Hi,
There is a number of services running on our wikis, such as english wikipedia which are for example generating some information and frequently update certain page with these data, (statistics etc). That makes tons of revisions that will be never needed in future and which will be in database with no option to remove them.
For this reason it would be nice to have an option to create a special page on wiki which would have only 1 revision and its data were overwritten, so that it wouldn't eat any space in DB. I know it doesn't look like a big issue, but there is a number of such pages, and bots that update them generate lot of megabytes every month. Bot operators could use for example external web server to display these data, but these can't be transcluded using templates, like here: http://en.wikipedia.org/wiki/Wikipedia:WikiProject_Articles_for_creation/Sub...
What do you think about this feature? Is it worth of working on, or this isn't a big issue? Keep in mind that even if we have a lot of storage, these unneeded data make the dumps larger and processes that are parsing the XML files are slower
