1. A computer-implemented database management system having computer readable media that store executable instructions executed by a processor, comprising: a shared-nothing cluster that employs adaptive cloning to store database segments of a database across cluster nodes, each database segment having transaction log records that track changes of a transaction, the transaction log records formed into a transaction log stream; and a replication component that receives multiple transaction log streams of a database to create a change history of the changes, the replication component replicates the changes to a destination data system as a single stream of changes.
