Abstract

An embodiment of the invention provides an operation control method and an operation control device and relates to the technical field of data query. The operation control method includes: acquiring execution status of query statements in query nodes; judging whether the execution status of the query statements in the query nodes are normal or not; if yes, trigging any optional query nodes to cancel execution of the query statements; restarting the query nodes failed and canceled in execution. By the arrangement, normal operation of the query statements is effectively guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data query, and in particular to an operation control method and device. Background technique [0002] At present, many data query engines are usually a large-scale parallel processing system consisting of multiple query nodes. [0003] Taking Impala as an example, the query speed of Impala is extremely fast, but during the running process, the query node may appear to be in the red or yellow state, that is, the query node is running abnormally, causing the query node to fail to work normally and affecting the query efficiency. [0004] In the existing technology, in order to ensure the stable operation of Impala, the status of the query node is usually checked regularly. If the query node appears to be in a red or yellow state, the node is restarted. However, the existing method cannot effectively guarantee the query The node is functioning normally.
