Abstract: The present disclosure is directed to updating a multi-tenant database concurrent with tenant cloning. In some embodiments, a computer system receives a request to perform an update operation on a multi-tenant database. The update operation includes updating database entries for a plurality of tenants. Responsive to receiving the request, the update operation is initiated. Performing the update operation includes accessing a list identifying database entries awaiting the updating. During the accessing of the list, the update operation holds a lock. When the lock becomes available for acquisition, a clone process is permitted to create, during performance of the update operation, a clone of a tenant's data within the database.

Abstract: Systems, devices, and techniques are disclosed for identification of records for post-cloning tenant identifier translation. Records may be received from a database system executing a database executor at a computing device executing a database application. The database application may identify, from among the records, records that include a record header that includes a bit indicating that an encoded value of a tenant identifier is stored in the record in a column of the record that is not a tenant identifier column. The database application may generate an index based on the records identified by the database application. The database application may access the records using the index and replace the encoded value of the tenant identifier stored in columns of the records with an encoded new value of a tenant identifier.
