[Wikidata-bugs] [Maniphest] [Updated] T148504: Query repeatedly gives "Unknown error"
Nikki added a comment. That property has only been used about 4000 times, I didn't expect that to translate into ridiculous amounts of data. I don't want or need ten million entries, this isn't even the query I actually wanted results from. What I was trying to do was get statements with no references for a couple of thousand items. It sounded like it would be pretty straightforward, select some items, select their statements, filter out any with a reference... but apparently not, since my queries kept timing out. I simplified the query and simplified it some more, tried different properties, etc, trying to work out what was causing it to time out. Then suddenly I got to this query and it just said "Unknown error". Up until that point, the queries (excluding the more complicated ones which were timing out) had been returning results within a few seconds and my browser had been having no problems displaying the results so it didn't seem problematic. I don't see any indication of how large (in kB/MB) a particular response is. If you want people to avoid queries which return a large amount of data, it would help to actually show how big the response is and whether it's considered excessive. If someone does accidentally produce a query which returns too much data, it would better (and more effective) to show an error message saying it produced too much data rather than "Unknown error". As for what I was originally trying to do, this isn't my original query, but it's a simple demonstration of the problem I was having: This query returns results in a few seconds but returns lots of stuff I don't want. This query returns results in a fraction of a second. Put them together like this and it times out. As I wrote in T116298 about a completely different query which behaves in the same way, this makes no sense to me. (WikidataFacts did manage to come up with a version of that query which works - here - but why that works while the original times out is a mystery to me)TASK DETAILhttps://phabricator.wikimedia.org/T148504EMAIL PREFERENCEShttps://phabricator.wikimedia.org/settings/panel/emailpreferences/To: NikkiCc: Smalyshev, gerritbot, Jonas, Nikki, Aklapper, mschwarzer, Avner, Lewizho99, Maathavan, debt, Gehel, D3r1ck01, FloNight, Xmlizer, Izno, jkroll, Wikidata-bugs, Jdouglas, aude, Deskana, Manybubbles, Mbch331___ Wikidata-bugs mailing list Wikidata-bugs@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikidata-bugs
