Method and device for updating configuration list of data query engine

Embodiments of the invention disclose a method and a device for updating a configuration list of a data query engine. The method comprises: if a service process of a current node of the data query engine is monitored to start, starting a background monitor thread, monitoring update operation of a configuration file directory of the data query engine; if the update operation of the configuration file directory is monitored, obtaining updated configuration file information; according to the updated configuration file information, performing corresponding updating operation on the configuration list of the current node. The technical scheme used in the embodiment does not need to restart the service process of the node of the data query engine, and can realize dynamic update of the configuration list of the data query engine, and achieves an automatic operation and maintenance effect of the data query engine, so as to reduce burden of operation and maintenance staffs and improve user experience of the data query engine.
