Methods and devices for storing and searching data

Abstract

The invention discloses methods and devices for storing and searching data. The method for storing data comprises the steps of: classifying and storing performance data acquired in every data acquisition period according to service characteristics in different performance data classes in a performance file; and storing the index information corresponding to every performance data class in a class index file corresponding to the performance file. The method for searching the data comprises the steps of: determining the performance data class to which to-be-searched performance data belongs according to the to-be-searched performance data; searching the index information corresponding to the performance data class in the class index file; and searching the to-be-searched performance data in the performance file according to the index information. According to the method and the device disclosed by the invention, the performance data can be rapidly searched with a high inquiry efficiency, IO (input / output) operation is reduced, the search complexity is decreased, and the performance of disk random reading and writing is improved, thereby the system availability is improved.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a data storage and search method and device. Background technique [0002] In a performance collection system, it is often necessary to periodically collect various performance data from multiple collection points of the equipment. The collection point refers to the physical entity on the device that can provide performance data collection and statistics, and is the designated source for obtaining performance data on the device. These performance data will be stored in a persistent manner. When the collection scale is large, the stored data will be massive. In massive data, it is often necessary to perform some queries. These query conditions include the identification of one or a small number of collection points (the number that can uniquely identify a collection point, which can be a string), the collection time range of performance data, and the value of performance dat...
