Abstract: According to an aspect of the present disclosure, a query builder sends to a node in a cloud, a request for meta-data related to objects, and in response receives from the node, the meta-data specifying information related to objects exposed by the node. Upon receiving from a user a partial query and a current edit location during building of a corresponding complete query, the query builder determines, based on the received meta-data, the current edit location, and the partial query, a list of identifiers which are potential candidates for insertion at the current edit location. The query builder then displays the list of identifiers to the user, and receives a selection of an identifier from the displayed list. The query builder incorporates the selected identifier in the partial query at the current edit location to form a further developed query.

Abstract: Techniques are described for maintaining an expression statistics store that stores and updates metadata values for query expressions based on the occurrence of those query expressions within queries. In an embodiment, a database server instance receives a database query. In response, the database server instance identifies expressions within the database queries. The database server instance then determines whether an expression statistics store includes an entry for the particular expression. Responsive to determining that the expression statistics store includes an entry for the particular expression, the database server instance updates at least one metadata value in the entry based on the occurrence of the particular expression. Responsive to determining that the expression statistics store does not include an entry for the particular expression, the database server instance adds an entry for the particular expression.

Abstract: Techniques are disclosed for enabling tenant hierarchy information to be migrated directly between different multi-tenant system (e.g., from a shared IDM system to a Nimbula system, or vice versa). A corresponding new tenant is created in a Nimbula system based on a combination of the tenant information and the service information from the shared IDM system. The Nimbula system extracts the tenant name and the service name from a request and asks the shared IDM system to verify that the user actually is a member of the tenant identified by the extracted tenant name. Upon successful authentication of the user, the Nimbula system requests the IDM system for roles that are associated with both the user and the extracted service name. The Nimbula system enable access to the service upon determining whether the requested operation can be performed relative to the specified service based on the roles.

Abstract: Techniques are described for maintaining coherency of a portion of a database object populated in the volatile memories of multiple nodes in a database cluster. The techniques involve maintaining a local invalidation bitmap for which identifies block-level invalidity data and item-level invalidity data. In response to detecting a patch-up triggering event, a particular node identifies, in the block-level invalidity data, blocks that have been marked as invalid. For each block that has been marked as invalid, the node identifies specific items that have changed and marks the items as invalid in the item-level invalidity data. The node then updates the block-level invalidity data to indicate that the blocks are no longer invalid.

If it is, the query may be divided into two functions, an aggregate function and a global function. The aggregate functions may be distributed across multiple distributed nodes and executed in parallel. The global function may then receive the results from the distributed nodes and join the results to achieve the fully stateful result.

Abstract: Systems, devices, and methods of the present invention relate to detecting a request for explanation in text. In an example, a method creates a discourse tree from a subset of text. The discourse tree includes nodes, each nonterminal node representing a rhetorical relationship between two of the fragments and each terminal node of the nodes of the discourse tree is associated with one of the fragments. The method forms a communicative discourse tree from the discourse tree by matching each fragment that has a verb to a verb signature. The method further identifies that the subset of text comprises a request for an explanation by applying a classification model trained to detect a request for an explanation to the communicative discourse tree.

Abstract: The disclosed embodiments relate to a system that caches time-series data in a time-series database system. During operation, the system receives the time-series data, wherein the time-series data comprises a series of observations obtained from sensor readings for each signal in a set of signals. Next, the system performs a multivariate memory vectorization (MMV) operation on the time-series data, which selects a subset of observations in the time-series data that represents an underlying structure of the time-series data for individual and multivariate signals that comprise the time-series data. The system then performs a geometric compression aging (GAC) operation on the selected subset of time-series data. While subsequently processing a query involving the time-series data, the system: caches the selected subset of the time-series data in an in-memory database cache in the time-series database system; and accesses the selected subset of the time-series data from the in-memory database cache.

Abstract: The disclosed embodiments relate to a system that performs low-temperature desalination. During operation, the system feeds cold saline water through a liquid-cooling system in a computer data center, wherein the cold saline water is used as a coolant, thereby causing the cold saline water to become heated saline water. Next, the system feeds the heated saline water into a vacuum evaporator comprising a water column having a headspace, which is under a negative pressure due to gravity pulling on the heated saline water in the water column. This negative pressure facilitates evaporation of the heated saline water to form water vapor. Finally, the system directs the water vapor through a condenser, which condenses the water vapor to produce desalinated water.
