I had been using mwlib to interface with Wikipedia dumps for a research project. The first step I did was to run:
mw-buildcdb --input enwiki-latest-pages-articles.2012.03.26.xml.bz2 --output 2012.03.26.no-redirects --ignore-redirects
My wikiconf.txt in that output directory sets the type to nucdb. In my Python code that operates on the dump, I call mwlib.wiki.makewiki on that conf file.
I saw in the commit log on GitHub that CDB support was going away. What is the current correct method for loading a Wikipedia dump file?
