Abstract
A method and apparatus for replicating data between heterogeneous databases is provided. Data is replicated between two heterogeneous databases with the use of a volatile storage queue, enabling the rapid replication of data across databases provided by different vendors or operating on different platforms. According to one embodiment, an in-memory queue is used to queue change operations to be performed on a target data repository. The change operations may be operations that were applied to a source data repository. An apply process retrieves the change operations from in-memory queue and commits the change operations to persistent storage. When the change operations have been committed, the apply process notifies the source platform that the particular change operation has been stored.
