WebWhat is a database cluster? Database clustering is the process of connecting more than one single database instance or server to your system. In most common database clusters, multiple database instances are usually managed by a single database server called the master. WebAttribute clustering works on direct path loads and data movement operations, so it is a more natural fit for data warehouses. It's possible to do join attribute clustering. Data from the joined tables is not stored in the clustered table, but the cluster order is determined by the join columns in data in joined tables.
