Immutable database and Datalog query engine for Clojure, ClojureScript and JS
Here: https://github.com/tonsky/datascript/blob/6de343b1b3aecb95c21fbe46384face3f99b989b/src/datascript/impl/entity.cljc#L156 This breaks reactive programming semantics where, when `db` updates, `(d/entity db x)` updates but the result is `=` to the prior result and therefore continuous time reactive engines...
### Just an idea As someone pointed out (#130), a **faster** Datascript implementation is needed for applications with a lot of entities. Moreover, it would be great to have a...
Idents?
I'm so excited that you added lookup refs and upsert support! Trying them out right now. I noticed in the changelog you also added entid support - so does that...
With this query: ``` (q '[:find (count ?e) . :with ?i :where [?e :r ?e ?i]] [[1 :r 1 10] [2 :r 1 11]]) ``` I get `1` with Datomic...
The only use-case where this is needed and using a plain vector is not enough is resolving tempids: ``` {:db/valueType :db.type/tuple :db/tupleType :db.type/ref} ``` See also #364 and https://docs.datomic.com/on-prem/schema/schema.html#homogeneous-tuples
In datomic there is a way to combine data as ``` {:db/ident :x/y :db/valueType :db.type/tuple :db/tupleTypes [:db.type/ref :db.type/string], :db/cardinality :db.cardinality/one}` (or many). ``` I understand the `types` are more friendly...
In Datomic: ``` (q '[:where [(ground {}) ?m] [(assoc ?m :x 5) ?m2] :find ?m2 .]) ``` returns `{:x 5}`. But it fails in datascript with `clojure.lang.ExceptionInfo: Unknown function 'assoc...
Attempting an upsert to an entity using its unique tuple attribute does not work as expected. Hope this example is clear: ```clojure (let [conn (d/create-conn {:player {:db/unique :db.unique/identity} :home {:db/valueType...
_This is a backwards compatible change that would vastly improve DX in my opinion_ I've always wondered: **why are entities not transactable?** I find myself converting entities to maps all...
