Pulquero added a comment to T289621: Evaluate Halyard as alternative to Blazegraph.

That is a shame, I've been making improvements to really give the other stores a run for their money. Well, for reference, the results so far are that in a single-box configuration, the current dump requires <1.5TB of disk space loaded. And a preliminary test of the difficult query below without full optimisations enabled, was taking around ~minutes to execute (I'm in the process of testing it properly).

For clarity, RDF-star.

  1. No.
  2. I'm happy to try to work with someone here to make that happen. I've already been in discussions with @nguyenm9.
  3. You need at least a single HBase node. It can all be run on a single machine. What is the spec of the current machine you are using?

Hi, I would like to suggest my Halyard fork, Halyard* (supports RDF*), https://github.com/pulquero/Halyard, for consideration. It contains numerous non-trivial changes beyond the original to handle high-volume transactional type queries. And more crucially, it contains fixes to pass some previously skipped sparql test suite cases.
