Abstract

The embodiment of the invention discloses a database cache construction method and apparatus, a computer device and a storage medium. The method comprises the following steps: a memory database is preset to store the table names of all data tables in a target database; If a cache creation request is received, acquiring table names of each data table stored in the in-memory database; creating an index module corresponding to a table name of each data table, wherein the index module comprises a primary index, an incremental index and a real-time index; constructing cache of the target database is constructed based on the primary index, the incremental index, and the real-time index. The invention creates an index module to cache the data in the data table for each data table in the target database, which can improve the access efficiency of the data and reduce the access pressure of the database at the same time.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a database cache construction method, device, computer equipment and storage medium. Background technique [0002] In the era of big data, with the continuous enrichment of business, the explosive growth of data poses a severe challenge to the query capability of the database, and the processing of high concurrency and massive data has increasingly become an important factor affecting system performance. When the amount of data in a single table of the database reaches a certain level, if the data is obtained by directly accessing the database, the I / O pressure of the database will be increased, resulting in a decrease in data query performance and seriously affecting the user experience. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a database cache construction method, device, computer equipment, and storage med...
