SimpleMysqlPartitioning

A Ruby gem that provides simple MySQL table partitioning functionality for ActiveRecord models. This gem allows you to easily manage RANGE partitions in MySQL databases through an intuitive Ruby API.

• Ruby 3.0 or higher
• Rails/ActiveRecord 6.1 or higher
• MySQL 8.0 or higher

This gem is tested against:

• Ruby: 3.0, 3.1, 3.2, 3.3
• Rails: 6.1, 7.0, 7.1, 7.2
• MySQL: 8.0

Add this line to your application's Gemfile:

gem 'simple_mysql_partitioning', '~> 2.0'

And then execute:

$ bundle

Or install it yourself as:

$ gem install simple_mysql_partitioning

class DailyReport < ActiveRecord::Base
  include SimpleMySQLPartitioning

  # arg1: column
  # type: partitiong type
  partitioning_by :day, type: :range
end


# partition name, less than value
pairs_name_with_values = [
  ['p201808', '2018-09-01']
]

# create partition
DailyReport.partition.create(pairs_name_with_values)

NOTE: No support MAXVALUE, please use add method after created partition.

# add partition
DailyReport.partition.add(pairs_name_with_values)

# reorganize partition
# If you want to reorganize partition, use this method and set reorganize partition name to second arg.
# Reorganize partitiong default value is 'MAXVALUE'.
DailyReport.partition.reorganize(pairs_name_with_values, 'p999999', 'MAXVALUE')

# drop
DailyReport.partition.drop('p201808')

# exists?
DailyReport.partition.exists?('p201808')

We support only range partitioning.
