摘要： A distributed database transaction coordination manager's outcome store may be unavailable to resolve in-doubt transactions locally, e.g., after an unclean detach, during an outcomes store restore, or during a logical database restore. To facilitate transactional consistency, AGEs and values based on them are used. Some code avoids reformatting any closed physical portion for reuse based on the segment's most recently received minimum of persisted AGEs. Some code commits any in-doubt transactions that appear on an aggregate list and aborts any not on the aggregate list. Some code writes each segment's transaction commit records to persistent storage until the segment's persisted-AGE is not less than a common-restore-AGE, and some code resolves any in-doubt transactions based on a harvested outcomes list. Outcomes may reside in a log or a persisted transactions table. A restore checkpoint may include harvested outcomes. Segments may reside on cloud nodes and/or in a shared nothing database system.

摘要： Embodiments described herein are directed to the accessing remotely stored binary object data in a binary object store. In one embodiment, a computer system receives a request for a portion of binary object data, sends a query to a database server requesting access to the binary object data, and receives a binary object reference. The binary object reference includes binary object identification data and use characteristics specific to the binary object store. The computer system sends a binary object data access request based on the binary object reference to the binary object store using a binary object store interface, and receives the binary object data corresponding to the binary object data access request. The binary object data comprises a portion of data files. The computer system also sends the received binary object data to the user.

摘要： Methods, systems, and computer-readable media of data storage that include storing page identities of individual pages and logical relationships between pages are disclosed. A particular system includes a plurality of data storage devices. A storage manager is configured to store data as pages at the data storage devices. Each page includes a page payload and a page identity. The storage manager is also configured to store one or more relationships indicating logical order between pages.
