Data query method and device based on cache library, storage medium and equipment

The invention relates to a data query method and device based on a cache library, a storage medium and equipment. When a query instruction for data of a first target field is received, if a buffer pool contains the first target field and the data of the field in the cache library is not changed, the data of the field in the cache library is queried; the first target data corresponding to the first target field is directly obtained from the buffer pool, so that the data processing amount of the repeated query data is reduced; otherwise, generating a first target task for acquiring the first target data and sending the first target task to a cache library, and generating parallel first target sub-tasks of each node by the cache library, so that each node executes the corresponding first target sub-task at the same time to improve the efficiency of acquiring the first target data; the latest first target data can be quickly obtained, and the data query efficiency is improved. 本发明涉及一种基于缓存库的数据查询方法、装置、存储介质和设备，在接收到对
