DATABASE CACHE SURVIVABILITY ACROSS DATABASE FAILURES

A database system may implement database cache survivability across database failures. In various embodiments, a database cache may be maintained independent of a failure of a database. A database cache may be maintained in a non-volatile memory device or maintained in a shared memory segment of system memory. Upon recovery from a database failure, a recovery point may be determined that indicates a consistent state of the database. Cache entries of the database cache inconsistent with the consistent state of the database may be invalidated, and the database cache may be made available for access requests directed toward the database. Valid cache entries from before the database failure may be made available without accessing a back-end data store for the database.
