Are there publicly available LDBC SNB Interactive Worklad queries in Cypher or SPARQL?
Hi,
in the The LDBC Social Network Benchmark: Interactive Workload paper from 2015, it is said that The base definition of the queries is in English, from the LDBC website[4](ldbcouncil.org/developer/snb) one can find query definitions in SPARQL, Cypher and SQL, as well as API reference implementations for neo4j and Sparksee. Did this claim become obsolete, ie. did the mentioned queries disappear from that website in the meantime?
From what I understood until now it was up to the reader to write down queries for the graph databases that they targeted. Were there any efforts on the LDBC side or by the community to maintain queries expressed in popular graph query languages like Cypher or SPARQL? I assume it would involve reasonable effort as the SNB dataset schema evolves and eg there are new features being added to Cypher Query Language.
Best regards, Jakub

LAGraph_cc_fastsv defined in header but not .so-file
This is expected. All of those functions will be revised, and experimental ones get dropped as we go. The LAGraph.h is a very rough draft. The updated API is in LAGraph2.h, likely not in any docker image yet.

LAGraph_cc_fastsv defined in header but not .so-file
In the header file I see:
$ cat LAGraph.h | grep fastsv
GrB_Info LAGraph_cc_fastsv (
GrB_Info LAGraph_cc_fastsv2 (
GrB_Info LAGraph_cc_fastsv3 (
GrB_Info LAGraph_cc_fastsv4 (
GrB_Info LAGraph_cc_fastsv5 (
GrB_Info LAGraph_cc_fastsv5a (
GrB_Info LAGraph_cc_fastsv5b (
But in the shared library only the last of these symbols are available:
$ nm -D liblagraph.so | grep fastsv

Evaluate performance of Differential Datalog & Materialize
When you visit this benchmark again, I think it would be interesting to add Differential Datalog and Materialize to the list of tools you evaluate. They are new incremental query engines which seem to gain noticeable traction.
