Abstract: Batch processing of undo log records may be performed for rolling back a database transaction. When a rollback operation for a database transaction is performed, undo log records from an undo log to rollback the database transaction are divided into different groups of undo log records. Different requests for the different undo log records are sent to a storage system to be performed. If a conflict is detected for an undo log record in a group, an indication of the conflicting undo log record may be provided to indicate the conflict. The group of undo log records may be resent with a request to reapply the undo log records in the group. When all groups have been identified as successfully completed, then the rollback operation may be considered completed.

Abstract: Online restore operations for a database engine can be performed. A request to restore a database to a previous state can be received. Previously stored content of the database, such as snapshot stored prior to the previous state, can be identified along with log records describing changes to be made to the content prior to the previous state. State information in a query engine can be updated based on the previously stored content and log records so that queries can be processed based on the state information at the database restore to the previous state.

Abstract: Fine-grained virtualization provisioning may be performed for in-place database scaling. Computing resource utilization for a database on a host system is obtained for a period of time. The computing resource utilization may be evaluated with respect to a target capacity for the database. If a scaling event is detected based on the evaluation, a modified target capacity may be determined and used to make an adjustment of the computing resources permitted to be used by the database.

Abstract: Data pages of a database may be shared to create a copy of the database. A request to create a copy of the database may be received. Pointers to the data pages in the data store may be generated and stored as part of the copy of the database. When a request to read a data page in the copy of the database is received, the pointer to the data page may be accessed and the data page read from the database. When a request to modify a data page in the copy of the database is received, a modified version of the data page may be stored as part of the copy of the database and the pointer updated to point to the modified version of the data page.
