Abstract: A database includes a plurality of partitions with respective partition dates. A query is received for data from a view of the database, the query containing a filtering parameter for retrieval of the data. A definition of the view is analyzed to determine a table of the database that contributes to the view and an aging object associated with the table. A restriction rule associated with the aging object is identified, for example, based on an annotation in the definition of the view. A restriction date for the aging object is determined based on the restriction rule. A partition, from the plurality of partitions, is selected based on the partition date of the partition being equal to or later than the restriction date. The queried data is retrieved from the selected partition according to the filtering parameter and a response to the query is generated based on the retrieved data.

Abstract: Various embodiments of systems and methods to optimize compilation in distributed software projects via dynamic server cloning are described herein. The described techniques include receiving a compilation request comprising an update of a software product of a distributed software development project. Further, in one aspect, a server node clone is instantiated, e.g., from a resource pool, based on a server template. The server template corresponds to a latest successful compilation of the software product. In another aspect, the update of the software product is incrementally applied on the latest compilation at the server node clone. Once the update of the software product at the server node clone is confirmed as successful, the server template is updated to the build of the software product at the server node clone. The server node clone is subsequently released to the resource pool to free up the consumed resources.

Abstract: Example embodiments of a database employing an efficient form of multi-version concurrency control (MVCC) are described. In an example embodiment, in response to receiving an update command for a first row of a plurality of rows of a database, an image of the first row stored in a first memory area is stored in a second memory area. In a third memory area storing a first database structure and associated pointer corresponding to the image of the first row stored in the first memory area, a second data structure and associated pointer corresponding to the image of the first row in the second memory area are stored. The second data structure is linked to the first data structure. The image of the first row in the first memory area is overwritten with an image of a new version of the first row provided in the update command.

Abstract: A hybrid database table is stored as both a row and a column store. One or more techniques may be employed alone or in combination to enhance performance of the hybrid table by regulating access to, and/or the size of, the processing-intensive column store data. For example during an insert operation, the column store data may be searched for a uniqueness violation only after certain filtering and/or boundary conditions have been considered. In another technique, a hybrid table manager may control movement of data to the column store based upon considerations such as frequency of access, or underlying business logic. In still another technique, querying of the hybrid table may result in a search of the column store data only after an initial search of row store data fails to return a result.

Abstract: Technologies for performing garbage collection in database systems, such as multi-version concurrency control (MVCC) database systems, are described. For example, different garbage collection techniques can be used separately or in various combinations, including interval garbage collection, group garbage collection, table garbage collection, and combinations. For example, a particular type of combination, called hybrid garbage collection, uses technique from interval garbage collection and group garbage collection, or from interval, group, and table garbage collection.

Abstract: Network packets containing data of a data request received from a client machine by a leader replica of a cluster of replicas can be passed to follower replicas of the cluster, and a replicate request can be sent to the follower replicas after the network packets have been sent to the follower replicas. A mutation required by the data request can be recorded as committed upon receipt of replication confirmation messages from a quorum of the replicas, and the client machine can be notified that the mutation has been completed after the recording of the mutation as committed. In one option, the client machine can send the network packets to the leader replica, which in turn sends these network packets to the follower replicas. In another option, the client machine can send the network packets to the leader replica and to the follower replicas.

Abstract: A data validation procedure may be propagated to a server machine and to a client machine to perform the same data checking in the respective machines. The data validation procedure may be converted and expressed in a specification language that is suitable for the server machine. Likewise, the data validation procedure may be converted and expressed in a specification language that is suitable for the client machine.
