Abstract: A method and a server to optimize query execution on a data store are disclosed. The query execution in the present disclosure is optimized by grouping one or more queries, requiring same portion of data from the data store, into one or more groups. Grouping of the one or more queries into the one or more groups is achieved from one or more metadata included in the one or more queries specified by a user who wishes to retrieve the results based on the one or more metadata. The one or more queries grouped under the one or more groups are executed that involves scanning of the data store only for once. In such way, each query is returned with required results from the data store with minimum latency.

Abstract: Embodiments of the present invention disclose a frequency mixing circuit and a method for suppressing local oscillation leakage in the frequency mixing circuit, where a mixed input signal and a local oscillation signal are involved, and local oscillation leakage can be effectively reduced by using a frequency mixing circuit whose structure is simpler and is easier to be implemented. The frequency mixing circuit includes a direct current bias circuit, where the direct current bias circuit includes a direct current bias voltage source used for reducing a local oscillation current. The frequency mixing circuit is mainly applied to frequency mixing, and especially to a case where an intermediate frequency signal is mixed with a local oscillation signal to output a radio frequency signal.
