IMO, the Knowledgbase entry for the virtual columns http://kb.askmonty.org/v/virtual-columns is among the best and most useful entries we have. It describes the feature, suggests use cases and demonstrates functionality in a straightforward manner. I'd like to see equal care taken to provide the same information for all user-facing features implemented in MariaDB. If developers can devote a little time to ensuring such documentation is started, the community (myself included) will be happy to expand the articles to usable states. Just ask on -discuss or IRC. I think KB articles can be started in the feature planning phase, and updated as the feature is implemented. I imagine the KB acting as an ongoing feature implementation and use log is more likely to maintain quality developer input than is asking an entire document be written from scratch after the feature is merged.
