Abstract
Methods and system for a database management system (DBMS) in which a leader thread is elected from concurrent transaction threads stored in one or more data nodes. While the leader thread copies its own thread transaction log onto a reserved portion of the shared log buffer, the leader thread permits other transaction threads to attach to a thread chain starting with the leader thread. Once the leader has completed copying its thread transaction log onto the shared log buffer, it then reserves a portion of the shared log buffer, and copies the member thread transaction logs onto the shared log buffer to reduce the contention for shared buffer may be reduced.
