If adding a LIMIT makes the query work, we can just edit the example to have the said limit. It is only an example query, it doesn't have to return all the results.

Thanks all for the explanations, now my point is on the examples as seen by some first Wikidata users: if the examples are there and fail, that's disappointing.

Have we to comment out examples that could fail ? Should we mark this ?

I don't like the latter, but if it is a contingent situation it makes sense.

 

Till the work load is not managed, e.g. by optimizations, can we increase the timeout ?

 

Thanks

imho: We can use subquery for optimization so the label service doesn’t have to do as much work

https://w.wiki/9zD ( LIMIT 1000 + Labels + Descriptions )

LIMIT 10000   -  6924 results in  59861 ms  (  birthday = 13 October 2014 ) 

LIMIT 1000   -    1000 results in  12050 ms

 

the ideal case will be - if the sparql engine can detect and automatically optimize this type of queries.

Hi,

 

The "wikibase:label" service is know to consume and it timeouts often (nothing new it happens since the beginning ; but as Wikidata grows, it's more or more visible).

 

This simplified version of the query works (without intermediate variables and without the service): https://w.wiki/9yR

 

Cheers,

I noticed few timeouts on example queries, for example

 

Whose birthday is today ?

 

Is it correct to have this condition ?
