Abstract: System and methods are described for synchronization of delete operations between primary a secondary databases. The method includes identifying a chunk of records in a secondary database. The method also includes sending a message to a primary database that identifies the chunk of records and asks whether any records of the chunk records are delete-able. The method also includes receiving a response to the message from the primary database. The response indicates which records of the chunk records are delete-able. The method also includes deleting each record of the chunk of records from the secondary database that the message indicated was delete-able.

Abstract: Examples include a computer-implemented method for determining one or more observations about a computing system, determining a plurality of sets of one or more actions based at least in part on a plurality of policies and the one or more observations; reducing the plurality of sets of one or more actions to generate a reduced set of actions, the reduced set of actions including scheduling a computing system to execute the reduced set of actions by requesting one or more idempotent tickets to be created in a ticketing system; and performing, or causing to be performed, the reduced set of actions.

Abstract: System and methods are described for restoring a database by receiving a request to restore a database in a cloud computing environment, generating a restore plan for the database based at least in part on previously stored database restore outcomes and error probabilities of full backups, incremental backups, and redo logs, restoring the database from an archive according to the restore plan, and storing an outcome of the database restore.

Abstract: Examples include a ticketing system for managing performance of computer services. The ticketing system includes a ticket database to store a plurality of tickets, each ticket defining a job to be performed on a computing system, and a master to create a ticket, store the ticket in the ticket database, and update the ticket. The ticketing system includes a scheduler to determine whether to create the ticket based at least in part on a set of conditions, and to request the master to create the ticket when the ticket is to be created, and a worker to get the ticket from the master, perform the job defined by the ticket, and request the master to update the ticket with a status of the ticket. The ticketing system includes a supervisor to request the master to find a stale ticket, and, if found, to request the worker to abort performance of the job defined by the stale ticket.
