Loading quantity statistical method, system and device based on batch stream fusion

The invention relates to a method, a system and a device for counting loading quantity based on batch stream fusion, and the method comprises the following steps: S1, batch processing: obtaining and calculating a resource loading unique hash code and a resource weight of each resource in a shelving state based on a resource table in a business library before a platform opens the market, and writing the unique hash codes and the resource weights into a message system, solving an initial value of the hanging quantity of each supplier and storing the initial value into a database; S2, stream processing: collecting a resource table record in real time after the platform opens the market, and screening a record of shelving operation to generate a new unique hash code of resource hanging and a corresponding resource weight real-time value; S3, batch stream fusion processing: judging whether the new unique hash code of the resource hanging exists in the message system, if so, abandoning the unique hash code, otherwi
