Hi! When serializing a DataScript conn with pr-str I see that all :datoms tuples have a fourth value 536870913 e.g. [3 :tag/name \"Clojure\" 536870913] Since DataScript doesn't maintain a transaction log, is this just a placeholder value that has no use whatsoever?

It's still queryable, and you can maintain your own transaction log.

I'm sure it has more utility, but can't think atm

@danielstockton thanks!

I have another question regarding serialization: When I pr-str an empty db it gives me a nice format:

(pr-str (d/empty-db)) 
; => "#datascript/DB {:schema {} :datoms[]}"

(pr-str conn)
; => "#object[cljs.core.Atom {:val #datascript/DB {:schema {...} :datoms [...]}}"

(pr-str @conn)

The conn is just an atom holding the db value

ahh that makes sense 🙂

yea that works just fine now, thanks again @danielstockton

I was actually wondering yesterday, since it maintains the txid, how hard it would be to create an as-of function if you maintained timestamps of transactions

I assume someone must have done this before?

hey, just discovered datascript.. do people consider it a viable open source alternative to datomic?

It lacks persistence. Datahike is aiming to be more in that space.

Or, rather, lacks durability.

Hi! Is there a version of the . operator to :find that will blow up if more than one result was found instead of silently discarding every result but the first?
