Abstract

The invention discloses a data ranking method and a device based on a HBase database. The method comprises the steps that the to-be-ranked data are segmented into multiple cluster nodes in HBase database, wherein each cluster node after being given the segmented data executes a row-key value ranking method in HBase database; the ranked results for each cluster node are read, and multiple ranking results are obtained, wherein each cluster node after executing the row-key value ranking method and performing rankings on the segmented data obtains a ranked result; the collections of multiple ranking results are determined as the ranking results of the to-be-ranked data. The technical problem that in the prior art the efficiency of data ranking is low is solved.

Description

technical field [0001] The present application relates to the computer field, in particular, to a data sorting method and device based on an HBase database. Background technique [0002] The sorting of data is currently more used in big data statistics, such as sorting the number of website visits, you can check the ranking order of the most visited websites, and then make some decisions. Among them, in the case of sorting data with a small amount of data, using many current fast sorting algorithms, sorting will be a very simple matter. But when the amount of data reaches a certain level, the original simple sorting becomes complicated. For example, when there is 100G of data to be sorted, the system can no longer simply read the data into memory and then perform stand-alone sorting, because no server has 100G of memory, even if there is such a server with such a large memory, it is absolutely impossible. will use all of its memory for sorting. [0003] The sorting method...
