摘要： Tables in a distributed database can require redistribution, for example to provide improved collocation of tables or table partitions that require joining at a node of multiple nodes across which the distributed database is distributed. Based at least in part on a set of table redistribution parameters, a table redistribution plan can be generated to include redistribution of a table from a first node to a second node. The set of table redistribution parameters can include a grouping parameter indicating at least one other table with which the table should be collocated. The table redistribution plan can be executed to cause the moving of the table from the first node to the second node.

摘要： A node type of a plurality of distributed nodes to which a table to be added to a distributed database should be assigned can be identified by applying a set of placement rules defined for the table. The set of placement rules can also be applied to determine whether the table should be partitioned into more than one partition. A table group name associated with the table can be obtained and used in conjunction with the node type and determination of whether to partition the table to store the table in the distributed database on at least one node of the plurality of nodes as one or more partitions.
摘要翻译： 可以通过应用为表定义的一组放置规则来识别要分配要添加到分布式数据库的表的多个分布式节点的节点类型。 还可以应用这套放置规则来确定表是否应该被分割成多个分区。 可以获得与表相关联的表组名称，并与节点类型一起使用并确定是否划分表以将表在多个节点中的至少一个节点上存储在分布式数据库中作为一个或多个分区 。
