数据节点是用命令ndbd启动的。 SQL节点:这是用来访问簇数据的节点。对于MySQL簇,客户端节点是使用NDB簇存储引擎的传统MySQL服务器。典型情况下,SQL节点是使用命令mysqld –ndbcluster启动的,或将ndbcluster添加到my.cnf后使用mysqld启动。 簇配置包括对簇中单独节点的配置,以及设置节点之间的单独通信链路。对于目前设计...
È possibile creare gli indici non cluster in SQL Server usando SQL Server Management Studio o Transact-SQL. Un indice non cluster è una struttura di indice separata dai dati archiviati in una tabella che riordina una o più colonne selezionate. Spesso gli indici non cluster consentono ...
only entire columns can be indexed. (The size of anNDBcolumn index is always the same as the width of the column in bytes, up to and including 3072 bytes, as described earlier in this section. Also seeSection 2.7.6, “Unsupported or Missing Features in NDB Cluster”, for additional info...
Se la tabella non contiene un indice cluster, le righe di dati vengono archiviate in una struttura non ordinata denominata heap. Non cluster Gli indici non cluster presentano una struttura distinta dalle righe di dati. Un indice non cluster contiene i valori di chiave dell'indice non...
MySQL NDB Cluster presents multiple interfaces to the database, enabling maximum developer agility, while also providing the option to bypass the SQL layer entirely for native, blazing fast access to your tables. Each of the SQL and NoSQL APIs can be used simultaneously, across the same data ...

All SQL nodes acting as sources and replicas are started with the system variable log_replica_updates (NDB 8.0.26 and later) or log_slave_updates (prior to NDB 8.0.26) enabled. This type of circular replication setup is shown in the following diagram: Figure...
