Hello!
While working on my improvements to MediaWiki Import&Export, I've
discovered a feature that is totally new for me: 2-phase backup dump.
I.e. the first pass dumper creates XML file without page texts, and the
second pass dumper adds page texts.
I have several questions about it - what it is intended for? Is it a
sort of optimisation for large databases and why such method of
optimisation was chosen?
Also, does anyone use it? (does Wikimedia use it?)
