hi,
about the group_concat function I found many posts where we
talk about the following parameters:
* ROW_LIMIT
* PRE
*
SUFFIX
for instance:
group_concat (? chapterTitle; separator = " "; pre
= " "; suffix = " ")
Are they also available in fuseki?
thanks

Hi,
I load triples in RDF Thrift format generated using Jena's
StreamRDF2Thrift class.
Loading the same triples with the ttl format I
have no problems.

Hi,
you are right, I was not clear in the request. I try to

I have a knowledge base of over a billion
triples.

the future I will have many queries that will return a lot of data)

Hi,
i am using a fuseki server and need to run a query which returns
a lot of results. The use of the HTTP call (http: // localhost: 3030 /
ds / query = myQuery) is very slow and inefficient. I thought about
using the tdbquery command. But I don't want to stop fuseki. Is there
any way to do this
Hi,
I would like to upgrade to the OpenJdk version of Java.
I
have always used the Oracle Java one on older versions of Jena.
For Jena
4.3.1 there may be contraindications to using OpenJdk or AdoptOpenJDK?

Thanks for the reply.
The data model is relatively simple, dealing
with transactions of goods and user data.
I will wait for the next
release of Jena.
When is it scheduled?

I have to use limit and offset on a sparql query run on Jena
Fuseki to get paginated results.
But reading the w3c documentation I
