  • Publication number: 20190188309
    Abstract: A system and a method for keeping two versions of a mirrored database in sync is provided. A connection is monitored between a primary database and a secondary database. When a loss of the connection between the primary database and the secondary database is detected, the primary database is monitored for changes. When a modification is detected to at least one row in the primary database, a value of a change indicator is changed for the corresponding row indicating that the row was modified. Once the connection between the primary and the secondary databases is restored, the primary database is queried for the value of the change indicator indicating the corresponding row was modified to obtain a current value for data in the corresponding row of the primary database, and the corresponding row in the secondary database is updated with the current value for the corresponding row.

  • Publication number: 20190163635
    Abstract: Embodiments are provided for deferring allocation of storage for segments. The method includes receiving, at a first moment in time, a request to allocate a first segment within a memory. Information corresponding to the first segment is stored in a first entry in a hash table, and memory is allocated for the first segment. Information about the first segment is returned to an entity that requested the allocation of the first segment, where the first segment is not allocated auxiliary storage until predefined criteria are satisfied. At a second moment in time, upon receiving an indication to deallocate the first segment, memory corresponding to the first segment is deallocated, where the first segment is never allocated auxiliary storage and the first entry in the hash table is deleted.
