Re: [Wikitech-l] changes coming to large dumps

[Derk-Jan Hartman]

It seems that the pagecounts-ez sets disappeared from
dumps.wikimedia.org starting this date. Is that a coincidence ?
Is it https://phabricator.wikimedia.org/T189283 perhaps ?

Here it comes:

For the April 1st run and all following runs, the Wikidata dumps of
pages-meta-current.bz2 will be produced only as separate downloadable
files, no recombined single file will be produced.

No other dump jobs will be impacted.

A reminder that each of the single downloadable pieces has the siteinfo
header and the mediawiki footer so they may all be processed separately by
whatever tools you use to grab data out of the combined file. If your
workflow supports it, they may even be processed in parallel.

I am still looking into what the best approach is for the pags-articles
dumps.

Please forward wherever you deem appropriate. For further updates, don't

A reprieve!  Code's not ready and I need to do some timing tests, so the
March 20th run will do the standard recombining.

For updates, don't forget to check the Phab ticket!

We'll probably start at 20GB, which means that WIkidata will be the only
wiki affected for now.

Could you please translate "too large" to megabytes?
