Service via post

Support Feature Request

Hi all, we notice that the service clause in stardog execute a GET request in the target endpoint.

The problem with GET request is that long queries cannot be processed.

Is it possible to execute it as a POST request?

Best,

Hi, how are you submitting this query? HTTP, CLI, Webconsole, or some other method? Our /db/query endpoint does accept POST requests for explicitly this reason.

3

The query is submitted by stardog itself, as It is part of a clause service
into another sparql query.

Aparently stardog fires a get request for any service clause. I wonder if
it could be a post request instead.

4

Hi Samur, I have found where this is happening and I’ve opened up an internal ticket to address it. Look for a fix in an upcoming release. Thanks for the report!

5

Dear Sephen, could you please inform me, on which release was the issue above fixed?

6

You can always keep an eye out for resolved issues in the release notes.

7

I already check it. It is not there. I need to know the first release where the issue was fixed.
