Title:
TRANSACTION PROCESSING METHOD AND APPARATUS, AND NODE AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/026784
Kind Code:
A1
Abstract:
The present application belongs to the technical field of data access. Disclosed are a transaction processing method and apparatus, and a node and a storage medium. In the embodiments of the present application, a first node reads a write object from a second node and reads a read object from a third node, and after modifying a data item of the write object, the first node sends a write lock message to the second node and sends a read lock message to the third node. In this way, the second node and the third node can lock objects and verify version values of the objects in any particular order. Compared with verifying a version value of a read object after a write object is successfully locked and passes version value verification, the duration for transaction processing is shortened. Moreover, even if the third node successfully verifies the version value of the read object before the second node successfully locks the write object, a read lock is successfully configured for the read object when the read object passes the version value verification, and therefore the read object is not tampered with by other transactions until the second node successfully configures a write lock for the write object, thereby ensuring the correctness of submitted data.
