Hi Victor,
After discussing this with colleagues I'm still unable to tell you why
recentchanges isn't sending out property changes. It definitely should, as
you can clearly observe on production. Please verify if you're not using
some filters on rcnamespace.
Another issue is that even if you get it to work, properties may not be
added properly to the triplestore, because the updater also filters out
namespaces - by default 0 (Q-items) and 120(properties) are processed.
Since wikibase uses different ones (120 and 122), you'd need to use
runUpdate parameter *--entityNamespaces 120,122* (or other values you
might've set up).
Sorry I can't be more helpful - wikibase isn't my area of expertise.

Hi Victor,
Your intuition on "recentchanges" is correct - if Kafka broker is not
specified in options, recentchanges is used and if triples for property do
not appear there, data on it will not be updated.
On the question of whether properties data should appear there, I have to
get back to you on that later - unless someone with more knowledge on
Wikibase manages to answer sooner.
Regards,
Zbyszko

Dear colleagues,
I'm running a custom instance of Wikibase with SPARQL service and I'd
noticed that updater service (runUpdate.sh) doesn't really update
triplestore with new properties created in my Wikibase instance. As well
as I can see, newly created P-item names aren't even returned by API call
for "recentchanges". So new properties with their names and
other attributes never appear in the triplestore after their creation.
Once the property is used in some statement or qualifier, corresponding
triples are put into the triplestore immediately, but the property remains
without names or descriptions.
Is it because properties are managed centrally in Wikidata? Is it assumed
that I should reload a full snapshot each time I create a new property? Or
is it some bug on my side?
Thank you for your help!
Victor Agroskin
