There is also no need to log that an edit, which is marked as autopatrolled
in the edit table, has been patrolled.
For edits, which are not autopatrolled, it makes sense to log by whom and
when it was patrolled, but for an autopatrolled edit that is kinda useless.
Getting rid of this would already eliminate the vast majority of log
entries.

Please pardon the non-tech person, as I may be asking a question with
obvious answers, but what, exactly, is the
problem here? Storage space is
cheap and logs are text, which takes up very little space...
I suppose it's related to what below.

Oggetto: [Xmldatadumps-l] wikidatawiki -- toooo many edits

Hello dumps users and developers,
You may have noticed that the wikidata pages-logging xml dump step has
taken days for the last couple of runs. In fact for the most recent
run, it did not complete properly, as the database handling the query
was upgraded in the middle to mariadb.
So the short version is, if you are using that file, go get a new copy:
http://dumps.wikimedia.org/**wikidatawiki/20130417/**
wikidatawiki-20130417-pages-**logging.xml.gz<http://dumps.wikimedia.org/…
If I don't have a patch in by next run, I have a workaround I will run
by hand that takes 2 hours or less, as opposed to 4 days.
The long version is that the pages-logging file is already about half
the size of en wp's table, and that the number of edits per minute is
much larger, see:
https://wikipulse.herokuapp.**com/ <https://wikipulse.herokuapp.com/>
There's a lot of deletion and a lot of churn too due to the dispatch
mechanism.
Also, they apparently have RCPatrol enabled and a pile of bots, which
means that the log consists of 99% entries 'bot X editing Y marked it as
autopatrolled'.
These things in combo turn out to be the perfect storm for my simple
select query, causing it to start at normal speed and then get ever
slower. I suppose in another couple months it would take so long to run
it would never finish...
Ariel
