Abstract
In embodiments of the present invention, when a duplicate data query is performed on a received data stream, a first physical node which corresponds to each first sketch value and is in a cluster system is identified according to a first sketch value representing the data stream, and then the first sketch value representing the data stream is sent to the identified physical node for the duplicate data query, and a procedure of the duplicate data query does not change with an increase of the number of nodes in the cluster system; therefore, a calculation amount of each node does not increase with an increase of the number of nodes in the cluster system.
