Transaction Support

Transaction Processing

The CUBRID SHARD executes an internal processing procedure to guarantee atomicity among ACID. For example, when an exception such as abnormal termination of an application occurs, the CUBRID SHARD sends a request to rollback to the shard DB which has been processing the request from the application in order to invalidate all changes in the transaction.

The ACID, the characteristic of general transactions, is guaranteed, based on the characteristics and settings of the backend DBMS.


2 Phase Commit (2PC) is unavailable; therefore, an error occurs when a query is executed by using several shard DBs in a single transaction.
