Abstract

Disclosed are a data storage method and a data storage device. The method includes: obtaining data which comprises fields comprising field names and data contents; marking the field names; building an index of the field names, which comprises mapping relationships of the marking and the data contents of the fields; saving the index of the field names and the data contents of the fields as a data record which comprises an index area storing the index and a data storage area storing the data contents. By the method, consumption of storage resources is lowered and data searching efficiency are enhanced.

Description

technical field [0001] The invention relates to data storage technology, in particular to a data storage method and device. Background technique [0002] At present, the storage format that supports access to data records with flexible data fields (Schema-Flexible) includes the field name of each field and the type information of the stored data fields in the record. [0003] The resulting data records can have custom field data and can be correctly retrieved. However, in actual work, there are very few scenarios where completely inconsistent data records or very flexible data fields are stored in the same dataset. Therefore, the method of storing its field name synchronously with the content of the data field will cause the following problems: [0004] 1. In a large number of similar data records, the repeated field names are very long and occupy a large storage space. Once a large amount of data is stored, the storage of the field names will consume a large amount of sto...
