@rvesse once created #1655 which makes GRAPH ?g { } return the set of distinct graph names from the TDB2 index.
So far this work was not leveraged for arbitrary single tuple patterns, such as:
SELECT DISTINCT ?p { ?s ?p ?o }SELECT ?g (COUNT(DISTINCT ?p) AS ?c) { GRAPH ?g { ?s ?p ?o } } GROUP BY ?g...
The proposal is to extend OpExecutorTDB2 to make OpDistinct and OpGroup leverage indexes
Are you interested in contributing a solution yourself?
Yes
