Abstract: The present disclosure provides a vector retrieval method and apparatus, a device and a medium, and relates to the field of artificial intelligence technologies, particularly the fields of cloud computing technologies, big data technologies, or the like. The vector retrieval method includes: acquiring a plurality of candidate vector indexes generated in advance, the plurality of candidate vector indexes being generated based on a plurality of candidate field values included in a target field of original data; acquiring a query vector and a filter condition, the filter condition being used for indicating a condition required to be satisfied by a target vector corresponding to the query vector; if the filter condition includes a target field value required to be satisfied by the target field, determining a target vector index corresponding to the target field value in the plurality of candidate vector indexes; and performing query in the target vector index based on the query vector to obtain the target vector.

Abstract: Provided is a method for processing an oracle region cache, an electronic device and a storage medium, relating to the field of data processing technology, and in particular to the fields of big data, cloud computing, distributed database, intelligent search and other technologies. The method includes: obtaining a benefit parameter of a region to be processed, wherein the benefit parameter is used to represent a difference between benefit and cost of setting the region to be processed in the oracle region cache; and selecting the region to be processed to update the oracle region cache when the benefit parameter of the region to be processed meets a target condition.

Abstract: Provided is a data query optimization method, an electronic device and a storage medium, relating to the field of data processing technology and in particular to the technical fields of distributed database, big data, cloud computing and others. The method includes: determining a plurality of candidate execution plans for a target query request; determining execution costs of the plurality of candidate execution plans; updating the execution costs of the plurality of candidate execution plans based on monitoring data of data nodes involved in the plurality of candidate execution plans, to obtain final costs of the plurality of candidate execution plans; and screening out a final execution plan for the target query request from the plurality of candidate execution plans based on the final costs of the plurality of candidate execution plans.

Abstract: A method for generating an index, and an electronic device are provided. The detailed solution includes: determining a first parameter group and a second parameter group in response to receiving a query request for a first vector database and there being no available index for the first vector database, constructing a first index for the first vector database based on the first parameter group, and querying the first vector database based on the first index; constructing a second index for the first vector database based on the second parameter group in response to meeting a preset condition; and in response to determining that construction of the second index is completed, deleting the first index, and querying the first vector database based on the second index.
