Is there a way to restore into dev-local a backup taken from datomic-free?

Good evening everyone!! Is there a way to manipulate arrays with Datomic? (unfortunately I can’t use tuples, as they’re limited to 8 scalars).

I think that limit only applies to heterogenous tuples?

https://docs.datomic.com/on-prem/schema.html#homogeneous-tuples vs https://docs.datomic.com/on-prem/schema.html#heterogeneous-tuples

Well I thought so too, but apparently I am unable to transact tuples larger than 8 values using :db.type/tuple :

(d/transact conn [{:db/ident       :weights
                   :db/valueType   :db.type/tuple
                   :db/tupleType   :db.type/double
                   :db/cardinality :db.cardinality/one}])
(d/transact conn [{:weights [0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8]}])
(d/transact conn [{:weights [0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9]}])

https://docs.datomic.com/on-prem/schema.html#tuples says: A tuple is a collection of 2-8 scalar values

that is unfortunate

consider using bytes and Double/doubleToLongBits?

I’ll give this a try thank you!!

or DataOutputStream

(http://java.io class)

Thanks a lot

dev-local can migrated to the peer server correct?

guess it's just a matter pointing the transactor to the data dir
