Copy Wikidata dumps to HDFs
Open, LowPublic

Description

Now that T202489: Copy monthly XML files from public-dumps to HDFS is done, we'd love to see Wikidata dumps in HDFS. We already have one-off dumps in /user/joal/wmf/data/wmf/mediawiki/wikidata_parquet/20180108. This task is about creating dumps periodically in an automated way.

One immediate use case is generating recommendations for article creation. We already have recommendations that are based on the above indicated dumps. But before going to production, we'd like to generate a new set of recommendations.

Event Timeline

Not sure when we'll be able to do that. However there is more recent dump available: /user/joal/wmf/data/wmf/mediawiki/wikidata_parquet/20181001 :)

Thanks, @JAllemandou! The more recent dumps are very useful.

@Nuria we should fit this in somewhere! Maybe a Q3 goal? :D

Having missed most of goals this quarter due to our mw woes i think this might need to be moved to next quarter (q4?)

@Nuria can your team help us with this task during Q4? Content Translation (currently the biggest user of the translation recommendation API) is aiming to go to production (in at least one language) in Q4: T102107 . We want to make sure the service is productionized by the time they move to production.

Most of the complicated things already exist for this to work (equicalent of rsync for HDFS, spark job converting wikidata json dumps to parquet).
I wanted for T216160 to be settled before moving into productionization (having the same date for the various dumps we handle simplifies quite a bit), and it takes time.

@JAllemandou, do you think this is now unblocked?

@abian : this is still not happening on a recurrent schedule yet.
