Converter checks the time stamp of the converted content items
every 1,500 milliseconds, or 1.5 seconds. You can increase or decrease this value if you
would like to balance the number of queries performed with the number of visitors to your
site. You can change the timestamp checking frequency on the Dynamic Converter
Configuration page (see page 2-9).
If you increased this setting to, say, one minute (60,000 milliseconds) and a new content
item is checked into the content server, then the new version of the content item will not be
available to users until one minute has passed.
