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 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: Replicating a tenant database includes receiving at a source system a first request from a target system for replicating a first tenant database of the source system, which includes one or more first servers. Characteristics of the one or more first servers are sent to the target system to generate at the target system a second tenant database including one or more second servers. Each second server corresponds to one first server and has the same characteristics as the corresponding first server. Information from each first server is replicated, in an asynchronous mode, to the corresponding second server through a communication channel that is established between each first server and the second server. Upon receiving a second request for stopping the replication, a synchronous mode of processing statements from client applications of the first tenant database is entered. Related apparatus, systems, techniques and articles are described.
