What does it do?¶
This extension produces an array with information which part of tt_news cached views has become not up to date after latest tt_news record update/create/delete operation.
The array is then used by other extensions (through hook) to clear proper cache records.
Hook mechanism allows to use the array information by many extensions. So one extension can delete cache_pages, other can remove statically generated files if extensions like for example nc_staticfilecache are used.
Why should I use it?¶
Cache mechanism for extension in TYPO3 is not perfect so far. If you have lot of news (thousands) then typically with each news add/update/delete you clear all your cached news pages. This extension allows to clear only those cache of tt_news extension which is needed.
What you gain is:
Almost all news are always cached so it means faster access for you news section.
Less server overload so it means faster page generation at all. The server is not overloaded by unnecessary tt_news views regeneration. This extension can save hours of unnecessary server work. (count yourself: few thousands news x each generates 200ms)
