The link posted above, https://docs.xtdb.com/static/learn-xtql-today-with-clojure.html Is that XTQL v1 or v2 ?
That's correct, SQL over the Postgres endpoint is the stable API - the XTQL API is much more subject to ongoing change/feedback (pre-GA). We technically still support XTQL as JSON over HTTP, but have decided to not purse any XTQL multi-lang client strategy for the time being
It's v2. It has tables in the examples.
But at this point, XTQL is Clojure-only (and I think it may get subsumed into the SQL API at some point...?).
