Peer library

• A Datomic transactor performs ACID transactions for a set of databases
• Server URI
• E.g.,datomic:dev://localhost:4334/

# config/dev-transactor-template.properties
protocol=dev
host=localhost
port=4334
license-key=from_your_my.datomic_registered_account

# run transactor (always run with java 8!)
JAVA_HOME=/usr/lib/jvm/java-8-openjdk ./bin/transactor "config/dev-transactor-template.properties"

(defproject app "0.1.0"
  :repositories {"my.datomic.com" {:url "https://my.datomic.com/repo"
                                   :username [:env/my_datomic_username] ; export MY_DATOMIC_USERNAME= "[email protected]"
                                   :password [:env/my_datomic_password] ; export MY_DATOMIC_PASSWORD= "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
                                   #_#_:creds :gpg}} ; ~/.lein/credentials.clj.gpg (optional)
  :dependencies [[org.clojure/clojure "1.10.3"]
                 [com.datomic/datomic-pro "1.0.6362"]]) ; peer mode

(defproject app "0.1.0"
  :dependencies [[org.clojure/clojure "1.10.3"]
                 [com.datomic/datomic-free "1.0.6362"]]) ; peer mode (free version)
