Hi there, is there a way with the pull syntax to tell the datalog engine to get back only one result?
Some Eql is supported on properties/joins and I was wondering if that could be applied to the "root" result as well
I know I can do a ffirst but I guess having in the query would make it easier to read
Hey! For the root, you mean like DataScript's :find ?e . ? Crux doesn't support that currently (it's just sugar), so you will have to stick with ffirst
There was a discussion recently about cardinalities in the pull joins that is probably of interest https://github.com/juxt/crux/issues/1544 - but Crux's pull only helps with the reverse lookup case
We did consider something here recently https://github.com/juxt/crux/issues/1449 - but it's unlikely to become a priority any time soon. PRs are welcome though, of course :)
yeah I think Datascript feature is what I had in mind
