Zusammenfassung:Methods, systems, electronic devices and computer-readable media for database transaction processing are provided. In an example, after determining to perform primary-secondary switching of a copy, a first server records a context of a database transaction that is currently being executed, sends the context to a second server, and switches a primary copy stored in the first server to a secondary copy. The second server switches a secondary copy stored in the second server to a primary copy, and continues execution of the database transaction based on the context after completing the switching.
