Hello all,
For almost a year, the Wikidata development team has been working on the task of redesigning and migrating the wb_terms table, which had become too big and unsustainable over the years.
You can read the tale of our journey on this blog post: Come to Terms with Changes https://phabricator.wikimedia.org/phame/post/view/195/coming_to_terms_with_change/
If you’re a tool maintainer and your tool queries directly the Labs database replicas, you can read more details https://lists.wikimedia.org/pipermail/wikidata/2020-March/013901.html about the next steps and how to update your code.
Congratulations to all the developers involved in this big project!
Cheers,
