Abstract: Transformation configuration data is set for a consumer replication set on a consumer instance to replicate on the consumer instance data of a source table included in a producer replication set on a producer instance. The transformation configuration data includes configuration data of at least one of: (i) a target table from among a plurality of tables on the consumer instance that is specified in the consumer replication set as a table for loading on the consumer instance, incoming data from the source table; and (ii) a specified mapping of incoming fields of the source table with respective fields of the target table. Replication event data of a data modification event associated with a record on the source table is received. The received replication event data is transformed based on the set transformation configuration data, and loaded on the target table.

Abstract: A failure resistant distributed computing system includes primary and secondary datacenters each comprising a plurality of computerized servers. A control center selects orchestrations from a predefined list and transmits the orchestrations to the datacenters. Transmitted orchestrations include less than all machine-readable actions necessary to execute the orchestrations. The datacenters execute each received orchestration by referencing a full set of actions corresponding to the received orchestration as previously stored or programmed into the computerized server and executing the referenced full set of actions. At least one of the orchestrations comprises a failover operation from the primary datacenter to the secondary datacenter. Failover shifts performance of task from a set of processing nodes of the primary datacenter to a set of processing nodes of the secondary datacenter, such tasks including managing storage accessible by one or more remote clients and running programs on behalf of remote clients.

Abstract translation: 防故障分布式计算系统包括主要和次要数据中心，每个数据中心包括多个计算机化的服务器。 控制中心从预定义的列表中选择业务流程，并将业务流程传输到数据中心。 传输的业务流程包括少于执行业务流程所需的所有机读操作。 数据中心通过将先前存储或编程到计算机化服务器中的所接收的编排相对应的完整动作集合执行每个接收到的编排，并执行所引用的全部动作。 至少有一个业务流程包括从主数据中心到辅助数据中心的故障转移操作。 故障转移将任务的性能从主数据中心的一组处理节点转移到辅助数据中心的一组处理节点，这些任务包括管理一个或多个远程客户机可访问的存储器和代表远程客户端运行程序。
