During the construction process of SPARQL, I am having following error. I don't understand whether there is limitation on querying or not?
Response:
Virtuoso 42000 Error The estimated execution time 253 (sec) exceeds the limit of 240 (sec).
This means the data you are getting out takes longer than usual to be processed. If you are using the online endpoint, you can't do anything but setting a limit or filtering (filter) your data even more. Or you can consider getting a dataset dump and run in on your system.
