Abstract

In one embodiment, the present invention includes a computer-implemented method comprising monitoring a first condition of an in-memory database. An in-memory data store stores an in-memory database. The method further comprises determining whether the first condition of the in-memory database meets a first defined criterion. If the first condition of the in-memory database meets the first defined criterion, the in-memory database is stored in a persistent data store as a storage based database. If a received query is a query of the storage based database, the query is executed using the storage based database. Metadata of the in-memory database is mapped into a metadata repository if the in-memory database is stored in the in-memory data store. Metadata of the in-memory database is remapped in the metadata repository if the in-memory database is stored in the persistent data store as the storage based database.
