Abstract

The embodiment of the present invention discloses a command distribution method, device and system in a distributed system. The method includes: receiving the first command carrying the command type sent by the client; when the command type of the first command is used to indicate the first command For reading commands, select a server from the server cluster as the target server according to preset rules, the server cluster includes all servers in the distributed system or servers that store the operation data required by the first command; send the first command to the target server , to trigger the target server to execute the first command. By implementing the embodiment of the present invention, the load on the master server in the server cluster can be reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a command distribution method, device and system in a distributed system. Background technique [0002] In a distributed system, in order to ensure the disaster tolerance of the distributed system, it is necessary to ensure the data consistency of each server in the server cluster (ie, all servers in the distributed system). Among them, in order to ensure the data consistency of each server in the server cluster, one server will be selected from the server cluster as the master server, and the rest of the servers will be used as slave servers. The master server is responsible for receiving the commands sent by the client. When the master server receives When the command is a write command, the master server executes the command and sends it to all slave servers asynchronously for execution. When the command received by the master server is a read command, since the dat...
