The embodiment of the invention provides a business data query method and device, electronic equipment and a readable storage medium, and the method comprises the steps: receiving a business access request sent by a terminal, wherein the business access request carries a business identifier; under the condition that the target response data corresponding to the business access request is in cachereconstruction, acquiring the request concurrency number at a first business processing interface corresponding to the business access request, wherein the first business processing interface corresponds to a same business identifier; wherein the request concurrency number is a target moment when the business access request is received or a corresponding request number in a preset time window including a target moment; and under the condition that the request concurrency number is greater than a first threshold, feeding back a business access result to the terminal according to the cache reconstruction condition of the backup cache set and the target response data. According to the invention, the thread blocking degree can be relatively reduced, the balance between user query and cache reconstruction is realized, and the stability and availability of the server are improved.
Description
technical field [0001] The present invention relates to the field of information technology, in particular to a service data query method, device, electronic equipment and readable storage medium. Background technique [0002] With the rapid development of the Internet and the increase in the number of Internet users, the user's access level and data volume are very large. Due to the user's request response speed, the server system tends to read more and write less, etc., resulting in purely based on the database layer. The query can no longer meet the actual needs, so the NoSQL (Not Only SQL, non-relational database) data storage method is introduced, specifically the introduction of a memory-based non-relational database with Redis (Remote Dictionary Server, remote dictionary service) as the mainstream . However, due to the limited cache memory, the server system will not store all data in the cache layer, but only commonly used data, and set the corresponding expiration ...
