Abstract: A database system could include a first database engine, a second database engine, and a replication engine. The database system could also include processors configured to perform operations. The operations could involve obtaining indicators that are respectively associated with performance issues that can occur in the database system, each indicator defining one or more conditions that, when satisfied, cause the indicator to become active. The operations could also involve obtaining mappings between: (i) at least some of the indicators, and (ii) remediation subroutines.

Abstract: A secondary location is configured as a recovery service for a primary location of the service. The secondary location is maintained in a warm state that is configured to replace the primary location in a case of a failover. During normal operation, the secondary location is automatically updated to reflect a current state of the primary location that is actively servicing user load. Content changes to the primary location are automatically reflected to the secondary location. System changes applied to the primary location are automatically applied to the secondary location. For example, removing/adding machines, updating machine/role assignments, removing adding/database are automatically applied to the secondary location such that the secondary location substantially mirrors the primary location. After a failover to the secondary location, the secondary location becomes the primary location and begins to actively service the user load.

Abstract: Examples disclosed herein may involve a computing system that is operable to (i) present, via a visual interface, a virtual shape associated with a three-dimensional (3D) coordinate system, (ii) present, via the visual interface, a visual indicator positioned in proximity to the virtual shape and indicating that a specified spatial parameter of the virtual shape will be modified along a specified dimension of the 3D coordinate system in response to a given type of user input associated with the visual indicator, (iii) while presenting the visual indicator, detect an instance of the given type of user input associated with the visual indicator, and (iv) after detecting the instance of the given type of user input, update the virtual shape that is presented via the visual interface by modifying the specified spatial parameter of the virtual shape along the specified dimension.

Abstract: A magnetic patch system includes a sealing member configured for attachment to a pipeline proximate to a breach in a wall of the pipeline. A magnet is positioned at least partially within a housing arrangement. The magnet may be oriented to generate a force toward the wall of the pipeline to attach the housing arrangement to the wall of the pipeline and capture the sealing member between the housing arrangement and the wall of the pipeline. The system may be installed inside a pipeline using a remotely controlled robotic system.

Abstract: A processor may receive a request with a column-oriented operation. The query request may be related to updates to a row-oriented database based on the query request previously performed on the row-oriented database. The processor may determine the amount of time for replicating the updates to a column-oriented database. If the amount of time for replicating the updates to the column-oriented database is greater than a threshold amount of time, then the processor may create a transient file with the updates. The transient file may be in a format that is recognized by the column-oriented database. The processor may query the column-oriented database based on the query request and the transient file.

Abstract: Systems and method for improving query performance by querying an appropriate database engine based on the operation of the query request is provided. In one aspect, this approach involves querying a row-oriented database, querying a column-oriented database, or blacklisting the query request. In particular, updating the column-oriented database involves delete and insert operations. By maintaining updated databases and querying appropriate database engines, the response time of a query request may be improved.

Abstract: Systems, methods, and non-transitory computer-readable media can access a plurality of parameter-based encodings providing a structured representation of an environment captured by one or more sensors associated with a plurality of vehicles traveling through the environment. A given parameter-based encoding of the environment identifies one or more agents that were detected by a vehicle within the environment and respective location information for the one or more agents within the environment. The plurality of parameter-based encodings can be clustered into one or more clusters of parameter-based encodings. At least one scenario associated with the environment can be determined based at least in part on the one or more clusters of parameter-based encodings.

Abstract: Systems, methods, and non-transitory computer-readable media can determine sensor data captured by at least one sensor of a vehicle while navigating an environment over a period of time. Information describing one or more agents associated with the environment during the period of time can be determined based at least in part on the captured sensor data. A parameter-based encoding describing the one or more agents associated with the environment during the period of time can be generated based at least in part on the determined information and a scenario schema, wherein the parameter-based encoding provides a structured representation of the information describing the one or more agents associated with the environment. A scenario represented by the parameter-based encoding can be determined based at least in part on a cluster of parameter-based encodings to which the parameter-based encoding is assigned.

Abstract: A system for servicing cable includes a field-end assembly and a live-end assembly, each mounted on a support structure having at least one drive mechanism operable to cause relative linear movement between the field-end assembly and the live-end assembly. A drilling-and-shorting assembly can create a short circuit in a field-end of the cable, and a continuity tester can test the integrity of the short-circuit. The field end of the cable can then be ejected from the system, and an end-cap-cradle assembly can position an end cap on a live end of an electrical cable and test its installation.
