Abstract
In one exemplary embodiment, a method includes the step of executing, with at least one processor, a main database node server in a source-database node of a source-database cluster. The main database node server manages database server operations. The main database node server communicates a source-database cluster state and a specified server operation metadata to a data-shipping daemon. The specified server operation metadata, includes an information about server operation occurring on the source-database node. Another step includes executing a data-shipping daemon in the source-database node. The data-shipping daemon receives the specified server operation metadata and stores the specified server operation metadata in a digest log. The data log includes a file of the specified server operation metadata. The data-shipping daemon reads the digest log and communicate data referred to in the specified server operation metadata in the digest log to a destination database node in a destination database cluster.
