Module: Provenance::TransactionKey

Defined in:
lib/provenance/transaction_key.rb

Overview

Builds the transaction key used to group changes inside the journal. A single format is shared across the gem (Trackable and BulkOperations); otherwise rollback cleanup (‘remove_changes_for_transaction`) would fail to match the paired records.
