# This script is a proof of concept to show how to use ActiveSupport::Concern 
# to manage dependencies between modules and classes. The main idea is to use 
# the included block to include the dependencies of a module, and the 
# class_methods block to define class methods.
# 
# Ultimately, the script prints all of the the methods of the Host, Bar, and 
# Foo classes and modules to show the result of the concern implementation.

# This gist documents a frequently thed pattern of decorating multiple classes with Logging methods 
# by sharing just one Logger typically at the top of the module namespace (Application) in this case.

# If the concurrency issues come up, each class can be given its own logger, or perhaps the Logging moduloe
# might have decorators for each of the logging methods (eg #info, #debug) by using a Mutex.
#
# The output of this Ruby Code should be as follows:

-- This file requires a local SQL file named "json_table_columns.csv" to have two columns: 
--    [ "Table", "Column" ]
-- It then loops over records in this table computing the total size of the column in each table, 
-- the average size of the column in that table, and finally the percentage that column occupies relative
-- to the entire table (including its indexes).


-- First we import the data
BEGIN;
    drop table if exists JSON_TABLE_COLUMNS;
