Hi Ghislain, I’m afraid there is no good answer yet. Most common way I’ve counted triples myself if by using fn:count(cts:triples()), but according to this thread:
https://lists.marklogic.com/message/j5pxmjjktakhianb ..both approach involve deduping triples, which causes either approach to be slow. Things might have progressed with ML9, so if you haven’t tried that, could be worth giving that a go. The only other option that comes to mind right now is http://docs.marklogic.com/cts:triple-value-statistics. Just run that without args, and it should return a total count. From the looks of it that is a non-deduplicated count, as it is higher than the count of cts:triples, when I tried on a small set of triples locally.

The database configuration has the triple index set to true, and I get can make simple query like `select distinct ?s where {?s ?p ?o} limit 10 ` I wanted to know the exact number of triples using the /qconsole by making a select (count(*) as ?total) where {?s ?p ?o } However this operation never gives me any result. Also how can I get the number of triples from the MLCP tool as it said : `OUTPUT_RECORDS_COMMITTED: 7280660`. Is there a way to compute the number of triples from the notion of "records" in Marklogic? Thanks in advance. Best, Ghislain -- -------------------------------------------- Ghislain A.
