It should be noted that the information retrieval method, device, equipment and storage medium based on the cache database of the present application can be used in the financial field, and can also be used in any field other than the financial field.
The cache is generally applied to a scene where the amount of data is small, the access frequency is high, and the data change is small. A general caching scheme for a scene with very high data access frequency, large data volume and very frequent change is not applicable. The reservation of commemorative coin belongs to such a typical scene, and the processing performance of the system is required to be very high, and the net point residual amount is changed in real time.
In one example, the front-end electronics may buffer the commemorative coin reservation site information to relieve pressure from the back-end commemorative coin reservation system. Because of the large overall data size, higher demands are placed on the memory of the front-end system. If the buffer validity period of the front-end electronic equipment is too short, the pressure on the commemorative coin reservation system of the back-end electronic equipment is very high; if the effective period of the cache is too long, the data can not be reflected to the reservation interface of the client frequently, and the client can always see the residual amount, but the client can not find the reserved amount when actually reserving, so that the client experience is poor, and if the front-end cache is not used, the pressure is completely released to the commemorative coin reservation system, and huge pressure can be generated on the system.
