Abstract[English]
Provided are a DDL statement processing method and system, a device, and a storage medium, comprising: a computing node sending to a storage node a first indicating signal used for indicating entry into a target processing phase of a DDL statement. By means of a control thread, the storage node sending to at least one DDL thread corresponding to at least one physical sharding a first notification signal corresponding to the first indicating signal, so as to execute a processing behavior corresponding to the target processing phase by means of the at least one DDL thread, and sending a second notification signal to the control thread after executing the processing behavior; and, by means of the control thread, sending to the computing node a second indicating signal indicating that the at least one DDL thread is sending a second notification signal, and the computing node determining an execution state of the DDL statement according to the second indicating signal.[French]
L'invention concerne un procédé et un système de traitement d'instruction DDL, un dispositif et un support de stockage, le procédé comprenant l'étape dans laquelle : un nœud informatique envoie à un nœud de stockage un premier signal d'indication utilisé pour indiquer une entrée dans une phase de traitement cible d'une instruction DDL. Au moyen d'un fil de commande, le nœud de stockage envoie à au moins un fil DDL correspondant à au moins une fragmentation physique d'un premier signal de notification correspondant au premier signal d'indication, de façon à exécuter un comportement de traitement correspondant à la phase de traitement cible au moyen dudit au moins un fil DDL, puis envoie un second signal de notification au fil de commande après l'exécution du comportement de traitement ; et, au moyen du fil de commande, envoie au nœud informatique un second signal d'indication indiquant que ledit au moins un fil DDL envoie un second signal de notification, puis le nœud de calcul détermine un état d'exécution de l'instruction DDL selon le second signal d'indication.[Chinese]
提供一种 DDL 语句处理方法、系统、设备和存储介质，包括：计算节点向存储节点发送用于指示进入 DDL 语句的目标处理阶段的第一指示信号。存储节点通过控制线程分别向至少一个物理分片对应的至少一个 DDL 线程发送与第一指示信号对应的第一通知信号，以通过至少一个 DDL 线程执行目标处理阶段对应的处理行为，并在执行完处理行为后分别向控制线程发送第二通知信号；通过控制线程向计算节点发送指示至少一个 DDL 线程均发出第二通知信号的第二指示信号，计算节点根据第二指示信号确定 DDL 语句的执行状态。.
