Is it not possible within xtdb to query for attributes themselves?

(xt/q (xt/db xtdb-node)
        '{:find [?p]
          :where [[?s ?p ?o]]})

Ahh I see there is this issue: https://github.com/xtdb/xtdb/issues/1024

you can get attribute-stats that will give you the available attributes fwiw

Ok that’s good to know, but that’s database wide right? You can’t query for what attributes are available given other query constraints
