Abstract: A storage tier manager efficiently creates different representations of a dataset backup for different retention periods. Each of the representations of the dataset backup is distinctly identifiable despite initially representing a same dataset backup. The representations are structured metadata corresponding to the dataset backup. One representation is a cached backup version of the dataset backup (“cached backup” or “cached representation”) provided for low latency access while residing at a storage tier of the backup appliance for a relatively short retention period according to a lifecycle management policy. The other representation is a cloud backup version of the dataset backup (“cloud backup” or “cloud representation”) provided for persisting into cloud storage for a longer retention period according to the lifecycle management policy.

Abstract: Techniques are described herein for building a framework for declarative query compilation using both rule-based and cost-based approaches for database management. The framework involves constructing and using: a set of rule-based properties tables that contain optimization parameters for both logical and physical optimization, a recursive algorithm to form candidate physical query plans that is based on the rule based tables, and a cost model for estimating the cost of a generated physical query plan that is used with the rule based properties tables to prune inferior query plans.

Abstract: System and method embodiments are provided for using different storage formats for a primary database and its replicas in a database managed replication (DMR) system. As such, the advantages of both formats can be combined with suitable design complexity and implementation. In an embodiment, data is arranged in a sequence of rows and stored in a first storage format at the primary database. The data arranged in the sequence of rows is also stored in a second storage format at the replica database. The sequence of rows is determined according to the first storage format or the second storage format. The first storage format is a row store (RS) and the second storage format is a column store (CS), or vice versa. In an embodiment, the sequence of rows is determined to improve compression efficiency at the CS.

Information about source databases can be received from a source system, including source hardware types and processor information for the source databases. Each of the source databases can be classified to one of a plurality of predetermined database sizes based on the received information. The source system can be interrogated to derive information about the source databases, such as a processor utilization per database. Characteristics of the classified database sizes can be adjusted based on the derived information and resource requirements at a target system for the classified source databases can be determined. A shape for the target databases can be generated based on the resource requirements, the shape including target databases of predetermined database sizes implemented by target hardware, where the target databases are configured to receive migration data from the source databases.

Abstract: Techniques for patching metadata content in a base repository are disclosed. Techniques can include customizing, by a computer including a processor and a memory, metadata content in an existing base repository, consolidating the metadata content customized in the existing base repository into a consolidated customization file, obtaining a new version of a base repository, transforming the metadata content in the consolidated customization file in accordance with the new version of the base repository and applying the transformed metadata content to the new version of the base repository. Transformation can be performed in response to metadata content being renamed, recreated and deleted.

Abstract: A mechanism is provided for re-ranking search results based on a personal medical condition. One or more medical conditions associated with a patient are identified based on an analysis of patient information associated with the patient. The one or more medical conditions are correlated with a set of medical condition content indicator data structures. A search query corresponding to the patient is processed to generate initial search results that are ranked with an initial ranking. The initial search results are analyzed based on a patient specific dictionary data structure corresponding to the one or more medical conditions associated with the patient. The content of the initial search results are re-ranked to generate re-ranked search results having a modified ranking that is based on the one or more medical conditions of the patient. The re-ranked search results are output to the patient in accordance with the modified ranking.

During creation of the secondary index, creation progress points that indicate the progress of the indexing across the table partitions may be determined. The creation progress points may be provided via a programmatic, textual, or graphical interface to the distributed data storage system.
