In an ion reflector (4) configured from a plurality of electrodes, electrodes 42 disposed in a second stage region (S2) for reflecting ions after deceleration are formed thinner than electrodes (41) disposed in a first stage region (S1) for decelerating the ions. The thin electrodes suppress unevenness of potential, in particular, in a path away from the center axis of the reflector, which results in improvement of isochronism of an ion packet passing on the path. The thick electrodes (41, 43) disposed in the first stage region (S1) prevents stretching of the grid electrodes (G1, G2) from being affected, and unevenness of potential in the first stage region (S1) hardly affects isochronism of the ions.

Since the number of electrodes in the first stage region (S1) can be reduced, an increase in costs is suppressed. Consequently, it is possible to bring an electric field of an ion reflection region closer to an ideal state and improve mass-resolving power while suppressing costs.

These rows may have known ‘weak’ cells that require refreshing more often than a majority of the other rows on the module (or component). By ignoring some auto-refresh commands, and directing some others to specific rows that have ‘weak’ cells, the power consumed by refresh operations can be reduced.

A system that implements a data storage service may store data in multiple replicated partitions on respective computing nodes on behalf of clients. A storage node may, based on the amount of provisioned resources on a given storage device or logical volume, identify candidate partition management operations to be performed, and may send information about the operations to a central partition management scheduler. The scheduler may apply a global prioritization scheme to determine an order in which to perform the candidate operations. The order may be based on whether the operations include partition splits or partition moves, whether they aim to reduce provisioned storage capacity or reduce throughput capacity on a storage device or logical volume, whether they conflict with each other, whether the total number of partitions (or replicas thereof) involved in partition management at any given time exceeds a pre-determined limit, or whether they were requested by clients.

Systems and methods are disclosed herein for identifying an application for opening a file. A first user input indicative of a file selected by a user is received over a user interface. The selected file has an input file type and is an attachment to an email. Data indicative of the input file type is transmitted over a communications network. A reference list of applications is obtained by combining association requests from application developers to associate respective applications with one or more file types, and a matched list is obtained by removing applications from the reference list, each of the removed applications being associated with a set of one or more file types that each mismatch the input file type. The matched list is displayed over the user interface, which receives a second user input indicative of a selected application from the matched list.

High performance index creation using parallel query plans with repartitioning scan and vector-based repartitioning scan is described. An example method includes extracting index key columns from data rows of the database table to build a set of index rows, wherein the index on the database table is defined by a plurality of index key columns including a first index key column and a second index key column. Partition boundary values are generated to divide up the index rows into range-partitioned sets, and the index rows are sorted based on values of the index key columns. A repartitioning scan, including a SARG-based or a vector-based partitioning scan is performed on the index rows, using a plurality of worker threads executing in parallel to build sub-indexes. Subsequently, each range-partitioned set of index rows are assigned to a worker thread in the plurality of worker threads. Accordingly, the sub-indexes generated from the plurality of work threads are merged to build the index for the database table.

Systems, methods, and machine-readable memories are provided for partitioning a multi-tenant database between tenants. A first level partition of data in a table within the database is defined. A second level partition of the data in the table within the database is defined. A request is received from an entity associated with a tenant to access a first datum stored in the database. The tenant is determined to be assigned to one or both of the first level partition and the second level partition. Access to the first datum is granted to a first entity where the tenant corresponds to the first tenant and the first datum corresponds to the first level partition parameter value. Access to the first datum is granted to a second entity where the tenant corresponds to the second tenant and the first datum corresponds to the second level partition parameter value.

A method, computer system, and computer program product for managing copies of data objects in a network data processing system. The computer system identifies copies of a data object stored on storage devices. The computer system places the storage devices into groups. Each storage device in a group has a smallest distance from the storage device to a center location for the group as compared to distances to center locations for other groups within the groups. The computer system selects a portion of the copies of the data object for removal from the storage devices based on a management of power for the storage devices such that remaining set of storage devices in each group is capable of handling concurrent requests that have been made historically for the copies of the data object. The computer system removes the portion of the copies of the data object from the storage devices.

Techniques for dynamic delivery of client-indicated source data to an impact-on-demand or mapping system include a dynamic data delivery module configured to automatically transform the source data into a format that is compatible with the mapping system, validate at least a portion of the source data, and cause the transformed, validated source data to be delivered to the mapping system for storage in a client portfolio. The mapping system may, in real-time, map the client portfolio with impact events to determine risk exposure. The transformation may be based on one or more rules corresponding to the mapping system, and multiple original source data formats may be automatically transformed into the target format. The dynamic data delivery module may automatically correct or adjust source data contents or format to mitigate any anomalies or errors discovered during the transformation and/or validation processes.
