Best plan so far: create code in wikibase/term-store to clean up dead records and make it invokable from outside the library. Then create some maintenance script in Wikibase that invokes this code. ---- Old investigation stuff: Because of the normalization we are ending up with unused records in the DB. When the terms of a property are deleted, the records in property_terms are dropped. Referenced records in terms_in_lang are not dropped, etc. How do we want to deal with these unused records? 1 Leave them be, no need to clean them up ** Con: wasted space in db (do we care?) 2 Have a maintenance script that periodically cleans them up ** Con: extra dev work ** Con: need to run extra script 3 Clean them up immediately ** Con: extra dev work ** Con: Write performance penalty 4 Clean them up post request with a job ** Con: most extra dev work ** Con: Write performance penalty (perhaps less severe then 3) 5 ???

When terms are either updated or deleted in a terms store, respective records of deleted or old values in the database must be inspected for orphanism and cleaned up accordingly. ---- Old investigation stuff: Best plan so far: create code in wikibase/term-store to clean up dead records and make it invokable from outside the library.
