Hello all,
This email is important for you if you are running an instance of Wikibase.
As part of deprecating wb_terms table[1] for the whole Wikibase codebase,
the new term store is now wired to the Wikibase default setup and per the
default it's going to read from the new term store.
It means that next time you update your Wikibase (to master or 1.35 once
it’s out), you should run update.php [2] so it creates the new tables and
migrate your data to the new term store. This might take some time if you
have a large installation. If you’re not running the script, you might see
errors appear.
The default value until the next mediawiki major release (1.35) is going to
stay "read new, write both", meaning you will have both old and new data
side by side but it reads from the new one. By the next major release after
1.35, we are going to fully drop wb_terms table from Wikibase.
Please note that there’s an exception related to search: if you are not
using ElasticSearch, the search still uses the old term store (wb_terms
table). That’s why the default is to write to both term stores for now
until the search works for the new term store properly.
If you have any questions or issues, feel free to write me.
Cheers, Léa
