问题
Is there a limit for queries on Wikidata (SPARQL queries only, not editing)? I couldn't find any official documentation about this. I wonder how strong queries are limited per minute/hour (and per IP-address).
回答1:
Yes, there are limits.
Single query is currently limited to 1 minute runtime. Docs are here: https://www.mediawiki.org/wiki/Wikidata_query_service/User_Manual
Also, each IP is limited to 5 concurrent requests currently. There's no limit on how many sequential requests can be processed.
These limits may be adjusted depending on capacity and traffic.
