We initially aimed at implementing data archiving in production reusing this rake task but priorities have changed. It'll be just a refactor for now.

|
|
# This task can be used to significantly reduce the size of a database
|
|
# This is used for example when loading live data into a staging server
|
|
# This way the staging server is not overloaded with too much data
|
|
#
|
|
# This is also aimed at implementing data archiving. We assume data older than
|
|
# 2 years can be safely removed and restored from a backup. This gives room for
|
|
# hubs to do their tax declaration.
|
|
#
|
|
# It's a must to perform a backup right before executing this. Then, to allow
|
|
# for a later data recovery we need to keep track of the exact moment this rake
|
|
# task was executed.
|
|
#
|
|
# Execute this in production only when the instance users are sleeping to avoid any trouble.
|
|
#
|
|
# Example:
|
|
#
|
|
# $ bundle exec rake "ofn:data:truncate[24]"
|
|
#
|
|
# This will remove data older than 2 years (24 months).
