Abstract

The invention discloses a data storage system and a data storage method and belongs to the technical field of database processing. The data storage method includes: constructing an index list according to a querying manner for data entries in a first data storage unit; generating a data version number according to a current timestamp; storing every index in the index list into a second data storage unit; acquiring every data entry from the first data storage unit and storing the same in the second data storage unit; determining related one or more data entries according to a querying manner corresponding to each index and acquiring a data entry identification list related to the indexes; relatedly storing the data entry identification list related to each index and a name of each index into the second storage unit; updating a current active data version number to the generated data version number. The data storage system and the data storage method have the advantages that query efficiency for business data can be increased, data can be regularly updated on the basis of time, and new data can be provided for an application server.

Description

technical field [0001] The invention belongs to the technical field of database processing, and in particular relates to a data storage system and a storage method. Background technique [0002] Traditional data storage and access methods are generally based on relational databases or distributed caches based on nosql databases. For the relational database implementation, the data is stored in the disk of the relational database, and the application program accesses the data in the database through SQL statements. Since the syntax of the sql statement is very flexible, it can support complex queries under multiple sorting and multiple grouping conditions, that is, it can support complex query services. However, relational databases need to maintain data consistency and maintain a large number of association relationships, and the data is stored on the hard disk, resulting in slow data query speed, especially in the case of high concurrent access, which will seriously affect...
