You may discover soon after adding logging to your Ions that CloudWatch really sucks. Fortunately you can forward your logs to Loggly instead. See here.

Say you define a composite tuple like so:

#:db{:ident :foo,
     :valueType :db.type/tuple,
     :unique :db.unique/identity,
     :tupleAttrs [:bar :baz],
     :cardinality :db.cardinality/one}

Now suppose you want to change [:bar :baz] to [:bar :quux]. The [Datomic

#!/usr/bin/planck
(ns deploy.core
  (:require [cljs.reader :refer [read-string]]
            [planck.shell :as shell]))

(defn sh [& args]
  (let [result (apply shell/sh args)]
    (if (= 0 (:exit result))
      (:out result)
      (throw (ex-info (:err result) {})))))

If you call clojure.tools.namespace.repl/refresh before requiring any namespaces referenced in data_readers.clj, then *data-readers* gets messed up somehow. The readers you define in data_readers.clj won't work even if you require their namespaces. For example:

$ find -type f
./src/foo/core.clj
./src/data_readers.clj
./src/user.clj

On a project I'm working on, this gives me an error:

$ clj -Sdeps '{:deps {trident/build {:local/root "/home/arch/dev/trident/target/build"}}}' \

Exception in thread "main" Syntax error compiling at (trident/build/util.clj:1:1).

(I have (:import (jnr.posix POSIXFactory))) in that file).
