METHOD FOR HANDLING WRITES IN DATABASE CLUSTERS WITH TEMPORARILY DISJOINT NODES

摘要

A method for use in a multi-cluster database arrangement is provided. A given transaction is received at a given node of the multi-cluster database arrangement. A database object being modified by the given transaction is determined, whilst executing the given transaction at the given node. Subsequently, a given owner cluster assigned to the database object is determined. Next, it is determined whether or not the given node is included in a primary component of the given owner cluster. The given transaction is committed at the given node for the given owner cluster, when the given node is included in the primary component of the given owner cluster. The aforementioned method is performed when the given transaction is received during a time the given node is communicably disjoint from at least one other node of the given owner cluster.
