Timeout when validating resources with large number of arcs

[labra]

The following attempt of validation (a Shanghai hospital) agains the entity schema of hospitals:

curl -i -X POST -H "Content-type:multipart/form-data" 'http://localhost:8080/api/wikidata/validate' \
                                                         --form-string 'item=<http://www.wikidata.org/entity/Q33121756>' \
                                                         --form-string 'entitySchema=E187'

gives a timeout because the entity schema E187 refers to country and the country is Chile (Q148) which seems to take more time than expected to be retrieved and the whole result is a timeout.

Check how we can improve this situation by increasing the time the server waits or using some kind of streaming retrieval.

Looking at logs, there is a warning:

requestTimeout (5 minutes) is >= idleTimeout (1 minute). It is recommended to configure responseHeaderTimeout < requestTimeout < idleTimeout or disable some of them explicitly by setting them to Duration.Inf.
