Issue:Caching

Problem

Would like a way to Cache Pages. I was thinking a Bot that runs the DPL query and would write the static result to the Actual Article. Then you could schedule the bot to refresh the Pages as often as necessary.

I am adding this as a Feature request. I am not smart enough to write the bot.

Yes. This would be a really useful enhancement and I have thought about this several times. But I never found time to develop that feature. The point is, however, that your article might look quite ugly if the output of a DPL query were contained as wiki text. The best thing would be to have the expanded DPL query(queries) for an article in a page with identical name but in a separate namespace. Then DPL could look for that page, check its date (maybe even update it ad-hoc if it were expired) and include the result, possibly with a small note that the content was taken from a cache.

I would be willing to support someone with ideas and advicer on the DPL source code if you could find someone to do the programming.

I am especially excited about this as it might make it possible to use DPL on really large sites like wikipedia...

Hmm..I think something like this already works (but with the downside of DPL query output showing in wiki text):

Suppose you want ArticleA to show cached results of {{#dpl:category=baz|someparam={{sometemplate}}}}.

Create Template:QueryA with this content: {{subst<includeonly></includeonly>:#dpl:category=baz|someparam={{subst<includeonly></includeonly>:sometemplate}}}}.

Whenever you want to update, write {{subst:QueryA}} into ArticleA.
