I'm looking for code that I've seen before in I believe the day-of-datomic repos or something similar where Stu Halloway wrote a series of queries showing how to debug a datalog query to see how many entities were being resolved at each step

does have a link to what I'm talking about, I haven't been able to find it

@jaret do you know what I'm talking about?

@adamfrey are you talking about decomposing a query?

https://github.com/Datomic/day-of-datomic/blob/master/tutorial/decomposing_a_query.clj

helps you find the optimal clause ordering with little domain knowledge ^

Hi all, is there a benefit to using datomic.api/attribute over datomic.api/entity?

Hey, modelling question here. Say I've got some images which are "confirmed" at some point, at which time I add a datom [eid :image/confirmed-at (Date.)], so the field is either present or missing for any given image. Now I'm trying to find unconfirmed images. Is there a performance difference between these two clauses? (not [?i :image/confirmed-at]) [(missing? $ ?i :image/confirmed-at)]

@joe.lane I’ve tried various things, but keep getting the same error.

Has anyone gotten an ion push/deploy working on windows?

clojure -A:ion -m datomic.ion.dev '{:op :push}'

{:command-failed "{:op :push}",
 :causes ({:message nil, :class NullPointerException})}

(it has worked before)
