Abstract
Cluster nodes are allowed to start transactions involving modifications to multiple entities by locking a current entity for a current modification associated with a transaction, but not locking a subsequent entity for a subsequent modification associated with the same transaction. Undo log records are generated to allow the modifications to be rolled back. When a lock being held by a first node for a first transaction involving a modification made to an entity is requested by a second node for a second transaction involving the same entity, an undo record is persisted to a log to allow the modification to be rolled back, the lock being held by the first node is revoked and provided to the second node. Upon a determination that the first node has crashed before the first transaction could be committed, the log is replayed to undo the modification made by the first node.
