Long-running transaction

From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by DJSoundDog (talk | contribs) at 04:44, 15 January 2021 (Added reference to the original paper which introduced the term 'saga' to this context, as well as the use of an execution controller. Removed reference to a penalty fee for cancellation of a hotel reservation as it is not relevant to the topic.). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

Long-running transactions (also known as the saga interaction pattern[1][2] ) are computer database transactions that avoid locks on non-local resources, use compensation to handle failures, potentially aggregate smaller ACID transactions (also referred to as atomic transactions), and typically use a coordinator to complete or abort the transaction. In contrast to rollback in ACID transactions, compensation restores the original state, or an equivalent, and is business-specific. For example, the compensating action for making a hotel reservation is canceling that reservation.

A number of protocols have been specified for long-running transactions using Web services within business processes. OASIS Business Transaction Processing[3] and WS-CAF[4] are examples. These protocols use a coordinator to mediate the successful completion or use of compensation in a long-running transaction.
