Abstract: Techniques are disclosed for storing and retrieving large amounts of data in a non-relational database using sort keys. A server computer system may receive a request for raw data specifying a start timestamp and an end timestamp. The server determines a start key and an end key for performing a query on a distributed non-relational database storing key-value pairs, where the determining is based on the start timestamp and the end timestamp. The server may compare the start key and the end key to a sort key included in row keys of key-value pairs stored in the non-relational database. Based on the comparing, the server retrieves one or more rows of raw data from the non-relational database. The server generates a graphical representation of the one or more rows of raw data retrieved from the non-relational database. The disclosed techniques may advantageously improve the efficiency of a database management system.

Abstract: Testing an integrated circuit (IC) that has a set of nominally similar cores and pairs of test data input (TDI) and test data output (TDO) pads common to the different cores. Similar scan chains in parallel in the different cores provide response signals as functions of corresponding TDI signals. Respective combined TDO signals are provided to the TDO pads. In the absence of a defect, the combined TDO signals are asserted and de-asserted like the response signals from corresponding chains in the different cores and like corresponding expected response signals. The combined TDO signals are different from the corresponding expected response signals in the presence of a defect in at least one of the cores. If the result is a fail, the ATE may identify a defective core using a diagnosis module in the IC providing response signals from a selected core.
