Overview

The Transactions module provides a way to run blocks of code within a DynamoDB transaction.

DynamoDB supports two types of transactions: read-only and write-only. This module provides a unified interface to both.

Examples:

Rails-style transaction (defaults to write)

User.transaction do |t|
  t.save(user)
  t.create(Account, name: 'A')
end

Explicit write transaction

User.transaction.writing do |t|
  t.save(user)
  t.create(Account, name: 'A')
end

Explicit read transaction

users = User.transaction.reading do |t|
  t.find(User, '1')
  t.find(User, '2')
end
