Dear SPARQL team,
in SQID, I now frequently see WDQS responses of type 429 when trying to load a page (doing this will usually issue a few dozen queries for larger pages). How many SPARQL queries are users allowed to ask in a certain time and how should tools behave when they hit this limit?
Best regards,
Markus

Right now, we have a limit of 5 parallel requests from the same IP. If the requests are one after another, there should be no limitation. So I would make sure the code does not make too much requests in parallel, at the same time.

Ok, thanks, we should be able to implement this with some synchronisation.
