Abstract

The invention discloses a JSON character string processing method and apparatus. The method comprises the steps of obtaining a to-be-processed JSON character string; splitting the JSON character string according to a first format rule of the JSON character string, thereby generating a field set; and performing aggregation processing on fields in the field set according to preset aggregation processing parameters, and determining aggregation indexes. According to the method and the apparatus, the technical problem of low running efficiency caused by poor deserialization processing performance of JSON during aggregation processing is solved.

Description

technical field [0001] The present invention relates to the field of data storage, in particular to a method and device for processing JSON strings. Background technique [0002] Currently, when storing big data, column storage engines such as Impala are usually used. For data tables with many-to-many associations, there often exist many-to-many associations between entities. When the above-mentioned data tables with many-to-many associations are queried, the overhead of table connection shuffle is relatively high, and the query performance is not very high. [0003] In order to improve the query performance of the column storage engine, multiple pieces of data with many-to-many associations can be stored in a string in JSON (JavaScript Object Notation, JavaScript Object Notation) data format and stored in the same field. Since multiple pieces of data are stored in a string in JSON format, when it is necessary to analyze the data content in the JSON string, it is usually n...
