Hi Caty,
Thanks but I think we should focus on the databases that our users use for XWiki. We have that info already with the active installs.
https://www.xwiki.org/xwiki/bin/view/ActiveInstalls/ k, I understand, with the note that those graphs are influenced by what we support. In the case of Active Install, would be nice to display also the DB versions.
Yes. However we can’t support all versions and people usually lag behind. So I don’t think we should support more than the latest one. Already hard to do.
BTW we do have the versions, we just don’t display them. See http://activeinstalls.xwiki.org/#/dashboard
I did a quick pie chart for mysql: https://www.evernote.com/l/AHe-MYCE-09Nuoyau9jFQf45OgtIZKmaqk0
What’s interesting is that version 8 is not used yet. So we could keep staying on 5.x for now probably.
XWiki does not start at all on MySQL 8 so not sure it's a good criteria :)
Good point :) Thanks -Vincent
Thanks -Vincent
Thanks -Vincent
Thanks, Caty
It’s already a lot of work :)
My goal with this thread was not fully review the list of supported databses, just to make it more clear the versions of them we want to support.
Thanks -Vincent
