Abstract

The invention discloses a table deleting method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of obtaining a partition information set of a to-be-deleted table according to a received table deletion request, wherein the partition information set comprises identification information of all partitions of the to-be-deleted table;sending the partition information set to a message queue; processing the messages in the message queue, and finishing deletion operation on all partitions of the to-be-deleted table, wherein for eachprocessed message in the message queue, the message is analyzed to obtain the identification information of the corresponding to-be-deleted partition, and deletion operation is executed according to the identification information of the to-be-deleted partition. According to the method, the operation of deleting the table partition is automatically executed by processing the message in the messagequeue, the operation of deleting the table is automatically and efficiently processed, and the problem that a large amount of labor cost and time cost are wasted in the prior art is solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for deleting a table. Background technique [0002] With the development of business, there are more and more table data. But among more and more tables, due to business reasons or having no value, the number of tables that need to be deleted is also very large. For example, the corresponding underlying data has been archived but the metadata has not been deleted. These tables that need to be deleted are basically external partition tables. When the table is deleted, once the internal table is deleted, the corresponding metadata and folders and files in hdfs will be deleted. External tables only delete metadata, and the corresponding folders and files in hdfs will not be deleted. [0003] And in practical applications, due to business reasons, when designing many tables, the design partitions are more complicated and there are many directories, even tens ...
