Hi, I’m looking to be able to synchronize cloud to dev-prem. How can I do this? Has anyone done it before?

I am curious about installing a transaction function on my in memory test database. I think this is same proceedure as on-prem documentation which says to install like this

;; tx-data to install the function
[{:db/ident :add-doc
  :db/fn #db/fn {:lang "clojure"
                 :params [db e doc]
                 :code [[:db/add e :db/doc doc]]}

but i already have the code setup in a function somewhere like my.package/my-function

so i am curious how to install it ..

i am trying things like

(d/transact conn {:tx-data [{:db/ident :my-function
                                 :db/fn    `my.package/my-function}]})

but that not making datomic very happy ( says `my.package/my-function is not a valid :datomic/fn for attribute :db/fn )

also the example does not even work in the in-memory db I get error

Syntax error compiling fn* at (middleware_test.clj:13:1).
Can't embed object in code, maybe print-dup not defined: clojure.lang.Delay@3151d7b9

when i do this

(d/transact conn
      {:tx-data [{:db/ident :add-doc
                  :db/fn    #db/fn {:lang   "clojure"
                                    :params [db e doc]
                                    :code   [[:db/add e :db/doc doc]]}}]})

Trying out datomic cloud for the first time and noticed that there’s not a connection shutdown function the same way there is in the on-prem version of datomic. I assume then that there’s no cleanup that needs to be done when I’m ready to shut down my client/system?

hi all

Back for another go at Datomic 🙂

In the tutorial it says:

(def items-by-type-ionized
  "Ionization of items-by-type for use with AWS API Gateway lambda
proxy integration."
  (apigw/ionize items-by-type))
