Abstract

The invention discloses a data search method and device and a storage medium, and the method comprises the steps: receiving a search request, reading table files according to the search request, and creating a corresponding search task for each table file according to the search request; obtaining the predicted completion time of the search task on each computing device, and selecting the computing device with the minimum predicted completion time value as the computing device of the search task; the search tasks are added to a task queue of the computing device, data loading of all the search tasks on the task queue is completed in sequence through a loading thread on CPU resources, and corresponding data block files are obtained; and reading the data block file from the memory into a video memory by utilizing the GPU resource, executing a search task corresponding to the data block file according to the GPU resource, returning a search result obtained by execution to the memory, and merging all the search results to obtain a final search result. According to the embodiment of the invention, the data search efficiency can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data search method, device and storage medium. Background technique [0002] With the continuous advancement of information technology, the popularization of artificial intelligence technology, especially the application of large-scale face recognition technology, the market demand for large-scale vector high-performance retrieval is becoming more and more urgent. The data management strategy in the large-scale vector retrieval scenario is: how to make the data more suitable for the parallel retrieval of the vector retrieval engine, and how to reduce the performance loss of data replacement in all levels of cache. People are experiencing explosive data growth. Unstructured data (such as pictures, videos, voice, and text) grows faster and has a larger volume than traditional structured data. It is called unstructured data because it cannot be processed and valu...
