Immutable database and Datalog query engine for Clojure, ClojureScript and JS
I'm currently optimizing the startup time of datascript and one more slow part (besided my PR for `rschema`) is the --in production unnecessary-- schema valdation. Could this be wrapped in...
[(chain ?a ?attr1 ?attr2 ?b) [?a ?attr1 ?i0 ?i0 ?attr2 ?b]] I have a query that can use this rule 4 times but for which I currently manually expands every...
The following transaction fails in Datomic, but not DataScript: ``` [[:db/add (d/tempid :db.part/user -1) :some.ref/attr (d/tempid :db.part/user -2)]] ``` This means a little bit of extra work automatically syncing Datomic...
It would be nice to mirror more closely here.
In Datomic, if you pull `:db/id` for any eid `x` that doesn't exist, you get `{:db/id x}`. In DataScript, you get `nil`. Further, `(pull-many [:some/attr] missing-eids)` evaluates to `[]` in...
In deeply nested maps, datascript can successfully build relationships with both the lookup ref, and reverse lookup ref, however, it seems like when you combine them, it does not create...
Such a protocol would make it possible to build custom connection/ref objects with special lifecycle functionality and capabilities. Right now the connections is just an atom, but it would be...
There is seems no way to obtain a schema from db object via javascript API. Could it be extended?
With datascript 0.15.2 in Clojure ``` (require '[datascript.core :as d]) (let [conn (d/create-conn {})] (d/transact! conn [{:db/id -1 :name "Maksim" :age 45 :sym 'foo}]) (d/q '[:find ?n ?a :where [?e...
`datascript.db/ref?` and `datascript.db/multival?` are useful in application code but the changelog describes datascript.db as internal. Would you consider making those functions a part of the public api?
