Abstract: A data query method based on Doris includes: acquiring history data in a bottom operator in a storage engine architecture of the Doris, and performing an aggregation calculation on the history data to obtain an aggregation result of the history data; caching, by a preset cache system, the aggregation result of the history data; performing an aggregation calculation on real-time data in a newly inserted bottom operator in the Doris, in response to a data query request, to obtain an aggregate result of the real-time data; acquiring the aggregation result of the history data from the preset cache system, and merging the aggregation result of the history data with the aggregation result of the real-time data to obtain merged data; and sending, by a data sending operator in the Doris, the merged data to an upper layer of an execution engine, to output a final data query result.

Abstract: The present disclosure provides an array substrate and a method for fabricating the same, a method for detecting alignment accuracy, and a liquid crystal display panel, wherein a dummy color resist unit is disposed on a periphery of a display area of a substrate, and a side or a center point of the dummy color resist unit is designed to be at a predetermined distance from an adjacent signal line. Therefore, it is only necessary to measure a distance between the side or the center point of the dummy color resist unit and a signal line adjacent to it, and compare the measured distance with the predetermined distance to estimate alignment accuracy of color resist units. It is not necessary to dispose detection units in a non-display area of the array substrate so that an area of the non-display area can be reduced to achieve ultra-narrow frame design.
