Question

How should I monitor the progress of a mapped function in clojure?

When processing records in an imperative language I often print a message every so often to indica

I have had this problem with some slow-running apps (e.g. database ETL, etc). I solved it by adding the function (tupelo.misc/dot ...) to the tupelo library. Sample:

(ns xxx.core 
  (:require [tupelo.misc :as tm]))

(tm/dots-config! {:decimation 10} )
(tm/with-dots
  (doseq [ii (range 2345)]
    (tm/dot)
    (Thread/sleep 5)))

Output:

     0 ....................................................................................................
  1000 ....................................................................................................
  2000 ...................................
  2345 total

API docs for the tupelo.misc namespace can be found here.
