Abstract
A database management system receives a request to execute a long-running transaction. The database management system sub-divides the transaction into a plurality of sub-transactions. The transaction is initiated using optimistic locking. The database management system attempts to execute and validate the sub-transactions. When a sub-transaction fails, it is re-executed after a delay period. When all sub-transactions have been executed and validated, the transaction commits.
