Bug ID: 45316
Summary: Column pp_propname in table PageProps should have an
index
Product: MediaWiki
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: General/Unknown

Column pp_propname does not have an index. That will block creation of
maintenance pages based upon set page props. Such pages are important for the
overall quality of the made pages, especially the quality of Wikipedia and
Wikidata.
One example is text analysis that sets page props due to the outcome of the
analysis of the whole page. Such text analysis could for example be the
readability of pages. If the readability is limited to a category it is
possible to get the articles for that category and then analyse the page props.
It is although not possible to query for bad readability across the whole wiki.
An other example is marking pages with page props that use a specific parser
function and then list those pages. The parser function could also mark the
pages individually with different page props. The same problem will then arise
as in the previous example.
The existing table is rather large so the load problem on English Wikipedia
should be considered when creating the index.
