Embedded (pure Java) database for Clojure

I'm in need for an embedded database for a Clojure application. Maybe it's the same criteria as for any other Java application but I rather get some other people's opinion anyway. I'm not picking SQLite because that's not pure Java so distribution of a standalone application gets much more complex. It seems the way to go is Apache Derby. Anything else I should consider?

Solution

  • Without a doubt, H2

    Here are the settings, 

     (def demo-settings
   {
    :classname   "org.h2.Driver"
    :subprotocol "h2:file"
    :subname     (str (System/getProperty "user.dir") "/" "demo")
    :user        "sa"
    :password    ""
   }
  )

    And then the usual Clojure SQL code: 

      (with-connection demo-settings 
    (create-table :DEMO_TABLE
           [:M_LABEL "varchar(120)"]
           [:M_DATE "varchar(120)"]
           [:M_COMMENT "varchar(32)"]))
