Abstract: 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.

Abstract translation: 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 。

Abstract: A database system includes a persistent storage system, a memory storing metadata defining a tenant object and a plurality of database artifacts, a first instance of the tenant object, the first instance associated with a first plurality of the database artifacts including first data associated with the first instance of the tenant object, and a second instance of the tenant object, the second instance associated with a second plurality of the database artifacts including second data associated with the second instance of the tenant object. A processing unit is to execute program code of a database instance to cause the database system to encrypt the first data associated with the first instance of the tenant object using a first public encryption key and store the encrypted first data in the persistent storage system, and encrypt the second data associated with the second instance of the tenant object using a second public encryption key and store the encrypted second data in the persistent storage system.
