Ok, so I finally read Tpt's rundown of Blazegraph
alternatives, and
it's great. Thank you!

o Is there something better than Blazegraph for Wikidata?
<https://thomas.pellissier-tanon.fr/blog/2023-01-15-wdqs.html>
What's the latest on benchmarking alternatives and future migration?
- WDBench seems actively maintained
<https://github.com/MillenniumDB/WDBench>; any narrative update since
last year's paper? Is something else used internally?
- The WDQS backend updates
<https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/WDQS_backend_update>
last year were informative. Are there updated risk projections +
timelines?

All,
For the record, the following is inaccurate:
Virtuoso is a SPARQL implementation developed for more than a decade by
a small company, OpenLink Software. It is at its core a SQL database
targeting OLAP workloads with a layer on top converting SPARQL to SQL.
It seems to provide great performances, powering very large endpoints
like Uniprot. *However, according to WDQS Backend Alternative work,
Virtuoso is also tuned for bulk-load with high-frequency read, and not
for read/write.* But, this is also the case with Blazegraph. So, it
might be interesting to do a good benchmark to see if it actually
outperforms Blazegraph or not.
Virtuoso is a high-performance and scalable multi-model DBMS with a very
strong OLTP pedigree -- FWIW .
We will soon be releasing pre-loaded and pre-configured Wikidata
instance editions for both the AWS and Azure clouds that anyone can test
for themselves.
