Abstract[English]
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.[French]
L'invention concerne des procédés et un système pour un système de gestion de base de données (SGBD), dans lesquels un fil chef est élu parmi des fils de transaction concurrents stockés dans un ou plusieurs nœuds de données. Tandis que le fil chef copie son propre journal de transactions de fil dans une partie réservée du tampon de journal partagé, le fil chef permet à d'autres fils de transaction de s'attacher à une chaîne de fils commençant par le fil chef. Une fois que le chef a terminé la copie de son journal de transactions de fil dans le tampon de journal partagé, il réserve ensuite une partie du tampon de journal partagé, et copie les journaux de transactions des fils membres dans le tampon de journal partagé, de manière à réduire la contention pour le tampon partagé.
