Has someone here used Datomic with Algolia before, or with something similar? If so, are there any gotchas or something I should be aware of?

Re: https://docs.datomic.com/cloud/getting-started/configure-access.html#authorize-user https://docs.datomic.com/cloud/ions/ions-tutorial.html#org6699cd4 Please can you confirm whether or not administrator permissions are required for all applications to connect to datomic cloud?

When initially transacting your schema on a fresh database and using tuple attributes, do folks typically do 2 transactions -- one for the schema without tupleAttrs and one with the tupleAttrs?

Wait, order in the transaction appears to matter! This transaction fails

(d/transact conn {:tx-data [#:db{:ident       ::a+b,
                                   :valueType   :db.type/tuple,
                                   :tupleAttrs  [::a ::b],
                                   :cardinality :db.cardinality/one,
                                   :unique      :db.unique/identity}
                              #:db{:ident       ::a,
                                   :valueType   :db.type/string,
                                   :cardinality :db.cardinality/one}
                              #:db{:ident       ::b,
                                   :valueType   :db.type/string,
                                   :cardinality :db.cardinality/one}]})
