Abstract: Systems and methods for generating a platform-independent metadata catalog framework of a database system are disclosed. These include receiving, at the database system, a metadata object, and determining a version of the received metadata object. Responsive to determining that a metadata catalog, which has catalog entries associated with unique versions of metadata objects, does not include a catalog entry associated with the version of the received metadata object, a catalog entry in the metadata catalog is created. The created catalog entry is then associated with the version of the received metadata object. Furthermore, a version number based on the version of the received metadata is generated, which is associated with the created catalog entry. Related apparatus, systems, techniques and articles are also described.

Abstract: Systems and methods include reception of a request to move a first database tenant from a first database instance to a second database instance, the first database tenant comprising a first tenant object instance associated with a plurality of artifacts of the first database instance, the plurality of artifacts including a tenant-level catalog and data. In response to the request, the tenant-level catalog is exported from the first database instance to a shared storage system, the tenant-level catalog is imported to a second tenant of the second database instance from the shared storage system, the data is exported from the first database instance to the shared storage system, the data is imported to the second tenant of the second database instance from the shared storage system, and the first database tenant is dropped from the first database instance.

Abstract: Systems and methods include reception of an instruction to recover a first database tenant of a first database instance to a first point in time, the first database tenant associated with first database artifacts of the first database instance, and the first database instance including two or more database tenants and, in response to the instruction, creation of a second database instance, selection of backup data of the first database instance based on the first point in time, execution of a recovery of the backup data on the second database instance, export of second database artifacts of the first database tenant from the second database instance to a storage, truncation of the first database artifacts from the first database instance, import of the second database artifacts from the storage to the first database instance, and deletion of the second database instance.

Abstract: Systems and methods include creation of a first instance of a tenant object in a database instance, association of the first instance of the tenant object with a first plurality of database artifacts including first data associated with the first instance of the tenant object, creation of a second instance of the tenant object in the database instance, association of the second instance of the tenant object with a second plurality of database artifacts including second data associated with the second instance of the tenant object, and reception and response to queries on the first data associated with the first instance of the tenant object and to queries on the second data associated with the second instance of the tenant object.

Abstract: Systems and methods for generating a metadata log in a database recovery system include generating, at its primary system, a metadata log for a logging period. A change applied to a metadata object accessible from the primary system is detected, and upon detection, the system identifies a pair of a unique metadata identifier and a metadata type for the changed metadata object and determines a metadata structure of the changed metadata object. A data exchange object for the metadata structure is generated and a data exchange element from the data exchange object is created. The metadata log is updated with log information that includes the data exchange element and the pair, which is associated with the data exchange element. Upon the logging period ending, the metadata log is transmitted to a secondary system of the database recovery system for replaying. Related apparatus, systems, techniques and articles are also described.
