Abstract

The invention provides a mixed file storage method and device. The method comprises the following steps: reading data in a to-be-stored file; Analyzing the data and generating data details; Generatingpage group element information according to the data details; And storing the data and the page group meta-information into a corresponding storage space according to a preset storage rule. Accordingto the method, the page group original information corresponding to the data is obtained by analyzing the file data, so that the data storage is more perfect and convenient, and in addition, the purposes of meeting the requirement of detail query and meeting the requirement of statistical query are achieved.

Description

technical field [0001] The invention relates to the technical field of hybrid file storage, in particular to a hybrid file storage method and device. Background technique [0002] In big data application scenarios, there are usually two types of application requirements: detailed query and statistical query. Detailed query filters qualified multi-row data from structured data by specifying conditions. For example, taking Hbase as an example, by establishing a row key index, you can quickly query qualified data. Data is usually logically in the form of complete rows. return. Statistical queries usually filter data by specifying conditions, and only need to return the data of certain columns, plus operator operations such as aggregation to complete the final return of statistical data, such as performing groupby operations through hive to complete data aggregation for parquet format . Hbase's row key design and data organization and storage in the form of column families, a...
